Reference 128348RBR-0049 houses all the hallmarks of the Day-Date 36 in one lavish package. The 36 mm Oyster case is crafted in 18 kt yellow gold with a bezel set with diamonds, sealed by a screw-down case back and a Twinlock double waterproofness winding crown for water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The carnelian dial is set with diamonds throughout, while the hour markers in 18 kt gold carry 32 diamonds and the Roman VI and IX numerals in 18 kt gold are set with an additional 24 diamonds. The President bracelet in 18 kt yellow gold features semi-circular three-piece links and a concealed folding Crownclasp, wrapping the wrist in continuous golden form.
Inside beats the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex rated to a precision of -2/+2 seconds per day after casing and certified as a Superlative Chronometer. With a power reserve of approximately 70 hours, bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, and Paraflex shock absorbers, the movement is as purposeful as the dial it drives — delivering instantaneous day and date display alongside stop-seconds for exact time setting.
