Housed in a 31 mm round Oyster case crafted from Everose Rolesor — a combination of Oystersteel and Everose gold — this Datejust 31 features a monobloc middle case, solid screw-down case back, and a screw-down winding crown with Twinlock double waterproofness, rated to 100 metres / 330 feet. A domed bezel frames the scratch-resistant sapphire crystal, which carries a Cyclops lens positioned over the date window for easy reading.
The white dial presents Roman numeral hour markers alongside a date complication, while the Calibre 2236 perpetual mechanical self-winding movement powers the watch from within. That movement delivers precision of -2/+2 seconds per day after casing, a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 55 hours. The movement is COSC certified.
Completing the piece is a Jubilee bracelet with five-piece links, also rendered in Everose Rolesor, and secured by a concealed folding Crownclasp. Reference 278241-0002 carries the date complication as its sole additional function, keeping the overall presentation refined and legible on the wrist.
