Sized at 31 mm, this Datejust 31 is built around a round White Rolesor case featuring a monobloc middle case, solid screw-down case back, and a screw-down Twinlock winding crown for waterproofness to 100 metres / 330 feet. The fluted white gold bezel adds a distinctive contrast, while the scratch-resistant sapphire crystal incorporates a Cyclops lens positioned over the date window.
The dark grey dial offers a Chromalight display with long-lasting blue luminescence for legibility in low light, complemented by an instantaneous date with rapid setting and stop-seconds for precise time adjustment. Powering the watch is Calibre 2236, a perpetual mechanical self-winding movement with a Syloxi silicon hairspring, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and an approximate power reserve of 55 hours. Precision is rated at -2/+2 seconds per day after casing, and the movement is COSC certified.
The Oystersteel Oyster bracelet is constructed from three-piece solid links and closes with a folding Oysterclasp featuring an Easylink 5 mm comfort extension link, allowing for easy on-wrist adjustments.
