Housed in a round 31 mm case crafted from 18 kt Everose gold, this Datejust 31 follows Oyster architecture with a monobloc middle case, solid screw-down case back, and a screw-down Twinlock winding crown for water resistance to 100 metres / 330 feet. Scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the slate dial legible at a glance, while index hour markers complete the clean layout.
The fluted bezel sits atop the Everose gold case, and the wrist presence is completed by a President bracelet featuring semi-circular three-piece links in matching 18 kt Everose gold, secured by a concealed folding Crownclasp. Together, the case and bracelet form a cohesive, all-gold composition centered on that distinctive slate dial tone.
Inside, the perpetual mechanical self-winding Caliber 2236 — a Manufacture Rolex movement — delivers COSC-certified precision rated at -2/+2 seconds per day after casing. A Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers contribute to the movement's resilience, while bidirectional winding via the Perpetual rotor sustains roughly 55 hours of power reserve. The instantaneous date with rapid setting and stop-seconds function round out the practical complications.
