Tudor Black Bay 58 M79030N-0001 39 mm Black Dial

The Tudor Black Bay 58 M79030N-0001 is the black-dial counterpart to the blue version, using a 39 mm stainless-steel case, satin dial and unidirectional steel bezel. Its bracelet, sapphire crystal and screw-down crown maintain a clean, purposeful outline, while 200-metre water resistance confirms the watch's diving role. The no-date display leaves the familiar Black Bay arrangement notably open.

Inside, MT5402 is an automatic calibre with bidirectional winding and hand-winding capability. Its compact 26 mm diameter and 4.99 mm height suit the case, with 27 jewels, a silicon hairspring and a traversing-bridge-secured free-sprung variable-inertia balance. The COSC Chronometer operates at 28,800 vph, Tudor regulates it to -2/+4 sec/day, and its long reserve reaches 70 hours.
