Rolex GMT-Master II 40 mm

The Rolex GMT-Master II 126718GRNR-0001 is a GMT watch with a 40 mm case in yellow gold. The case measures 12.1 mm thick and carries a black ceramic bezel with a two-colour grey and black Cerachrom insert. A scratch-resistant sapphire crystal covers the black dial, with luminous hands and indices for legibility. Inside is the calibre 3285, a self-winding movement with a GMT function and a power reserve of about 70 hours; it also carries chronometer certification. The date and central seconds sit alongside the second time zone display, set independently via the screw-down crown. The watch rides on a yellow gold Jubilee bracelet fitted with a folding Oysterlock clasp and Easylink extension link. That same clasp helps keep the case sealed to its 100 metre water resistance rating.
