On the occasion of Watches&Wonders 2023 TUDOR enriches the line Black Bay with a new model that embodies, in a modern key, the milestone of the brand's divers: the reference 7922 presented in 1954. Today, the Black Bay 54 (ref. 79000N) pays homage to this historic model, with a 37 mm diameter case and a Manufacture Caliber.

Known to have been evaluated and later adopted by the French and US Navy and widely used by diving professionals, the Oyster Prince Submariner reference 7922 is an extraordinary source of inspiration. The first models that aimed to reproduce this reference were distinguished by their small crown and, favoring a more essential and uniform aesthetic, were devoid of the now emblematic red triangle at 12 o'clock. Black Bay 54 is in line with this tradition and features multiple design details that, however small, make a big difference. This is visible for example in the hands which, in addition to being adapted in proportions, are joined to the base, just like in the 1954 model. The edge of the bezel has also been rethought, with a modern reinterpretation of the ergonomic motif of the reference 7922. Naturally,

Tudor 7922

The Black Bay celebrates many of TUDOR's first diving watches: today, with the new Black Bay 54, the Brand chooses to offer a model that is more faithful than ever to its very first diving watch, the reference 7922. The 37 mm case recalls the classic proportions of the past, but contains in the MT5400 Manufacture Caliber all the modern know-how of TUDOR and It boasts water resistance up to 200 m.

As with reference 7922, the unidirectional bezel lacks a minute scale – harking back to the early 50s, when scuba diving was in its infancy and TUDOR created a watch for the brave few who dared to try their hand at this fledgling sport. The new aesthetic details, however, are not limited to the size of the case and the bezel. The “Lollipop” shaped seconds hand evokes that of the original model. The evolution is also visible from an ergonomic point of view, with a redesigned crown and bezel, both featuring the proportions of the historic model.

Il Black Bay 54 also features absolutely contemporary elements, such as the dial with a satin sunray finish and the “T-fit” clasp that adapts perfectly to the wrist. And above all, a cutting-edge movement: the Manufacture Caliber MT5400. Its one-piece tungsten rotor is exposed and satin-finished with sandblasted details, while the bridges and mainplate have alternating sandblasted and polished surfaces and laser decorations.

Thanks to the variable inertia balance wheel, held in position by a sturdy double bridge with two fixing points, it is designed to guarantee solidity and precision. Together with the anti-magnetic silicon balance spring, this system allows the Manufacture Caliber MT5400 to function in a fully assembled watch within a tolerance range of six seconds (-2/+4). Another notable feature of the MT5400 Manufacture movement is its “weekend-proof” power reserve, ie approximately 70 hours.

l Black Bay 54 is proposed with a three-link bracelet in entirely satin-finished steel with a TUDOR “Tfit” clasp equipped with a system for rapid length adjustment. Easy to use, without the use of any tools and through five positions, this practical system allows the wearer of the watch to instantly and precisely vary the total length of the bracelet up to a maximum of 8 mm. In addition to offering a pleasant sensation to the touch, the ceramic ball bearings on the clasp allow you to close the bracelet easily and safely.

Il Black Bay 54 is also available with a black rubber strap. The strap is equipped with a TUDOR “T-fit” closure and is available in three sizes; It can also be cut to perfectly reflect the wearer's wrist measurements. It features the emblematic “Snowflake” motif inside to offer optimal grip, as well as the contoured shape designed specifically for the Black Bay54.
