Rolex Day-Date 36 White Gold — Pearl Diamond Dial, Diamond Bezel | Ref. 128349RBR

The Day-Date 36 has been the pre-eminent dress watch for heads of state and cultural luminaries since its introduction in 1956, and reference 128349RBR sustains that tradition with maximum jewellery intensity. The 36mm case in 18K white gold carries a bezel pavé-set with round brilliant-cut diamonds — the 'RBR' suffix confirming the rainbow-brilliant configuration — creating a surround that radiates in every direction from the dial. The sapphire crystal, fitted with a Cyclops lens, magnifies the instantaneous date at 3 o'clock, while the screw-down Twinlock crown ensures integrity to 100 metres.

At the heart of reference 128349RBR beats Calibre 3255, Rolex's most advanced self-winding movement for the Day-Date 36. The 3255 features a paramagnetic Chronergy escapement in nickel-phosphorus alloy that delivers 15% greater energy efficiency compared with a traditional Swiss lever escapement, a Parachrom hairspring with a Breguet overcoil that resists magnetic fields and temperature fluctuations, and Paraflex shock absorbers for enhanced mechanical protection. A bidirectional Perpetual rotor stores approximately 70 hours of power reserve, with the full day and date displayed simultaneously via the model's hallmark twin apertures.

The pearl diamond dial — mother-of-pearl set with diamond hour markers — offers an organic luminosity that no lacquer or metallic surface can rival, the shell's natural iridescence shifting between silver, blush, and champagne depending on the angle of illumination. The President bracelet in 18K white gold, with its semi-circular three-piece links and concealed Crownclasp, provides the formal setting this dial demands. Reference 128349RBR is an unambiguous statement: the Day-Date at its most brilliantly jewelled.
