Rolex Day-Date 36 Everose Gold — Slate Dial, Diamond Bezel | Ref. 128345RBR

Reference 128345RBR represents the current-generation Day-Date 36 in its most jewel-intensive configuration: an 18ct Everose gold case paired with a factory-set diamond bezel and a slate dial whose cool grey tone creates an unexpected but compelling contrast with the warm rose-gold metal. The 36mm Day-Date has long been the smaller of Rolex's two presidential sizes, and the 128xxx series updates the case architecture with a slimmer profile and improved water resistance over the outgoing 118xxx generation.

Powering this reference is Calibre 3255, Rolex's most advanced mechanical movement. Introduced with the Day-Date 40 in 2015 and subsequently fitted to the 36mm case, the 3255 offers a 70-hour power reserve, Chronergy escapement (patent-protected for its high efficiency), and 14 patents in all. The Parachrom hairspring and Paraflex shock absorbers collectively render the movement significantly more robust than its predecessor, the 3155. The President bracelet in 18ct Everose gold completes the configuration with Rolex's hallmark hidden clasp.

The RBR suffix designates a factory-set rainbow bezel option, which elevates the reference into a collector tier defined by scarcity and design drama. Slate dials on Everose gold cases have attracted considerable secondary-market interest in recent years as buyers seek alternatives to the more conventional champagne and white dial pairings. This is a watch for the discerning collector who prizes both technical modernity and aesthetic boldness.
