Rolex Day-Date 36 Gold — Diamond-Paved Rainbow Sapphire Dial | Ref. 128345RBR

Among the most visually spectacular timepieces in Rolex's current production, the Day-Date 36 ref. 128345RBR in 18ct gold presents a diamond-set bezel alongside a dial paved entirely in diamonds and encircled by rainbow-set sapphires — a confection of chromatic and scintillating brilliance that defines the absolute apex of the Day-Date jewellery watch canon. The "President" bracelet, exclusive to the Day-Date since its introduction in 1956, completes the composition in 18ct gold, reinforcing this piece's identity as a wearable statement of exceptional wealth and taste.

Powering this extraordinary case is Calibre 3255, Rolex's most sophisticated self-winding manufacture movement and the technical centrepiece of the current Day-Date 36. Introduced in 2015, the 3255 incorporates 14 patents, including a Chronergy escapement — a redesigned nickel-phosphorus lever and escape wheel combination that improves energy efficiency by 15 percent — alongside a Syloxi silicon hairspring and Paraflex shock absorbers. The result is an 70-hour power reserve, Superlative Chronometer precision of -2/+2 seconds per day, and a movement that is five times more resistant to magnetic fields than its predecessor.

Ref. 128345RBR occupies a unique position in the Day-Date collector universe: it is simultaneously one of the most expensive watches in Rolex's catalogue and among the most liquid on the secondary market, where demand for high-jewellery Day-Date references consistently outstrips supply. Rainbow sapphire bezels, having appeared across several Rolex sports and dress lines, carry a defining scarcity premium. This is a reference of genuine rarity and exceptional craftsmanship — a watch that functions as both instrument and objet d'art.
