Rolex Oyster Perpetual 31 mm

The Rolex Oyster Perpetual 31 mm, reference 277203-0001, is cased in steel and gold. The domed bezel sits above a slate dial with luminous hands and indices, giving the watch clear legibility. A scratch-resistant sapphire crystal covers the dial, and the screw-down crown adds to the case's protection. Inside is the calibre 2232, a self-winding chronometer movement with 55 hours of power reserve and a central seconds display. The watch is fitted with a steel Oyster bracelet closed by a folding Oysterclasp with an Easylink comfort extension link. Rolex certifies the movement to Superlative Chronometer standard after casing. Water resistance reaches 100 metres, held by the screw-down crown's Twinlock system.
