Rolex Sky-Dweller 42 mm

Rolex Sky-Dweller 42 mm, reference 336933-0004, a GMT watch in steel and yellow gold with a 42 mm case. The case measures 14.1 mm thick, and the fluted gold bezel works with the crown as part of Rolex's Ring Command system. A sapphire crystal with a Cyclops lens sits over the date, and the bright black dial shows luminous hands and indices. Inside is the self-winding calibre 9002, a perpetual movement with dual time zones and an annual calendar that only needs adjusting once a year, at the start of March. Power reserve runs to approximately 72 hours, and the movement carries chronometer certification. The Jubilee bracelet, also in steel and gold, closes with a folding Oysterclasp with a comfort extension link. Rolex rates the case to 100 metres.
