Tudor Black Bay GMT

The Tudor Black Bay GMT M79830RB-0010 is a GMT watch with a 41mm steel case. It measures 14.6mm thick, and the lug width comes in at 22mm. The bidirectional rotating bezel carries a burgundy and blue 24-hour scale in anodised aluminium, set above a domed sapphire crystal. Under the dial runs the self-winding Manufacture Calibre MT5652, a chronometer-certified movement with 70 hours of power reserve. The opaline dial has luminous hands and indices for legibility, and the GMT function is paired with a central seconds display. A screw-down crown secures the case, and the watch rides on a riveted steel bracelet with a folding clasp and safety catch. Tudor rates the case to 200 metres of water resistance.
