Rolex Day-Date 36 18ct White Gold — Diamond-Set Bezel, White Roman Dial | Ref. 128399TBR

The reference 128399TBR represents the Day-Date 36 at its most resplendent: an 18-carat white gold case whose cool, silvery lustre is amplified by a fully diamond-set bezel of extraordinary gem intensity. Rolex's gemological atelier individually selects, grades, and sets each diamond according to exacting internal standards — the stones of the bezel arranged in an unbroken continuous band that transforms the watch's profile into a scintillating crown in its own right. The white Roman dial beneath introduces a counterpoint of classical sobriety, its Roman chapter ring rendered in high-relief gilt numerals that echo centuries of European horology.

Calibre 3255 — the most advanced movement Rolex has produced for the Day-Date family — beats within the sealed Oyster case. Patented in 2015, it incorporates a Chronergy escapement for improved efficiency, a Parachrom hairspring for magnetic and thermal resilience, and fourteen patents across its architecture. Power reserve has been extended to approximately 70 hours, and the movement's precision is certified by COSC as a chronometer before Rolex subjects it to its own stringent Superlative Chronometer testing, warranting accuracy to ±2 seconds per day after casing.

The President bracelet in 18-carat white gold — with its semi-circular three-piece links finished to a mirror polish — is the bracelet form most closely identified with the Day-Date's prestige since its introduction in 1956. The concealed Crownclasp on the underside maintains the unbroken visual flow of metal across the wrist. Produced in 2024, the ref. 128399TBR is a contemporary statement of maximum Day-Date opulence: a watch that deploys white gold, diamonds, and Calibre 3255 to articulate a standard of craftsmanship that few manufactures can approach, let alone surpass.
