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

Reference 128399TBR represents the Day-Date 36 at its most opulent — a President's watch that fully embraces Rolex's mastery of high jewellery. Crafted entirely in 18ct white gold, this 36 mm configuration pairs a diamond-set bezel with a white mother-of-pearl dial set with diamond hour markers, creating a composition of depth and iridescence that shifts under varying light. The bracelet, in matching 18ct white gold, completes a wrist presence that is both commanding and refined. Produced in 2024, this is a current-generation example in unworn condition.

At its heart beats the Calibre 3255, one of Rolex's most advanced manufacture movements. Featuring a Chronergy escapement — a patented design that improves efficiency by approximately 15% over conventional lever escapements — the 3255 delivers a 70-hour power reserve alongside a Parachrom hairspring, bidirectional Perpetual rotor, and Rolex's proprietary high-performance lubricants. Certified as a Superlative Chronometer, it is accurate to ±2 seconds per day, well beyond COSC requirements. Water resistance is rated to 100 metres.

The 128399TBR is among the most coveted configurations in the modern Day-Date line, with its full-diamond bezel and MOP dial combination holding remarkable appeal for collectors who view timepieces as wearable jewellery investment. Presented complete with box and papers from 2024, this example offers full traceability — a critical factor for the high-jewellery segment where provenance and condition premiums are substantial. For those seeking the ultimate expression of the Day-Date's Presidential legacy, this reference is difficult to surpass.
