Tudor Black Bay 54 M79000N-0001 37 mm Black Dial

The Tudor Black Bay 54 M79000N-0001 distils the dive-watch format into a 37 mm stainless-steel case. Its black satin dial, unidirectional steel bezel and sapphire crystal keep the visual language direct, while the screw-down crown and 200-metre water resistance give the compact watch a clear aquatic purpose. The bracelet completes a deliberately cohesive, no-date composition.

Calibre MT5400 is a hand-windable automatic movement with bidirectional winding and no date mechanism. It measures 30.3 mm across and 5 mm high, contains 27 jewels and uses a silicon hairspring with a free-sprung variable-inertia balance secured by a traversing bridge. The COSC Chronometer runs at 28,800 vph, Tudor regulates it to -2/+4 sec/day, and its reserve extends to 70 hours.
