Rolex Day-Date 36 White Gold — Mother-of-Pearl Diamond Dial, Diamond Bezel | Ref. 128349RBR

Reference 128349RBR sits at the intersection of Rolex's most prestigious collection and its most intensive gem-setting programme. The Day-Date 36 in white gold with a diamond bezel and a mother-of-pearl dial set with factory diamond hour markers is an unambiguous statement of the President watch's enduring position at the summit of Rolex's range — a piece that delivers both the full-calendar complication and the visual vocabulary of fine jewellery within a single, supremely finished case.

Calibre 3255 powers this reference, the movement Rolex introduced in 2015 as the technical centrepiece of the modern Day-Date. The 3255 features 14 patents, a 70-hour power reserve, and the Chronergy escapement — a high-efficiency lever and escape wheel geometry that improves energy transfer while reducing the movement's susceptibility to magnetic fields. The 18 ct white gold Oyster case houses this movement beneath a sapphire crystal with cyclops magnification, and the diamond bezel — confirmed as factory-set by the RBR suffix — is set with brilliant-cut stones across the full circumference. Mother-of-pearl dials are cut from natural bivalve shell, meaning no two examples are precisely identical; the iridescent surface shifts through violet, cream, and silver tones depending on light angle.

For collectors, the combination of white gold, MOP dial, and factory diamond bezel on the current 3255-generation 128xxx reference represents the most complete specification of the Day-Date available. The President bracelet — exclusive to the Day-Date and crafted in matching 18 ct white gold — reinforces the model's singular status. These references hold value tenaciously and are frequently acquired as heirloom-grade investments rather than merely as wristwatches.
