Offered here is the Tudor Black Bay Ceramic, reference 79210CNU—one of the most technically advanced and striking modern dive watches in Tudor's current collection. A modern interpretation of Tudor’s iconic dive watch, this highly technical timepiece features a 41mm matte black ceramic case with a micro-blasted finish, a domed sapphire crystal, a screw-down crown, and a unidirectional black PVD-treated steel bezel with engraved numerals and markings. Fitted on Tudor’s signature black fabric strap, its stealthy all-black aesthetic is complemented by the brand’s most advanced engineering.

Powering the watch is the Tudor Manufacture Calibre MT5602-1U, visible through the sapphire display caseback. The movement is both COSC Chronometer and METAS Master Chronometer certified, ensuring exceptional precision, reliability, and resistance to magnetic fields. Each movement is rigorously tested across six positions, two temperatures, and at both full (100%) and reduced (33%) power reserve. Built for demanding environments, the Black Bay Ceramic offers 200 meters (660 feet) of water resistance in accordance with ISO 22810:2010 standards, a 70-hour power reserve, and anti-magnetic resistance to 15,000 gauss while maintaining chronometric accuracy after exposure.

This preowned example remains in excellent overall condition, showing virtually no signs of wear, with no noticeable superficial scratches on the ceramic case or sapphire crystal. It is offered as a complete set, including its original outer box, Tudor presentation box, hybrid leather rubber strap with an unworn black PVD-treated steel folding clasp and safety catch, complimentary black fabric strap with a cream center stripe and black PVD-treated steel buckle, International Guarantee card dated November 2021, warranty booklet, and user manual.
