Black Bay 54 Blue Lagoon

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.

TUDOR is an award-winning Swiss watch brand, offering watches with refined aesthetics, proven reliability and unique value for money. The origins of TUDOR date back to 1926, when "The Tudor" was first registered as a brand on behalf of the founder of Rolex, Hans Wilsdorf. 

He created the Montres TUDOR SA Company in 1946 to offer watches with the quality and dependability of a Rolex, at a more affordable price point. Because of their robustness and affordability, throughout their history TUDOR watches have been chosen by the boldest adventurers on land, underwater and on ice. Today, the TUDOR collection includes emblematic models such as Black Bay, Pelagos or 1926. Since 2015, TUDOR has also offered mechanical Manufacture movements with multiple functions and superior performance.
