Housed in a 36 mm round Oyster case crafted from 18k yellow gold, reference 128238-0113 features a fluted bezel and a solid case back secured by a screw-down winding crown with Twinlock double waterproofness. Scratch-resistant sapphire crystal with a Cyclops lens over the date protects the white dial, which carries Roman numeral hour markers and displays both the day and date through dedicated apertures. The case is waterproof to 100 metres / 330 feet.
The 18k yellow gold President bracelet is composed of semi-circular three-piece links and fastens with a concealed folding Crownclasp, lending the watch its characteristic presence on the wrist. Power comes from Rolex Calibre 3255, a perpetual mechanical self-winding movement offering approximately 70 hours of power reserve and a precision rating of -2/+2 seconds per day after casing. The oscillator relies on a paramagnetic blue Parachrom hairspring and Paraflex shock absorbers, and the watch carries Superlative Chronometer certification reflecting both COSC and Rolex's own post-casing standards.
From the 2022 collection, this Day-Date 36 delivers instantaneous day and date setting, stop-seconds for precise time adjustment, and bidirectional self-winding via a Perpetual rotor — combining the practical with the ceremonial in a format that has defined the Day-Date lineage.
