Tudor Black Bay 58

The Tudor Black Bay 58, reference M7939A1A0RU-0001, is a dive watch with a 39mm steel case. It measures 11.7mm thick, a proportion that keeps the watch low on the wrist. The unidirectional rotating bezel in steel carries an anodised aluminium insert, and the burgundy dial sits under a domed sapphire crystal with applied markers picked out by luminous hands and indices. Inside is the manufacture calibre MT5400-U, a self-winding movement certified as a Master Chronometer with 65 hours of power reserve. The screw-down crown bears the Tudor rose in relief. Central seconds keep the dial layout simple. A five-link steel bracelet with a folding clasp completes the watch, and Tudor rates the case to 200 metres.
