Presented in 31 mm, this Datejust 31 is built around a Yellow Rolesor case — a combination of Oystersteel and yellow gold — featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown for waterproofness to 100 metres. The domed bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date adds both clarity and protection.
The dark grey dial is set with diamonds in 18 kt gold settings, creating a striking interplay of depth and light. Hour, minute, and seconds hands work alongside an instantaneous date display with rapid setting, and a stop-seconds function enables precise time adjustment. The Oyster bracelet, constructed from three-piece solid links in Yellow Rolesor, secures with a folding Oysterclasp featuring an Easylink 5 mm comfort extension link.
Power comes from the Calibre 2236, a perpetual, mechanical, self-winding movement from Manufacture Rolex. It offers approximately 55 hours of power reserve, a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, and bidirectional winding via a Perpetual rotor. The movement carries Superlative Chronometer certification, reflecting precision of -2/+2 seconds per day after casing.
