Tudor Black Bay Ceramic Master Chronometer (Ref. 79210CNU)

A modern milestone in Tudor’s professional dive watch lineage, the Black Bay Ceramic is the Maison’s first model to achieve METAS Master Chronometer certification, marking a decisive step into contemporary high-performance watchmaking. Executed in stealth black ceramic, this reference combines technical excellence with a bold, understated aesthetic.

The watch features a matte black 41 mm ceramic case paired with a matching unidirectional ceramic bezel, creating a cohesive and purposeful presence on the wrist. The black dial is defined by luminous hour markers and Tudor’s iconic snowflake hands, ensuring optimal legibility in all conditions. Its clean, no-date layout reinforces the watch’s tool-watch DNA while maintaining visual balance.

Powering the Black Bay Ceramic is Tudor’s in-house automatic movement, certified by METAS for precision, magnetic resistance up to 15,000 gauss, and long-term reliability. Unlike traditional Black Bay models, this reference (Ref. 79210CNU) is fitted with a transparent sapphire open caseback, allowing a clear view of the movement—an uncommon and highly desirable feature in a ceramic dive watch.

This piece is brand new, factory sealed, with protective stickers still in place and no signs of wear. It is offered as a full set, complete with its original Tudor presentation box, guarantee card, and accompanying booklets. The 5-year warranty card is dated September 2022, providing the buyer with nearly one year and a half of full manufacturer warranty period.

A highly sought-after modern Tudor, the Black Bay Ceramic appeals to collectors and enthusiasts seeking a stealth luxury sports watch with genuine horological substance, daily-wear versatility, and strong long-term value.
