Rolex Yacht-Master 42 mm

The Rolex Yacht-Master 42, reference 226659-0002, has a case in white gold measuring 42 mm across and 12 mm thick. The bidirectional rotatable bezel carries a black ceramic insert with polished numerals, and a sapphire crystal with a Cyclops lens sits over the date. Inside is the calibre 3235, a self-winding movement certified as a chronometer, with a power reserve of approximately 70 hours. Central seconds and a date display round out the functions, and the hands and hour markers are luminous for legibility in low light. The dial is black. Rolex fits the watch to a rubber strap with a folding clasp in white gold, using the Glidelock extension system for fine adjustment. Waterproofing holds at 100 metres, thanks in part to the screw-down crown.
