Tudor Black Bay Chrono

The Tudor Black Bay Chrono M79360N-0011 is a chronograph with a 41 mm steel case. It measures 14.4 mm thick and the lugs take a 22 mm strap or bracelet. A domed sapphire crystal covers the black dial, which carries luminous hands and indices along with a date window. The fixed bezel has a tachymetric scale on a black aluminium insert, matched to the chronograph's own tachymeter function. Inside is the self-winding calibre MT5813, a COSC-certified chronometer movement with flyback chronograph and small seconds, running on a power reserve of about 70 hours. The case is fitted to a steel rivet-style bracelet with a folding clasp. Water resistance reaches 200 metres, courtesy of the screw-down crown and pushers.
