Guaranteeing flawless performance by passing the rigorous tests of COSC certification and featuring the highly revered Oyster architecture, this is a stunning timepiece from Rolex which also offers an attractive and tasteful appearance. Displaying hours, minutes and seconds via central hands upon the black background, the clear dial with 10 diamonds as hour-markers also features day display above the brand logo at 12 o'clock as well as date window beneath the Cyclops lens at the three o'clock position. Underneath, the self-winding 3155 caliber with paramagnetic blue Parachrom hairspring and stop seconds for precise setting builds up a power reserve of 48 hours. It is nested behind the solid back of the 36mm 18K yellow gold case which features a fluted bezel, ensures 100m water resistance and is mounted onto a matching 18K yellow gold Oyster bracelet with deployment clasp.
