The sophisticated equipment with a long history is dressed in modern clothing and a clear Breguet style.
Tradition Tourbillon Fusée 7047 combines the clock inventions developed by master watchmakers and the fascinating fusée-and-chain transmission to show its soul in a surprisingly modern suit. Tourbillon Fusée was launched in 2010 and belongs to the Breguet Tradition series, inspired by the practical design guidelines of Breguet’s long-established subscription watches. The Tradition series does not hide the mechanism, but inverts the movement, so you can enjoy it on the dial side. In this case, we are studying two historically significant and interacting precision enhancement devices-the fuse chain transmission and the tourbillon-which are combined with modern titanium and silicon elements and shot peening on the dial. The surface of anthracite forms a sharp contrast. Almost an anachronism, the fusion of past and present makes the models in the Tradition series so unique.
Watches for people
Fleeing to Switzerland in the turbulent years before the French Revolution, Abraham-Louis Breguet returned to Paris in 1795 and rebuilt his studio on the Island of Cité. Although he is known for the extremely complex timekeeping works designed by European royals and has already set foot in marine chronometers, Breguet came up with a completely new concept to attract a wider audience through his “montres de souscription” (subscription watch) Audience. In 1796, Breguet introduced a simple, robust and reliable single-hand pocket watch with a large diameter (61 mm). The symmetrical movement is characterized by a large central barrel, flanked by a gear train and a balance wheel. The simple enamel dial replicates the simple movement design and is the essence of sobriety and legibility. However, what is striking is that Breguet combines the hour and minute hands. Considering the large diameter of the pocket watch, there is enough space to draw detailed minute orbits with markers at five-minute intervals. The bezel and the back cover are hinged and can be easily opened to set the time and wind from the back cover, while the decorative guilloche pattern on the side of the case helps to grip.
Breguet even produced a brochure in 1797 to advertise this watch: “The price of the watch…will reach 600 livres; a quarter of the payment will be paid at the time of subscription; therefore, the manufacturing process does not There will be any delays, and the delivery will be in the order of order.” The collected money will be used to purchase parts to realize his innovative vision for the mass production line. If you want to know where the crowdfunding comes from, this is you Clues.
The Tradition series came out in 2005 and is reminiscent of Abraham-Louis Breguet’s subscription watches-slightly different. The idea is to display elements of the original architecture and movement mechanism on the dial side, including Breguet’s iconic splint. In most Tradition models, the mainspring is located in the center, flanked by the gear train and the balance wheel. Other common features of the Tradition series are the grooved case band, welded lugs, Breguet blued steel hands and guilloche dials, which are the hallmarks of Abraham-Louis Breguet’s invention.

So far, the Breguet Tradition series has always had a variety of models: manual winding (7057); Greenwich Mean Time (7067); automatic retrograde seconds (7097); chronograph (7077); what we introduce in this article Tourbillon Fusée-and-Chain (7047); and automatic retrograde date (7597).
Before looking at the fascinating mechanism, it may be the moment when the homestead is its indication. Although it is also available in 18k rose gold, our model here is a 950 platinum version with a pure gold silver-plated dial and an anthracite movement. Like other cases of traditional collection, the round case has been welded directly with screw rod ears. It measures 41mm span with 15.95mm height and is polished throughout. Unlike some other models in the traditional lineup, however, the barrel is not centered and is placed at 10 o’clock on the dial. The highlight of this model is the spectacular tourbillon mechanism, combined with the fuse link transmission on the right side of the dial. The hour and minute dial is eccentric at 7 o’clock and the power reserve indicator is at 9 o’clock. The narrow bezel and tall box crystal allow for an impressive panoramic view of the dial, and you can appreciate how the tourbillon splint and dial mechanics rise above the almost grazing sapphire crystal.
The background of the mechanical features on the dial is an anthracite gray alloy, and the surface is frosted and sandblasted, giving a surprisingly modern and dark appearance. It is firmly fixed in place by a fan-shaped splint, which echoes the splint used on an antique Breguet pocket watch. The barrel drum (equipped with two mainsprings and a power reserve of 50 hours) has a non-external scale at 10 o’clock. Ordinary lever. This unique power reserve indicator is located directly on the barrel drum, has a deceleration differential system, and has applied for a patent.
Tourbillon and fuse link transmission
Although the fuse link transmission is not among the inventions of Abraham-Louis Breguet, when combined with a tourbillon, the movement’s frequency regularity is optimized. By ensuring constant torque, fusée’s differential gear transmits a continuous flow of energy to the movement. The problem with the power generated by the mainspring is that when it is fully tensioned, it is very high, but when it is loosened, it loses power, resulting in fluctuations in accuracy. The Fusée-and-chain transmission balances the weakening force of the mainspring to ensure that the movement receives a continuous supply of energy to obtain a more accurate speed. swiss watches for sale
To give you an idea of how long the device has been around, in Dominique Fléchon’s erudite masterpiece “The Mastery of Time”, there is a picture by Leonardo da Vinci (Leonardo da Vinci). ) A picture of a conical fusée designed between 1490 and 1500. As Xavier Markl wrote in his article on the constant force dilemma in watchmaking: “The fusée consists of a tapered pulley connected to a chain coiled on the barrel. The fusée has a device for receiving the chain. Spiral. As the circumference of the thread increases, the reducing force of the mainspring is compensated (much like a bicycle transmission). When the mainspring is released, the chain rolls on the barrel and rolls off the fuse. The increased lever of the fusée compensates for the weakened torque of the barrel. The Fusée-and-chain mechanism is complex to manufacture and difficult to adjust, so it is quite expensive… and they also require a lot of space.” From the side, the fusée is like a cone. The pyramid, the chain, if you can untie it, it looks very similar to a bicycle chain!
Perhaps most people’s invention related to Abraham-Louis Breguet is the tourbillon regulator, which he patented in 1801. Breguet’s design aims to solve the problem of gravity that affects the regularity of movement. Breguet’s idea is to install the escapement in a moving bracket and perform one rotation per minute. The one-minute tourbillon of this model 7047 is placed at 1 o’clock. The barette, upper bridge and bracket are all taken from the earliest sketches of Abraham-Louis Breguet. The large-scale 17 mm titanium tourbillon frame and 13 mm titanium balance wheel are fixed by a titanium hollow brushed splint, sandwiched with diamonds and gems. Another Breguet invention was the Breguet balance spring, or Breguet overcoil, in 1795. Breguet was determined to improve Huygens’ flat hairspring in 1675, by raising the last coil in the hairspring and reducing its curvature to become concentric in form. Moving forward for more than two centuries, the Breguet brand has added lighter, more flexible, anti-magnetic, corrosion-resistant and lubrication-free silicon components to the escape wheel and lever.
