The TUDOR Black Bay Ceramic M7941A1ACNU-0001 debuted in 2026 as an updated full-black ceramic interpretation of the Black Bay, introducing a matching ceramic bracelet to the model first launched in 2021. It combines a 41 mm matt black ceramic case with a charcoal domed dial, black ceramic bezel insert, and the METAS-certified Manufacture Calibre MT5602-U.
Its monobloc ceramic case measures 41 mm in diameter, 13.55 mm in thickness, and 49.4 mm lug-to-lug. The case is executed in matt black ceramic with a micro-blasted finish. The unidirectional bezel is made of black PVD-treated 316L steel and fitted with a black ceramic 60-minute insert with sunray satin finish and engraved markings. The screw-down crown is also in black PVD-treated 316L steel, with the TUDOR rose in relief and a circular satin-brushed steel crown tube. A domed sapphire crystal covers the dial, and water resistance is rated to 200 metres.
The dial is charcoal, domed, and finished with a sunray surface. Applied hour markers and the characteristic Snowflake hands are rendered in a darkened palette and filled with Grade A Swiss Super-LumiNova. The display consists of central hours, minutes, and seconds. Across the exterior, the watch follows the blacked-out treatment of the model, with black ceramic, charcoal, and dark luminous details used consistently throughout.
Inside is the Manufacture Calibre MT5602-U, a self-winding mechanical movement with bidirectional rotor system, central seconds, and stop-seconds for precise setting. The movement is certified by both COSC and METAS, operates at 28,800 beats per hour, uses 25 jewels, measures 31.8 mm in diameter and 6.5 mm in thickness, and delivers a 70-hour power reserve certified by METAS. Its construction includes a variable inertia balance with micro-adjustment screw and a non-magnetic silicon balance spring.
The watch is fitted with a full ceramic bracelet in matching black, closed by a proprietary dual folding ceramic clasp. This bracelet is the key distinguishing feature of this reference within the Black Bay Ceramic line, extending the model’s ceramic construction beyond the case to the full bracelet architecture
