Black Bay Fifty-Four Stainless Steel / Lagoon Blue / Bracelet

Self-winding mechanical movement with bidirectional rotor system. Approximately 70 hours power reserve.

The Black Bay 54 represents Tudor's most faithful reinterpretation of its earliest dive watch — the 1954 reference 7922, which was Tudor's first purpose-built diver. At 37mm, the Black Bay 54 recaptures the compact proportions of mid-century tool watches in an era dominated by 40mm-plus cases, making it one of the few modern dive watches that genuinely references the size and wrist presence of its vintage inspiration. The collection demonstrates Tudor's willingness to resist the industry trend toward larger cases, offering collectors who value historical accuracy a watch that wears as the original did.

The TUDOR Black Bay 54 79000-0001 debuted in 2025 as a new variant of the Black Bay 54 with a Blue dial. This model features a 37mm stainless steel case with a mirror-polished steel bezel insert devoid of minute graduations—an aesthetic detail that recalls early dive watches such as the 1954 Oyster Prince Submariner. The sand-textured Blue dial is protected by a domed sapphire crystal and fitted with TUDOR’s signature snowflake hands. The watch is powered by the automatic MT5400, a COSC-certified movement with a 70-hour power reserve, displaying hours, minutes, and central seconds. It is delivered on a five-link stainless steel bracelet with polished center links and a TUDOR "T-fit" clasp offering tool-free micro-adjustment. The screw-down crown and 200-meter water resistance complete a design that blends vintage inspiration with contemporary technical refinement.
