Patek Philippe replica Unveils Seven Limited-Edition Watches at the Milan Watch Art Exhibition

Tomorrow, Patek Philippe officially launches one of its most anticipated annual events: the Watch Art Exhibition in Milan. From October 2 to 18, visitors to Milan will have the opportunity to admire a vast array of Patek Philippe’s treasured timepieces. This marks the seventh edition of the exhibition since its debut in Dubai in 2012; previous editions have been held in cities such as Singapore (2019) and Tokyo (2023).

Hosted in the historic CityOval building (formerly known as the Palazzo delle Scintille), this latest exhibition showcases over 500 pieces. In addition to numerous masterpieces from the Patek Philippe archives, the brand is taking this opportunity to launch seven stunning limited-edition watches created exclusively for the Italian market. This means that only those residing in the region—such as the area around Lake Como—have the chance to see them in person. Patek Philippe’s tribute to the host country has been a resounding success, with the entire allocation already sold out.

Instantaneous-Display Perpetual Calendar Chronograph: Ref. 5978P-010 Milano 2026 Limited Edition

Since the debut of the Ref. 1518 in 1941, the perpetual calendar chronograph has remained one of Patek Philippe’s signature combinations of complications. It was only a matter of time before the brand infused this classic pairing with one of the most coveted attributes of the 21st century: the instantaneous display. The new Ref. 5978, powered by the new CH 29-535 PS QI movement, perfectly embodies this concept. Limited to 120 pieces, this timepiece marks the first time Patek Philippe has combined two instantaneous complications in a single luxury copy watch, ingeniously merging the manually wound CH 29-535 PS chronograph movement with an instantaneous perpetual calendar mechanism derived from the R CHR 27 PS QI.

Three calendar apertures are arranged in an arc at 12 o’clock, displaying the day, date, and month; the blue numerals and text stand out clearly against a white background and are framed in white gold. As an instantaneous perpetual calendar, these three displays jump simultaneously at midnight—with intervals of just 30 milliseconds—ushering in the new day in the blink of an eye. A moon-phase display sits at 6 o’clock, a day/night indicator at 8 o’clock, and a leap-year indicator at 4 o’clock; all displays feature Italian text, perfectly complementing the calendar functions. An instantaneous 30-minute chronograph counter is positioned at 3 o’clock—where the minute hand jumps to the next minute with every full rotation of the central chronograph seconds hand—while the small seconds sub-dial is located at 9 o’clock.

Both chronographs and perpetual calendars present challenges regarding energy and its efficient, precise management; combining these two complications is no small feat. Driving four discs simultaneously requires far more energy than driving them sequentially. Patek Philippe’s solution is an ingenious mechanism that accumulates energy over several hours and releases it instantaneously to advance the calendar displays in unison. This ensures the instantaneous 30-minute chronograph counter continues to function correctly even while the calendar discs are jumping.

This timepiece, reference 5978, features a striking 42mm platinum Calatrava case, with a thickness of 14.24mm that underscores its commanding presence on the wrist. However, the concave bezel design cleverly draws the eye toward the deep blue sunburst dial, which features a textured center and is framed by a deep black gradient ring.

This all-new movement, comprising 500 components, beats at a frequency of 4 Hz and offers an estimated power reserve of 55 to 65 hours when the minute repeater function is inactive. Naturally, it showcases the brand’s exquisite finishing, visible through the sapphire crystal case back, which also bears the transfer-printed inscription “Patek Philippe Milano 2026.”

World Time Minute Repeater: Ref. 5531G-013/12 Milan 2026 Limited Edition

Next is a highly sought-after timepiece—the Patek Philippe World Time Minute Repeater (Ref. 5531)—which debuted in 2017, created specifically for the “Art of Watches Grand Exhibition” in New York. The latest models continue this tradition, featuring a map of the host city rendered in masterful Grand Feu enamel on the dial. The Ref. 5531G-012 displays a daytime view of Milan’s city center, while the Ref. 5531G-013 depicts the city at night. As with previous versions, the name of the host city, Milan, appears in red on the city disk, while the names of the other 23 cities representing different time zones are inscribed in Italian. fashion men watch

Unlike other World Time minute repeaters that chime the time based on the wearer’s current location, the Ref. 5531 always chimes the local time of the city selected at the 12 o’clock position (indicated by the central hands). To achieve this, Patek Philippe developed the patented self-winding caliber R 27 HU.

Both of these new timepieces are produced in a limited edition of five pieces each. The watches feature elegant white gold cases with hand-guilloché flanks; the minute repeater slide is adorned with Patek Philippe’s signature wave pattern. Each timepiece comes with interchangeable sapphire crystal and solid white gold case backs.

A Tribute to the Italian Flag: References 7147G-010, 7007G-010, and 7047G-010 Milan 2026 Limited Editions

Patek Philippe made a stunning impression at Milan Fashion Week with three Calatrava models that embody Italian flair. Their designs draw inspiration from the bold graphic aesthetic of the 2020 Ref. 6007. Each model incorporates one of the three colors of the Italian flag: the Ref. 7147G Perpetual Calendar (with moon phase) features green; the Ref. 7007 Date model (with sweep seconds) features white; and the Ref. 7047G Minute Repeater features a passionate red. All three models are housed in 38mm fully polished white gold cases—slightly smaller than the 40mm case of the Ref. 6007—and feature a striking embossed carbon-fiber pattern at the center of the dial.

The Ref. 7147G Perpetual Calendar model features a bright green lacquered dial, accented with white gold Arabic numerals and calendar displays in Italian. Like the Ref. 6007, the dial showcases a prominent embossed carbon-fiber pattern at its center, encircled by a snailed minute track and three sub-dials: the day at 9 o’clock, the month at 3 o’clock, and the date and moon phase at 6 o’clock. The watch is powered by the ultra-thin, self-winding Caliber 240 Q—measuring just 3.88mm in height—resulting in a total watch thickness of only 9.72mm. Meanwhile, the limited-edition Ref. 7007 boasts a bold, modern style; its white lacquered dial features charcoal-grey white gold baton hands and Arabic numeral hour markers with white luminous coating, creating a striking contrast against the black inner and outer minute tracks. A date aperture is discreetly positioned at 3 o’clock.wholesale fake watches

This limited-edition minute repeater (Ref. 7047) stands as a masterpiece of Italian craftsmanship. It debuted earlier this year at “Watches and Wonders,” featuring an elegant blue dial with bold orange accents. The latest version—also limited to five pieces—showcases a fiery red dial and a bright red alligator leather strap. It is powered by the self-winding Caliber R 27 PS, equipped with a 22K gold mini-rotor featuring a guilloché pattern.

Aquanaut Date Center Seconds: Ref. 5167A-014 Milano 2026 Limited Edition

The final limited-edition timepiece is the Aquanaut Date and Center Seconds Ref. 5167A. Renowned for its sporty yet stylish aesthetic, this model—limited to 250 pieces—is no exception. It introduces a striking new blue color scheme to a model originally launched in 2007 to celebrate the Aquanaut collection’s tenth anniversary. The watch retains the textured dial featuring the signature Aquanaut pattern—now rendered in a sunburst blue finish—complemented by a black-gradient periphery, red transferred minute markers, a red lacquered seconds hand, and applied white gold hour markers and baton hands. The case dimensions remain unchanged at 40.8 mm in diameter and 8.1 mm in thickness, while the composite strap comes in a matching midnight blue. It is powered by the latest Caliber 26-330 SC, which includes a stop-seconds function for precise time setting.

The Future of Accuracy: Why the Zenith Defy Line is Redefining Modern Sports Watches

The Future of Accuracy: Why the replica Zenith Defy Line is Redefining Modern Sports Watches

Zenith has a storied history, largely defined by the legendary El Primero movement. It is the movement that saved the mechanical chronograph and powered the first Rolex Daytona models. Yet, for years, Zenith seemed content to rest on those laurels. That changed dramatically with the introduction of the Defy line. The Defy is not just a reissue; it is a declaration that Zenith is looking forward, not back.

The star of the show is, without a doubt, the Defy El Primero 21. This isn’t your grandfather’s chronograph. While a standard mechanical chronograph measures elapsed time to a fraction of a second, the El Primero 21 measures it to 1/100th of a second. Visually, this is stunning—the central chronograph hand completes a full revolution around the dial every single second. It is a blur of motion that serves as a visceral reminder that you are wearing a machine operating at an absurd frequency.

If you are in the market for one, a detailed Zenith Defy El Primero 21 buying guide is essential. The line has expanded significantly since its debut, with variations in titanium, ceramic, and even high-end sapphire cases. You need to decide whether you want the standard open-worked dial or the cleaner, more legible closed dial version. From an investment perspective, the Defy line offers one of the best “value for specs” ratios in the luxury sports watch market. It competes directly with the Audemars Piguet Royal Oak and the Patek Philippe Nautilus on the open market, but in terms of pure mechanical innovation, the Defy often beats them at a fraction of the retail price. It is the thinking man’s alternative to the “hype” watches.

Holy Trinity Luxury Watches: Patek Philippe, Audemars Piguet & Richard Mille Full Collector Guide

Compare three elite fashion luxury watch icons: Patek Philippe timeless heritage, Audemars Piguet sport-luxury legacy, and futuristic Richard Mille high-tech performance horology.

Patek Philippe vs Audemars Piguet vs Richard Mille: Modern Holy Trinity Watch Guide

In today’s high-end watch collecting world, three brands define the absolute peak of luxury horology: Patek Philippe , Audemars Piguet , and fake Richard Mille . Often called the modern watch holy trinity, these manufacturers represent three entirely different philosophies: generational heritage, sport-luxury revolution, and futuristic technical innovation. For new collectors building a premium portfolio or investors hunting long-term value, understanding their unique strengths is essential. Patek Philippe: The Benchmark of Timeless Haute Horlogerie

Founded in 1839, Patek Philippe remains the only family-owned Geneva manufacture with uninterrupted independent production. Famous for its iconic motto “You never truly own a Patek Philippe, you merely hold it for the next generation”, the brand sets the global standard for traditional watch craftsmanship. Every model undergoes strict in-house quality control known as the Patek Philippe Seal, delivering unmatched precision, finishing, and long-term reliability. Iconic collections like the Calatrava, Nautilus, and Aquanaut dominate both primary and secondary markets. Patek Philippe specializes in grand complications including perpetual calendars, minute repeaters, and sky moon displays. Unlike trendy sport watches, Patek Philippe luxury watches deliver stable annual appreciation, making them the safest investment-grade timepieces in the entire industry. Audemars Piguet: The Founder of Modern Sport Luxury Watchmaking

Established in 1875 in Switzerland’s Vallée de Joux, Audemars Piguet changed horology forever in 1972 with the release of the Royal Oak, the world’s first luxury stainless steel sport watch. Before the Royal Oak, high-end watches were exclusively crafted from gold or platinum for formal occasions. Audemars Piguet broke all rules, creating wearable luxury that blends bold aesthetics with elite mechanical performance. Today, the brand’s core lineup includes the classic Royal Oak and the rugged Royal Oak Offshore. Audemars Piguet sport watches balance daily wearability, strong street credibility, and consistent collectibility. Compared to Patek’s ultra-formal legacy style, Audemars Piguet targets modern collectors who want luxury that works for both business meetings and casual lifestyles. Richard Mille: Futuristic High-Tech Performance Horology

Founded in 1999, Richard Mille fake is the youngest and most revolutionary of the modern trinity. The brand completely abandons traditional watchmaking rules, building every timepiece like a precision racing machine. Using aerospace-grade Carbon TPT, titanium, ceramic, and ultra-light composite materials, Richard Mille creates skeletonized tonneau-case watches built to withstand extreme shocks, vibrations, and athletic pressure. Unlike Patek Philippe and Audemars Piguet, which focus on classic aesthetics, Richard Mille high-tech watches prioritize innovation, lightweight performance, and visual drama. Famous athlete collaborations and limited-edition skeleton models make Richard Mille the ultimate status symbol for modern celebrities, athletes, and young high-net-worth collectors. Final Collector Breakdown

Choose Patek Philippe for heritage, auction value, and generational wealth preservation. Choose Audemars Piguet for versatile sport-luxury design and daily wear luxury. Choose Richard Mille for futuristic engineering, exclusive materials, and modern elite status. For collectors looking to expand their portfolio beyond the big three, brands like Ulysse Nardin and fake Breitling offer incredible technical value and unique horological heritage.

U-Boat U-51 Chimera Bronze Reference 6945 Reviews

zelin0802

Why We Didn’t Introduce U-Boat Before
If you are not from the Netherlands, Belgium or Luxembourg, you can of course skip this brief introduction. But if you’re wondering why we haven’t shown more cheap U-Boats in the past, read on.

I was on a short trip to London earlier this year and U-Boat UK invited me to meet them. To be honest, I haven’t noticed U-Boat for a long time. The reason is that about 10 years ago they were sold in a terrible way in the Netherlands (where we are). However, I decided to visit U-Boat’s staff in London and to my surprise they admitted that these early days were not the best for U-Boat in some countries such as the Netherlands. However, they’ve come a long way since then and U-Boats seem to be selling really well in the UK (and other countries). Time to put the past behind us and see what the U-Boat is all about.

When the good folks at U-Boat showed me part of their collection, I noticed that the watches still reflected the design they started with, but the level of finish and especially the level of detail has improved in many ways. In fact, you either love these fake watches for sale or you hate them. However, there is very little to discuss about the finish and the vast amount of detail on these watches.

U-Boat background
In 1942, the Italian Navy invited an Italian precision instrument designer and craftsman named Ilvo Fontana to bid for a new officer’s watch and diver’s watch. Ilvo Fontana decided to name the company U-Boat and submitted his design. Due to the circumstances, these watches are out of reach and the design disappears in a drawer. It wasn’t until some 58 years later, in 2000, that Ilvo Fontana’s grandson, Italo, discovered the designs and inspired him to complete what his grandfather had started. To create a diver’s watch with high quality standards and guaranteed maximum visibility and reliability in any light and weather conditions.

The U-42 series returns to the original design of Italo Fontana’s grandfather, and the Chimera series is a modern interpretation of it. The crown system, one of its hallmarks, is clearly present on this watch and expands the case’s 46mm diameter to a staggering 60mm. Let’s zoom in on this bronze work by U-Boat.

Chimera Bronze Limited Edition Ref 6945
The first thing I noticed when I opened this watch out of the box was the weight and size. The watch weighs approximately 185 grams, so you won’t notice this while wearing it. Of course, the most striking feature of this Chimera is the bronze case. The bronze case will eventually take on a patina that is unique to each timepiece. Only limited to 300, I wonder what the difference will be between them a few years (or decades) from now when they age. I’m not sure, but I can imagine the patina on the bronze case also depends on the owner’s geographic location (weather conditions) and of course the type of abuse it will receive.

As you can see, the bezel and case back are secured to the middle case using 5 screws and bolts in the outer bronze tube. The dial of the watch is layered, which adds depth to it. The lower dial is matte bronze and the upper dial is tobacco, giving the watch a vintage look and feel. In any case, it’s a perfect bronzer. Laser-cut minute and hour hands with a hand-brushed finish complete this watch picture-perfect. While very functional, no need for a date aperture in my book.

It also showcases the finishes of the bezel, tubes, case middle and lugs. The satin brushed finish seems to have a different orientation on each part of the watch, showing the level of detail that U-Boat has put into these watches.

Another aspect of the watch that I need to mention here is the strap. Although this watch might look a bit small and thin (as you can see, the watch is quite thick. About 18mm). The calf straps are machined using techniques from the 1800’s, giving it a vintage distressed look and feel. While we’re currently seeing more straps with this finish and typically thick stitching, this has got to be the softest, most comfortable strap I’ve worn in a while. Of course, the replica watches swiss comes with a matching bronze buckle.

If we turn the watch around, you can immediately feel the level of detail that U-Boat loves to put into their watches. Before I detail the mechanical chronograph movement of this Chimera Bronze Limited Edition Reference 6945, I want you to take a look at the case back. The pearl pattern on the bottom cover is done very well. The back of the case has all the necessary text for U-Boat engraved on it, but I’m not sure why you would show the case diameter on it. Maybe that’s the first thing other people will ask you. It didn’t bother me anyway.

The crystals on the back have a bit of a “smoke” effect. It matches the bronze color of the case perfectly and still gives you plenty of “view” of the movement.

As you might have guessed by looking at the dial layout, the U-Boat uses an ETA/Valjoux 7750 based movement. However, the rotors are made of silver and have blued screws that hold the weights in place. The rhodium-plated movement is beautifully decorated. ETA/Valjoux is considered a workhorse, so I’m pretty confident it will continue to tick for generations to come. The version used by U-Boat is a beautiful workhorse though, as we’ve seen smaller (optical) finished versions of this movement in many watch lovers’ more premium branded watches.

To sum it up: I’ll be the last to deny that U-Boats have a troubled history here in the Netherlands, and it kept popping into my head a few times while handling this U-Boat. However, I need to be honest here and have to admit that there is very little to criticize in terms of the quality and finish of this watch. The only thing I have to get used to is the price level of these watches as they are a far cry from the first quartz watches produced in the early 2000’s. I ignored this brand for 10 years (and some of you probably did too) so now I need to re-evaluate my previous opinions (a lot).

If you’re looking primarily at what you get for the money, the price seems more realistic to me. The use of bronze is cool, and the layered dial and bronze hands match it perfectly. I know Italians and design go hand in hand, but I was pleasantly surprised! Design aside, the U-51 Chimera Bronze watch is unquestionably a quality watch in my opinion.

Luxury with character This is a “fantasy cruiser”!

zelin0802

In the watchmaking industry, there is a very special watchmaking brand. It has 176 years of watchmaking history and is the “blue blood aristocrat” in the wholesale replica watch industry. But if you talk about the most daring and avant-garde brands in recent years, there must be It, this brand is Ulysse Nardin. How avant-garde is the Ulysse Nardin watch? Let’s talk about its Freak fantasy series.

The Ulysse Nardin Freak series features “no crown, no dial, no hands”, which subverts our traditional understanding of watches. Moreover, the first fantasy watch in 2001 also uses silicon material, creating a watchmaking world’s first. What we see today is the Freak Cruiser watch from the Freak collection. (Watch model: 2056-131)

The Freak Cruiser watch follows the important features of the Freak fantasy series and incorporates a nautical theme, equipped with a concave and convex wave bezel and a floating anchor-type moving bridge, which is quite cool.

The case is made of rose gold and finished with a polishing process to reveal a lustrous metallic luster. The case diameter is 45 mm.

The watch does not have a traditional crown, how to adjust the time? The Freak can set the time by setting a locking device at 6 o’clock, releasing the locking device and rotating the bezel.

The Freak fantasy series removes the dial and directly exposes the movement device on the movement splint. At the same time, using the operation principle of the Carrousel, the Carrousel device is used to replace the original pointer. The carrousel mechanism rotates once an hour, and the upper bridge in the shape of a hollow anchor can indicate the minutes, and the lower bridge indicates the hours.

We can clearly see the escapement part. The Ulysse Nardin fake uses a two-way escapement, which transmits power to the balance wheel through two silicon escapement wheels. Due to the lightness, antimagnetic and low friction characteristics of the silicon material itself, It reduces friction and eliminates the need to oil the movement.

The movement uses the UN-205 manual winding movement, which has a power reserve of up to 7 days. The back of the watch is engraved with a wave pattern, and there is also a window where we can see the tension of the mainspring and wind the watch in time.

The watch is paired with a brown leather strap and rose gold clasp.

Freak Cruiser fantasy cruiser watch, in the name of the ocean, is imaginative. The Ulysse Nardin Freak series is of great significance to the watchmaking industry. It is not only the first brand to step into the world of silicon materials, but also dares to subvert the tradition and establish the rules of a new world. This spirit can promote traditional watchmaking in the high-tech world. Moving forward in the world, we not only pursue historical heritage and classic traditions, but also pursue innovation and individuality. replica watch wholesale

Greubel Forsey GMT Quadruple Tourbillon

zelin0802

Huygens’ invention of the hairspring in 1675 was a milestone in watchmakers’ long pursuit of precision. However, it doesn’t eliminate the problem of gravity, which is detrimental to the timekeeping of the copy watch, especially in a vertical position. To solve this problem, Abraham-Louis Breguet (1747-1823) conceived the idea of ​​mounting the regulating mechanism (spring, balance and escapement) in a rotating frame. By turning around an axis, usually within a minute, the frame brings the “heart” of the watch into different successive positions, thus averaging the timing changes. Birth of the tourbillon (1801).

To further improve timekeeping, Robert Greubel and Stephen Forsey reimagined the tourbillon principle and then developed their first three fundamental inventions: Double Tourbillon 30° (2004), Quadruple Tourbillon (2005) and 24-Second Tourbillon (2006).

In their GMT Quadruple Tourbillon, the two watchmakers chose to revisit their second invention and take it a step further by combining it with a multi-time zone display.

Robert Greubel and Stephen Forsey showed inventiveness when they combined their second fundamental invention, the quadruple tourbillon, with their pioneering interpretation of the GMT and its oversized rotating globe. Bold and bold. Displaying three time zones and a universal time function, this remarkable timepiece has a unique three-dimensional architecture crafted with exquisite craftsmanship.

According to the principle that the more different the position of the adjustment mechanism moves, the more precise the timekeeping is, Robert Greubel and Stephen Forsey invented the quadruple tourbillon with spherical differential.

From the initial idea, the concept was clear. While it would be challenging to couple four separate tourbillons, they sought a more compact solution. To save space in all three dimensions, they chose to build the tourbillons in pairs in a unique compact cage system, an extremely challenging feat. Each of these two systems is modeled on a 30° double tourbillon, with the first cage rotating at 30° in one minute, mounted in the second upright cage, and completing a full in four minutes rotate.

The inclination of the inner cage, combined with the different rotational speeds of the two cages, focuses on eliminating timekeeping changes due to the Earth’s gravity when the replica men watch is in all usual positions, especially in the stable position. A spherical differential is used to average the timing of the two autonomous oscillators to improve timing performance, and the system has been awarded two patents.

Having mastered the tourbillon, Robert Greubel and Stephen Forsey continued to research and reinterpret other watch mechanisms, in particular one practical and much appreciated complication: the simultaneous display of multiple time zones. In 2011, two Inventor watchmakers expressed their vision for this modern feature in this groundbreaking timepiece, aptly named GMT, and recently joined by GMT Earth. In this patented system, the second time zone display on the separate sub-dial combines with the universal time display to provide an intuitive world time readout thanks to a world first: an oversized earth completes a full revolution every 24 hours, Follow the planet Earth itself.

In combining the quadruple tourbillon with the GMT mechanism, Greubel Forsey copy not only accomplished a major technical feat, but also created a new hand-wound movement composed of 705 parts, including Three rapidly spinning barrels. Inventor watchmakers also tackled this challenge from an architectural point of view, creating a timepiece that expresses a 3D approach on multiple levels. The main hour/minute dial between 1 and 2 o’clock forms the highest point of the dial, highlighted by the case’s subtle asymmetry, complemented by a 72-hour chronograph power reserve display. The next level is at 4 o’clock, where the coaxial small seconds and the second time zone display are adjustable in one-hour increments via push-buttons. between 8:00 and 9:00,

Lateral windows in the asymmetrical part of the case provide unprecedented views of the equator and the southern hemisphere. The four tourbillons are drawn in two pairs on either side of the blue planet, each with an open and transparent structure, held in place by flat black polished bridges, decorated with gold sleeves and hand-polished bevels and countersinks.

The world time is visible through the case back, with a fixed 24-hour scale marking the day/night zone and a disc with three-letter abbreviations representing 24 cities in different time zones. The disc also distinguishes in light colors the time zones that implement daylight saving time (Daylight Saving Time); and those that don’t (displayed on a dark background). The caseback also offers an opportunity to admire the quadruple tourbillon as well as the frosted bridge with jewels set in a gold sleeve. The two complex asymmetrical convex sapphire crystals that protect the dial and caseback also require a high level of expertise.

This contemporary aesthetic masterpiece is available in a unique version of 66 pieces. The first edition of the 11 models is in white gold and is numbered 01/11 to 11/11 on a plate in the center of the dial.

Zenith launches limited edition Defy Zero G sapphire and Defy 21 double tourbillon sapphire watches

zelin0802

Although humans are accustomed to the continued existence of gravity, its influence is a major obstacle to the mechanical watchmaking industry. When the movement is at a rest position, the pulling force of gravity through the movement’s gear train will eventually cause slight errors. For centuries, watch brands have devised complex solutions to counteract the effects of gravity. Although wristwatches (as opposed to pocket watches or clocks) are more mobile and can alleviate most static gravity problems, the traditional remedy for mechanical movement is the tourbillon escapement. By rotating the escapement around its axis, the force of gravity is distributed more evenly throughout the movement, thereby achieving higher accuracy. For its latest high-end version, Zenith uses this tried-and-tested method of counteracting gravity and a more novel gyro stabilizer device. By embracing the present and future of gravity compensation, the limited edition Zenith Defy Zero G Sapphire and Zenith Defy 21 Double-Tourbillon Sapphire make the brand’s watchmaking capabilities a compelling focus.

Zenith Defy Zero G Sapphire and Defy 21 Double Tourbillon Sapphire are designed with a full sapphire case, 46 mm wide. The rest of the Defy 21 series adopts a sharp faceted flat form, but its sapphire material helps to emphasize the futuristic and sporty characteristics of the design in the image. Although many case designs will fall into chaos when presented in sapphire, in these iterations, the narrow bezel, tapered side chamfers and flat half-cap lugs remain clear. Although these clear cases can indeed uninterruptedly view the complex movements inside, they are indeed affected in terms of durability compared to their conventionally produced cousins. The Defy Zero G Sapphire and Defy 21 Double-Tourbillon Sapphire are only 30 meters water resistant, which is disappointing.

Although the dials of Zenith’s Defy Zero G Sapphire and Defy 21 Double Tourbillon Sapphire are gorgeous skeleton displays of the brand’s movement manufacturing capabilities, each model uses a completely different approach. Defy Zero G Sapphire is the more concise design in this pair of series. It adopts an open and airy layout and makes full use of the wide diameter of the case to create dramatic negative space. Although the layout may be simple compared to its counterparts, the execution is by no means so. Materials and finishes range from exposed meteorites to aventurine glass, miniature paintings, carved midnight blue PVD ​​and brushed stainless steel used for skeleton bridges. The chronograph function is located on the 12 o’clock subdial, which combines a dark blue aventurine central part inspired by space and a bright exposed meteorite outer ring. Chemin-de-fer minute tracking. The small seconds dial at 10 o’clock is divided into a meteorite ring and a mottled orange part, which is hand-finished by a professional miniature artist to evoke the appearance of Mars. Zenith’s engraved navy blue PVD continued the starry sky effect of most of the dial in the image, but stopped for a short stay to draw attention to the iconic element of Defy Zero G Sapphire-its gyroscope at 6 o’clock. Module. This unique design does not rotate the escapement along the axis like a tourbillon, but uses a micro gyroscope to keep the escapement components level, regardless of the position of the watch. This is likely to produce an eye-catching spectacle on the wrist, even in the image, the complex frame around the balance wheel is visually impressive.

Zenith fans should be more familiar with the dial layout of the Defy 21 Double Tourbillon Sapphire because it follows the layout created by Zenith x Felipe Defy Double Tourbillon for Only Watch 2021. The complex skeleton design divides itself into three different visual levels, each of which is color-coded to make it easier to identify in the image. The top hollow bridge and the chronograph minute subdial at 3 o’clock are all engraved with blue PVD. The random star pattern highlights the zero-gravity inspiration of the design. For the lower bridge, the minute track, the power reserve indicator at 12 o’clock and the chronograph seconds at 6 o’clock, the brand chose a contrasting grainy silver tone, while the solid bridge forming the bottom layer is finished with pure midnight blue PVD, making them Fade into the background smoothly. The external decimal scale is a direct visual clue to the iconic feature of the Defy 21 Double Tourbillon Sapphire, which is a dazzling 1/100-second central chronograph hand that completes a dial cycle every second. When this unique chronograph element stops, a pair of skeletonized tourbillons at 8 o’clock and 10 o’clock will dominate. One of the tourbillons is used as the escapement of the basic movement, completing a complete rotation every 60 seconds at a beat rate of 36,000 bph, and is used as a running stopwatch. When the chronograph is activated, the second tourbillon is activated, vibrating at an extremely fast frequency of 360,000 bph, rotating once every five seconds. This sense of speed, coupled with the pure existence of a pair of tourbillons, wholesale watches replica

Zenith uses the self-produced El Primero 8812 S manual winding skeleton movement to power the Defy Zero G Sapphire. Viewed from the back side of the watch, the El Primero 8812 S contrasts the open simplicity of the dial side with the raised geometric mesh of engraved blue PVD ​​skeleton bridges and rhodium-plated gear train elements. However, like the dial side, the gyroscope module occupies the center of the image. For the back of this complex device, Zenith uses hand-carved platinum hemispherical weights, decorated with gorgeous craters, reminiscent of the surface of the moon, and decorated with the brand’s star logo on the top. In terms of performance, El Primero 8812 S provides a stable 50-hour power reserve with a steady beat rate of 36,000 bph. For the Defy 21 double tourbillon sapphire, the brand switched to its internal El Primero 9020 automatic tourbillon chronograph movement. Although the dial side uses a layered bridge structure and an eye-catching double tourbillon, the back cover side of the El Primero 9020 provides a relatively simple view. The wide engraved blue PVD bridge is cut away to show the elements of the gear train, but the matching oversized star rotor covers most of the visual space in the image. When the torque-requiring UHF chronograph and its accompanying tourbillon are not used, the El Primero 9020 can provide 50 hours of power reserve at El Primero’s iconic 36,000 bph beat rate, and COSC-certified chronometer-level accuracy . Zenith Defy Zero G Sapphire and Defy 21 Double Tourbillon Sapphire are paired with navy blue Cordura-effect textured rubber straps, and black lining creates a sharp contrast. As an added bonus, buyers of both designs were invited to participate in the exclusive zero-gravity parabolic flight of Novespace, a subsidiary of the French National Space Center. The flight is currently scheduled to take place in Bordeaux, France in February 2022, but the brand does not mention travel accommodation.

The limited-edition Zenith Defy Zero G Sapphire and Zenith Defy 21 Double Tourbillon Sapphire use two completely different but equally spectacular methods of counteracting gravity, both strikingly showcase the brand’s considerable expertise in fine watches. Defy Zero G Sapphire and Defy 21 Double Tourbillon Sapphire are each limited edition.
