Rolex Yacht-Master 37 mm

The Rolex Yacht-Master 37, reference 268622-0002, measures 37 mm across in a steel case with a platinum bezel, a combination Rolex calls Rolesium. A sapphire crystal with a Cyclops lens sits over the date, and the slate dial carries luminous hands and indices for legibility in low light. Inside is the calibre 2236, a self-winding movement certified as a chronometer, delivering approximately 55 hours of power reserve. The bidirectional rotating bezel is graduated for 60 minutes and can be used to time a sail between two points. Central seconds and a date display round out the functions. The steel Oyster bracelet closes with a folding Oysterlock safety clasp that includes an Easylink comfort extension link. The screw-down crown helps keep the case waterproof to 100 metres.
