- Manufacture Calibre MT5612 (COSC)
- 41 mm steel case
- Aged leather strap
Presented at Baselworld 2017, TUDOR’s famous Black Bay divers watch is now available in a new all-steel version with a brushed steel bezel insert. Fitted with the Manufacture Calibre MT5612, the Black Bay Steel model also introduces a date function to the Black Bay family.
EXTRAORDINARYCRAFTSMANSHIP
The characteristic elements of the new Black Bay Steel have been drawn from TUDOR’s history. It inherits its general lines, as well as its domed dial and crystal from TUDOR’s first diving watches. It features the particularly prominent winding crown from the famous 7924 reference of 1958, aka Big Crown, while its characteristic angular hands, known as snowflake, were borrowed from TUDOR watches used by the French National Navy in the 1970s. The line of red text on the dial highlighting the maximum guaranteed water resistance is a rarity seen on certain 7923 references from 1955.
SATIN-BRUSHEDSTEEL
The Black Bay Steel features a 41 mm case. The disc of the rotating bezel is machined from steel and circular satin-brushed for a matt appearance and a highly functional overall effect. The Black Bay Steel retains the characteristic lines and proportions of the Black Bay while embracing all the distinctness of the TUDOR divers’ watch.
TUDOR MT5612 MANUFACTURE MOVEMENTWITH DATE FUNCTION
The Manufacture Calibre MT5612, a variation of the movement presented by TUDOR in 2015, has been developed for the Black Bay S&G model, bringing a date function for the first time to the Black Bay family.
MT5612 is a high-performance calibre of superb precision and proven robustness. With a 70-hour power reserve, a wearer can take off the watch on Friday evening and put it back on again on Monday morning without having to re-set and wind it. Beating to a frequency of 28,800 beats/hour or 4Hz, the movement is regulated by a variable inertia oscillator with silicon balance spring. This is held in place by a traversing bridge, guaranteeing its robustness. Furthermore, the movement is certified by the Swiss Official Chronometer Testing Institute (COSC).
A RIVETED BRACELET,
AN AGED LEATHER STRAP,
OR A FABRIC STRAP
The bracelet of the Black Bay Steel is inspired by the folding riveted bracelets of the TUDOR watches produced in the 1950s and 1960s, which were famous for having the heads of the rivets attaching the links visible on the side of the bracelet. The links also had a distinct stepped construction. These aesthetic details are incorporated into the bracelet of the Black Bay Steel, integrating modern manufacturing methods using solid links.
The Black Bay Steel is available on an aged black leather strap with folding clasp. It also is available with a khaki green fabric strap. Made using the Jacquard technique, a traditional method achieved by a hundred-year-old family business from the St-Etienne region of France, this strap is one of TUDOR’s signature features.
The history of the TUDOR divers’ watch dates back to 1954 and the launch of reference 7922. The first in a long line of ergonomic, legible, accurate and robust divers’ watches, it perfectly embodies the approach formulated by the American architect Louis Sullivan, according to whom the form of an object must follow its function. Furthermore, it laid down the aesthetic and technical foundations of an ideal divers’ watch, those of an understated, functional and reliable tool.
The sixty years that followed the launch of the original 7922 saw the constant improvement of the TUDOR divers’ watch and each model gained unanimous acclaim from professionals in the field, including some of the greatest military navies in the world. The Black Bay Steel is an emblematic model celebrating 60 years of TUDOR divers’ watches with extraordinary craftsmanship.
USERGUIDE
Glossary
1/5 - Winding crown
The winding crown is used to set the time and date and to wind the watch if it has not been worn. The winding crown is screwed down onto the case to ensure water resistance. It must be fully tightened after each manipulation.
2/5 - Seconds hand
The hand indicating seconds.
3/5 - Hour and minute hands
The hand on the watch indicating the time.
4/5 - Date window
The window that displays the current date.
5/5 - Bezel
The unidirectional rotatable bezel allows precise measurement of dive times. For safety, the bezel rotates in one direction only. It is deliberately harder to turn when the zero marker (triangle) is in the 12 o'clock position to avoid inadvertent rotation.
Setting your watch
Step 1/4 - Screwed-Down position
Your TUDOR watch is equipped with a screw-down crown. Once this is fully screwed down against the case, your watch is guaranteed waterproof. With your finger unscrew the crown to position B. Your watch isn’t waterproof anymore.
Step 2/4 - Manual Winding
Before you first use the watch or if it has stopped, you will need to wind it manually by unscrewing the crown and then turning it clockwise; the other direction is inactive.
Step 3/4 - Time Setting
In order to adjust the time, unscrew the crown and pull it out to the last notch. Then turn it in either direction until the hands indicate the correct time. The small seconds hand is stopped during this operation, allowing the time to be set accurately.
Step 4/4
Push in and then screw down the crown. Your time is now set.

During Dive
This indicates the beginning of the dive and is visible in the dark. The duration of the dive is indicated on the graduation on the bezel by the minute hand.
