Tudor Black Bay 54 Blue M79000B

Tudor expands its compact dive watch lineup with the introduction of the Black Bay 54 Ref. M79000B, adding a fresh all-blue execution to one of its most wearable modern tool watches. First launched in 2023, the Black Bay 54 reinterprets Tudor’s earliest dive watches in a reduced 37mm format, blending vintage inspiration with contemporary reliability. This new blue variant builds on that foundation, offering a cooler, more vibrant aesthetic while preserving the simplicity and purpose-driven design that define the model.
The 37mm stainless steel case keeps the Black Bay 54’s defining proportions. It measures 11.2mm thick with a 46mm lug-to-lug, making it compact and well-balanced. The finishing is mostly satin-brushed, with polished bevels adding contrast without excess shine.
