Tudor Black Bay 54 Bay Fifty-Four Stainless Steel / Lagoon Blue / Bracelet
Reference 79000-0001
About this watch
The TUDOR Black Bay 54 [REFERENCE] 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.
