Reference 128238-0045 presents the Day-Date 36 in an 18K yellow gold round Oyster case measuring 36 mm, featuring a fluted bezel and scratch-resistant sapphire crystal with a Cyclops lens over the date. The monobloc middle case is completed by a solid case back and a screw-down winding crown equipped with Rolex's Twinlock double waterproofness system, offering water resistance to 100 metres / 330 feet.
The champagne-colour dial is complemented by instantaneous day and date displays in apertures with secure rapid-setting, and stop-seconds for precise time adjustment. Beneath the solid case back runs Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex, with bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, and a power reserve of approximately 70 hours. The movement carries Superlative Chronometer certification — COSC plus Rolex certification after casing.
Completing the watch is the President bracelet in 18K yellow gold, constructed with semi-circular three-piece links and secured by a concealed folding Crownclasp. This example is from the 2022 collection.
