Reference 128348RBR-0081 brings together an 18 kt yellow gold Oyster case measuring 36 mm with a bezel set with diamonds and a champagne dial adorned with 10 baguette-cut diamond hour markers. The scratch-resistant sapphire crystal features a Cyclops lens over the date aperture, while the screw-down winding crown employs a Twinlock double waterproofness system for water resistance to 100 metres / 330 feet. The monobloc middle case and screw-down case back complete the hallmark Oyster construction.
The dial displays the full day and date simultaneously through two apertures, with instantaneous setting and stop-seconds functionality for precise time adjustment. Power comes from the Calibre 3255, a perpetual mechanical self-winding movement by Manufacture Rolex, offering a power reserve of approximately 70 hours, -2/+2 seconds per day precision after casing, and a paramagnetic blue Parachrom hairspring paired with high-performance Paraflex shock absorbers. The movement carries Superlative Chronometer certification — meeting both COSC standards and Rolex's own post-casing certification.
On the wrist, the watch rides on a diamond-set President bracelet crafted in 18 kt yellow gold, secured by a concealed folding Crownclasp. The Day-Date 36 in this configuration stands as one of the most jewel-forward expressions in the Rolex catalogue, uniting technical rigor with extensive gem setting throughout the case, dial, and bracelet.
