Tudor Black Bay 58 925

Tudor's Black Bay 58 925, reference M79010SG-0002, is a dive watch cast in 39mm of 925 silver. The case measures 12.7mm thick and carries a satin finish typical of the alloy. A unidirectional rotating bezel in the same silver, fitted with a matt taupe aluminium insert, sits above a domed sapphire crystal. The grey dial uses luminous hands and indices for legibility underwater. Inside is the manufacture calibre MT5400, a self-winding chronometer movement with 70 hours of power reserve. The open case back reveals it through sapphire as well. A screw-down crown secures the case, which is fitted to a taupe textile strap with a silver pin buckle, and Tudor rates the whole to 200 metres.
