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

Reference 128399TBR is among the most vivid configurations in the current Day-Date 36 catalogue: an 18ct white gold case housing a dial of genuine turquoise stone, set with diamonds, beneath a diamond-set bezel. Turquoise has appeared on Rolex dials in limited runs since the 1970s, but this contemporary iteration pairs the semi-precious stone with modern cutting precision and the engineering advances of the current generation — including 100 metres of water resistance and the latest manufacture calibre.

At the heart of this reference is the Calibre 3255, Rolex's in-house movement introduced with the current Day-Date generation and representing a comprehensive redesign. Its Chronergy escapement improves efficiency by 15 percent over its predecessor, and the Parachrom hairspring — blue in colour — is manufactured from a paramagnetic niobium-zirconium alloy. Power reserve extends to 70 hours. The 18ct white gold President bracelet, with its characteristic semi-circular three-link construction, is exclusive to the Day-Date and reinforces the model's position at the summit of the Rolex canon.

Colour-dial Day-Dates — particularly stone dials in turquoise, meteorite, or malachite — consistently outperform plain-metal dials at auction, driven by their scarcity and visual distinctiveness. The 128399TBR, delivered in 2024 with full box and papers, represents the full extent of what Rolex offers in the Day-Date 36 today. For buyers seeking a reference that functions simultaneously as a serious horological object and a wearable statement piece, few configurations rival this.
