Rolex Oyster Perpetual 36 mm

The Rolex Oyster Perpetual 36, reference 126000-0001, has a 36 mm Oystersteel case with a domed bezel. The case is built around Rolex's monobloc middle case and screw-down back, closed off by a screw-down winding crown. A scratch-resistant sapphire crystal sits over the silver dial, which carries luminous hands and indices for legibility. Inside is the calibre 3230, a self-winding movement with a power reserve of approximately 70 hours, and the watch is certified as a chronometer. Central seconds and stop-seconds for precise time setting round out the display. The steel Oyster bracelet closes with a folding Oysterclasp fitted with an Easylink comfort extension link. The screw-down crown, part of Rolex's Twinlock system, backs up the case's 100 metre water resistance rating.
