New Arrival: Tudor Pelagos 39. Ideally sized dive watch?

Tudor copy updates its line of Pelagos dive watches with a new model in a 39mm case size.

All early releases came in 42mm boxes and this is the first time Tudor has released 39mm Pelagos. The case is always in titanium, and the watch is available with two straps or a matching titanium bracelet. Since 2015, the bracelet version has 8mm fine adjustment as well as 25mm wetsuit extension. This model features a ceramic-polished titanium unidirectional rotating bezel, making this series the norm for dive watches. The exception is the FXD with its bi-directional bezel, which is not certified for diving as it is designed for underwater navigation.

The new watch looks almost identical to its larger 42mm cousins, especially the Ref. M25600TN-0001. The difference is that the ceramic inserts on the Pelagos 39 are given a sun-ray satin-brushed finish, which is unique in the Pelagos collection. Also, the Pelagos 39 has no date, a feature it shares with FXD.

That movement is now the MT5400, which is a smaller version of the MT5612 used in the larger Pelagos. Manufactured by Kenissi, this movement is a shared movement used by Tudor as well as Chanel, Breitling and Norqain.

With its new Pelagos 39 model, Tudor offers a versatile watch at the crossroads between the world of technical diving and urban sophistication.

Equipped with grade 2 titanium, luminescent ceramic composite monobloc hour markers, buckle quick adjustment system and diver’s extensions, the Pelagos 39 model combines Tudor’s professional dive watch heritage with the versatility of a 39 mm case and the striking appeal of a radial satin finish. The blend of light is done on its bezel and dial. The result is a sports watch that combines cutting-edge watchmaking technology with a chic aesthetic that is as comfortable in the city as it is on shore.

The Pelagos 39 model joins TUDOR’s line of technical divers’ watches in a versatile and complementary design. While the Pelagos, Pelagos LHD and Pelagos FXD models continue the pure aquatic technical tradition, offering features designed for highly specialized and relatively niche professional diving, the Pelagos 39 is a compact, versatile traditional mechanical dive watch, It has a sunray satin inlaid on the dial and bezel, which is dazzling.

matte contrast

The aesthetic balance of the Pelagos 39 model is achieved by a fully satin-brushed case that complements the Tudor product line. This contrasts subtly with the radiance of the bezel insert, which is made of black ceramic with an enhanced sunray satin finish, and has indexes in white luminescent material. The diameter of the bezel exceeds the middle case slightly for maximum grip.

The three-dimensional hour markers on the dial are made of monolithic luminescent ceramic composite material, a feature that enhances the technical aesthetics while significantly increasing the luminous surface of the hour markers. The dial is composed of two main elements, a sunray satin-finished flat disc whose subtle sheen contrasts with the matt finish of the 45° conical sandblasted flange. Last but not least, the name Pelagos stands out in a shiny cherry red at 6 o’clock, breaking up the model’s two-tone palette.

Self-made movement MT5400

The Pelagos 39 model is equipped with the original factory movement MT5400. Its construction is designed to ensure robustness, longevity, reliability and precision thanks to its variable inertia balance held in place by a solid beam with two fixing points. Thanks to this balance wheel and non-magnetic silicon hairspring, the manufacturer Caliber MT5400 has been certified by the Swiss Official Chronometer Testing Institute (COSC) as a chronometer whose performance exceeds the standards set by this independent institution. In fact, COSC allows an average variation of a watch’s daily travel time between -4 and +6 seconds relative to the absolute time of a single movement, while Tudor insists on a variation of -2 to +4 seconds in its travel time when it is fully assembled. watches hot replica

Another notable feature is the power reserve of the in-house movement MT5400 which is “weekend proof” of around 70 hours, which allows the wearer to take off the watch on a Friday night and put it back on on a Monday morning without winding it.

Titanium Bracelet and Rubber Strap

The Pelagos 39 model comes with a fully satin-brushed titanium bracelet with a TUDOR “T-fit” clasp for quick length adjustment. The system is easy to use, requires no tools and offers five positions, allowing the wearer to make fine, on-the-fly adjustments to the overall length of the bracelet along an 8mm adjustment window. The clasp also features a 25mm bracelet extension to allow the watch to be worn over a wetsuit.

The Pelagos 39 comes with a second black rubber strap with a titanium pin buckle, connected to the case by titanium end links. A rubber extension is also included to extend the strap further, up to 110mm.

PELAGOS family

The TUDOR Pelagos collection offers a wide range of high-tech mechanical diver’s watches at the forefront of the field. The product line now consists of four models and is the worthy successor to the Tudor tool watch, used by pioneers of underwater exploration all over the world since the 1950s. Suitable for right-handed and left-handed divers respectively, the Pelagos and Pelagos LHD models offer an ergonomic solution that is not only suitable for most underwater environments, but is also specially designed for so-called “saturation” diving thanks to the helium escape valve. Developed with combat swimmers from the French Navy, the Pelagos FXD model is an instrument that allows easy countdown during so-called “oxygen” dives, where the user does not need to descend to depths requiring decompression stops . at last,
