Tudor Black Bay One 41

The Tudor Black Bay One 41, reference M79680-0001, is built with a 41mm steel case. That case measures 12.2mm thick and has a 22mm lug width, with polished and satin finishing. A flat sapphire crystal sits over the anthracite dial. The movement is the manufacture calibre MT5601, a self-winding chronometer with a power reserve of roughly 70 hours. The screw-down crown carries the Tudor rose in relief, and the dial shows central seconds alongside luminous hands and indices. A steel bracelet closes with a folding clasp and safety catch. That same screw-down crown helps keep the case water resistant to 100 metres.
