At 31mm, this Datejust 31 is built around a round Oystersteel and Everose gold case — known as Everose Rolesor — with a monobloc middle case, solid case back, and a screw-down winding crown featuring the Twinlock double waterproofness system. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date display, and the case carries a water resistance rating of 100 metres / 330 feet.
The chocolate dial is set with diamonds throughout, and the large VI hour marker is individually set with 11 diamonds, while Roman numerals complete the chapter ring. The five-piece Jubilee links of the matching Everose Rolesor bracelet secure via a concealed folding Crownclasp, lending the piece its characteristic refined silhouette.
Powering the watch is the Calibre 2236, a perpetual, mechanical, self-winding movement by Manufacture Rolex, rated to a precision of -2/+2 seconds per day after casing and COSC certified. The oscillator features a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers, while bidirectional winding via the Perpetual rotor delivers a power reserve of approximately 55 hours. Complications include an instantaneous date with rapid setting and stop-seconds for precise time adjustment.
