Crafted in 18 kt white gold, the 40 mm Oyster case features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown delivering waterproofness to 100 metres. The bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The blue ombré dial is dressed with Roman numeral hour markers and presents both the day and date in instantaneous apertures with a secure rapid-setting mechanism. A Cyclops magnification lens keeps the date immediately legible at a glance.
Powering the watch is the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex offering a precision rating of -2/+2 seconds per day after casing, a power reserve of approximately 70 hours, and a paramagnetic blue Parachrom hairspring paired with Paraflex shock absorbers. The movement holds Superlative Chronometer certification, combining COSC testing with Rolex's own post-casing standards. The 18 kt white gold President bracelet closes with a concealed folding Crownclasp.
