About this reference
The Tudor Black Bay M79733N-0004 combines a 41 mm stainless-steel case with a champagne satin dial and unidirectional steel bezel. A yellow-gold bracelet changes the visual register, while the screw-down crown, sapphire crystal and 200-metre water resistance keep the watch firmly connected to the Black Bay's diving specification. Its 14.7 mm thickness gives the case a deliberate, substantial presence.
Calibre MT5612 is an automatic movement with bidirectional winding, hand-winding and instantaneous date correction. It measures 31.8 mm in diameter and 6.5 mm high, with 26 jewels, a silicon hairspring and a free-sprung variable-inertia balance secured by a traversing bridge. The COSC Chronometer runs at 28,800 vph, is rated by Tudor to -2/+4 sec/day, and stores 70 hours of reserve.
