Measuring 36 mm, the 18 kt yellow gold Oyster case features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown rated waterproof to 100 metres / 330 feet. Scratch-resistant sapphire crystal with a Cyclops lens magnifies the date, while the bezel is set with diamonds for added brilliance.
The white dial is laid out with Roman numerals and displays the day and date in dedicated apertures via instantaneous, secure rapid-setting. A stop-seconds function allows for exact time setting, rounding out the practical side of a distinctly dressy watch.
Powering it all is the Calibre 3255 perpetual, mechanical, self-winding movement — a Manufacture Rolex calibre certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. The bidirectional Perpetual rotor, paramagnetic blue Parachrom hairspring, and high-performance Paraflex shock absorbers deliver an approximately 70-hour power reserve.
