Reference 128348RBR-0048 presents the Day-Date 36 in its most embellished form: a 36 mm Oyster case crafted from 18 kt yellow gold, its bezel set with diamonds, and a screw-down case back and winding crown providing water resistance to 100 metres. The scratch-resistant sapphire crystal features a Cyclops lens over the date, while the white dial anchors the look with understated contrast against the surrounding brilliance.
The diamond-set President bracelet in 18 kt yellow gold secures via a concealed folding Crownclasp, completing a cohesive all-gold composition adorned throughout with stones. Every detail of the case architecture follows Rolex's Oyster construction, including a monobloc middle case and Twinlock double waterproofness system at the crown.
Inside beats the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex offering approximately 70 hours of power reserve and a precision rating of -2/+2 seconds per day after casing, qualifying it as a Superlative Chronometer under both COSC and Rolex certification. Functions include centre hour, minute, and seconds hands alongside instantaneous day and date displays with secure rapid-setting and stop-seconds for precise time adjustment. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers.
