Rolex GMT-Master II 40 mm

Rolex's GMT-Master II 126713GRNR-0001 is a 40 mm GMT watch in steel and gold. The case measures 12.1 mm thick and carries a black ceramic bezel for tracking a second time zone. A sapphire crystal covers the black dial, with luminous hands and indices for legibility. Inside is the calibre 3285, a self-winding movement with GMT function and a power reserve of about 70 hours; it is certified as a chronometer. The date sits alongside the central seconds display, both easy to read at a glance. The bracelet is steel and gold, fitted with a folding Oysterlock safety clasp and an Easylink comfort extension link. The screw-down crown helps keep the case rated to 100 metres of water resistance.
