Tudor introduced a black ceramic Black Bay in 2019. The case was matte black ceramic, the dial was black, the hands and markers were luminous, and the watch shipped on a fabric strap or rubber. It was a cleanly resolved piece. It also looked unfinished next to other Black Bays, because the bracelet did not match the case.
The 2026 reference 7941A1ACNU finishes the watch. The bracelet is now ceramic too.
The bracelet: three-link ceramic, double folding clasp
Tudor's parent group has built ceramic cases at scale since 2010. Ceramic bracelets are harder, because the material does not flex and bracelet links must articulate without exposing the case to torsion stress at the lug. Monochrome's introduction walks through how Tudor solved it: each link is fired separately, polished on the centre and brushed on the outers, and articulated through a stainless-steel pin running through ceramic sleeves at the joint. The clasp is a double folding design with a Tudor-signed shield.
The link layout is a three-link Oyster-style architecture, not the riveted five-link bracelet Tudor uses on the steel Black Bay 58 and 39. Time and Tide notes that the three-link choice is structural: the centre link carries most of the load, the outers handle articulation, and the geometry survives the rigidity of ceramic better than a five-link layout would.
The case: 41mm, 13.55mm thick, 200m
The case dimensions are unchanged from the 2019 reference: 41mm wide, 13.55mm thick, 49.4mm lug-to-lug. The crown is screw-down, water resistance is 200 metres. The bezel is a unidirectional 60-minute dive bezel with a matte black ceramic insert and white luminous numerals.
The dial is black, sunray-finished, with applied hour markers and Tudor's signature Snowflake hands. The hands and markers are filled with white luminous material that reads bright against the all-black register.
The closed caseback is engraved with the same shield Tudor uses across the Black Bay line.
Calibre MT5602-U: the Master Chronometer version
The movement is the MT5602-U, a Master Chronometer-certified version of Tudor's MT5602. METAS certification means the movement has passed the eight-test Master Chronometer protocol, including resistance to magnetic fields up to 15,000 gauss, accuracy of 0/+5 seconds per day in five positions, and water resistance verified at the cased-up watch level. Teddy Baldassarre's hands-on confirms the 70-hour reserve, an upgrade over the 70-hour MT5602 base from earlier Black Bays.
The Kenissi-built movement runs at 4Hz and uses a silicon hairspring. Tudor and Rolex co-own Kenissi; the movement architecture is shared with the Tudor lineup and pieces of the Chanel J12 lineup that also use Kenissi calibres.
Pricing and where it lands
Listed at $7,725 in the US and CHF 6,300 in Switzerland, around 6,500 euros. Oracle of Time points out that the price is roughly CHF 1,200 above the steel Black Bay 41 on bracelet, which is a defensible premium for a fully ceramic bracelet given the manufacturing complexity.
The 2026 release also coincides with Tudor's centenary year, and Revolution Watch frames it as part of a wider centenary collection that includes a refreshed Royal and a new Monarch. The Black Bay Ceramic with bracelet is the cleanest piece in that line, because it solves a problem that has been visible on every black ceramic Black Bay since 2019.
The watch is now finished. Whether collectors who already own the 2019 fabric-strap version trade up depends on how much the bracelet matters to them. For new buyers, the 7941A1ACNU is the only black-on-black Tudor diver that ships complete from the factory.
