Tudor Black Bay Chrono

Tudor's Black Bay Chrono, reference M79377KN-0003, is a chronograph with a 42 mm carbon composite case. The case is 14.3 mm thick, and the lug width is 22 mm. The Black Bay Chrono uses the self-winding Manufacture Calibre MT5813, a chronometer-certified movement with a power reserve of approximately 70 hours. A domed sapphire crystal covers the white dial, which has black counters and a date at 6 o'clock. The fixed bezel carries tachymetric markings. Both the crown and the push-buttons are screw-down. Tudor rates the case to 200 metres. A hybrid leather-rubber strap with a "tire pattern" is fitted to the watch.
