Tudor Black Bay Ceramic 79210CNU

Brand history

TUDOR was founded in 1926 by Hans Wilsdorf, founder of Rolex, with the goal of offering reliable watches with a sporty character and a modern approach to design. For decades, Tudor built its reputation on robust tool watches for the military and divers. Today, it is one of the most dynamic brands in the world of watchmaking, combining heritage with modern technology. Black Bay is its iconic line—recognizable, bold, and authentic.

Model description

The Black Bay Ceramic Ref. 79210CNU is the most modern interpretation of the classic Tudor diver's watch. The matte, deep black ceramic case gives the watch a technical, almost tactical feel that instantly stands out on the wrist. This is a watch designed for those who value function, durability, and contemporary design—without compromise.

The monochromatic black dial with subtle, contrasting indexes and distinctive "snowflake" hands maintains excellent legibility, while the ceramic bezel perfectly complements the cohesive, rugged aesthetic. This is the Black Bay for individualists—less vintage, more future-tool.

Characteristics

The 41mm diameter case is crafted from matte ceramic , a material that is extremely scratch- and discoloration-resistant. Its approximately 14.4mm thickness underscores the robustness of the construction, while the unidirectional ceramic diving bezel reinforces the model's professional character. The entire watch is protected by a highly resistant sapphire crystal .

At the heart of the watch is the in-house automatic Tudor caliber MT5602-1U , certified by COSC and METAS Master Chronometer . The movement offers a 70-hour power reserve , operates at a frequency of 28,800 vibrations per hour , and uses 25 jewels . It is resistant to magnetic fields up to 15,000 gauss, making it one of the most advanced movements in its class.

The watch is mounted on a hybrid leather-rubber or fabric strap (depending on the configuration), ensuring comfort and stability even in harsh conditions. Water resistance of 200 meters confirms its full-fledged diving pedigree.
