Rolex Day-Date 36 Yellow Gold — White MOP Diamond-Set Dial | Ref. 128348RBR

The Rolex Day-Date 36 in 18 ct yellow gold has long been the watch by which presidential taste is measured, and reference 128348RBR elevates this tradition with a dial of breathtaking opulence. The white mother-of-pearl surface, shaped by the deep iridescence that only genuine nacre can provide, is further adorned with diamond-set hour markers that catch and disperse light with every movement of the wrist. The bezel, set with a cascade of brilliant-cut diamonds, reinforces the jewellery-watch character of this piece without sacrificing the precise horological identity that defines every Day-Date.

At the heart of this reference beats the calibre 3255 — Rolex's most sophisticated self-winding movement, introduced in 2015. Featuring the Chronergy escapement and a 70-hour power reserve, the 3255 carries 14 patents and embodies the most complete re-engineering of a Rolex movement in decades. Its bidirectional Perpetual rotor and optimised barrel geometry deliver chronometric accuracy certified at -2/+2 seconds per day, far exceeding the COSC standard. The day-and-date display, appearing in twin windows at 12 o'clock, advances with instantaneous snap thanks to the movement's programmable cam mechanism.

A 2024 production example accompanied by box and papers, this reference 128348RBR occupies the highest rung of the Day-Date hierarchy. The combination of white MOP dial, diamond bezel, and yellow gold case in a 36 mm format speaks to a collector who prizes refined scale alongside maximum decorative impact. Day-Date pieces in full factory diamond configuration with complete provenance command a consistent premium across secondary markets, and the 128xxx model number confirms the current-generation movement and case updates that distinguish this watch from its predecessors.
