HIGH-PERFORMANCE ALUMINIUM BRONZE ALLOYWITH BRUSHED FINISHES
The Black Bay Bronze features an imposing bronze case, 43 mm in diameter. An aesthetic reference to the use of bronze in historic ships and diving equipment, the choice of this metal — a high-performance aluminium bronze alloy with brushed finishes — lends a highly functional appearance to the watch and guarantees the development of a subtle and unique patina.
THE TUDOR MANUFACTURE CALIBRE MT5601
This is a variant of the TUDOR Manufacture Calibre developed specifically to equip the Black Bay Bronze model. Slightly larger in diameter and displaying hours, minutes and seconds functions, it bears the reference MT5601, in which “MT” stands for “Manufacture TUDOR”.
In 2015, TUDOR announced its first Manufacture Calibre in its history. A high-performance calibre of excellent precision and proven robustness, it offers a 70-hour power reserve meaning that its wearer can, for example, take off the watch on Friday evening and put it on again on Monday morning without having to 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, held in place by a traversing bridge - a guarantee of its robustness. Furthermore, the movement is certified by the Swiss Official Chronometer Testing Institute (COSC).
The characteristic elements of the new Black Bay Bronze have been drawn from TUDOR’s history. It inherits its general lines, as well as its domed dial and crystal from the 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 drilled holes on the side of the lugs and their particularly pronounced chamfering are also key design features inspired by history.
AN AGED BROWN LEATHER STRAP,OR A WOVEN FABRIC STRAP
TUDOR has identified the historic uses of its watches and reinterpreted them in its latest models. For example, the French Navy had TUDOR watches delivered without bracelets and then fitted them with their own straps, handmade or otherwise. One of them, found on a period watch, is made of elastic recovered from a French rescue parachute.
It is from this ultra-functional relic, recognisable by its central yellow thread, that the beige and brown woven jacquard strap fitted to the Black Bay Bronze descends. It is also accompanied by an aged brown leather strap with an angled cut to accentuate the rustic effect.
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.
It is this relationship with these navies which evokes ideas of travel and adventure that the Black Bay Bronze celebrates.

1/4 - 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.
2/4 - Seconds hand
The hand indicating seconds.
3/4 - Hour and minute hands
The hand on the watch indicating the time.
4/4 - 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.
Push in and then screw down the crown. Your time is now set.

Before the descent
Turn the bezel until the triangle on the graduation is opposite the minute hand. 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.
