Measuring 31 mm across, the Oyster case of this Datejust 31 is crafted in Yellow Rolesor, combining Oystersteel with yellow gold. The bezel is set with diamonds, while a screw-down winding crown with Twinlock double waterproofness and a screw-down case back ensure water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date window sits above the striking dial.
The olive green dial is itself set with diamonds, and the large VI marker features 11 diamonds in its setting. Roman numeral indices and the characteristic Datejust date display give the face its elegant, legible character. The watch rides on a Jubilee bracelet of five-piece links rendered in matching Yellow Rolesor, secured by a concealed folding Crownclasp.
Inside beats the Calibre 2236, a perpetual mechanical self-winding movement produced by Rolex. Featuring a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers, it delivers a precision of -2/+2 seconds per day after casing and carries Superlative Chronometer certification — combining COSC testing with Rolex's own post-casing standards. Bidirectional winding via the Perpetual rotor provides approximately 55 hours of power reserve.
