Tudor Black Bay 54

Tudor's Black Bay 54, reference M79000N-0001, is a dive watch with a 37mm steel case. The case measures 11.2mm thick, with a domed profile echoed in the sapphire crystal above the black dial. A unidirectional rotating bezel in steel, fitted with an aluminium insert, tops the case, and the screw-down crown carries the Tudor rose in relief. Inside is the manufacture calibre MT5400, a self-winding movement certified as a chronometer with a power reserve of around 70 hours. Central seconds and luminous hands and indices complete the dial layout. The watch is fitted on a three-link steel bracelet with a folding clasp. Tudor rates the case to 200 metres of water resistance.
