Rolex Cosmograph Daytona White Gold — Black & White Mother-of-Pearl Diamond Dial | Ref. 126579RBR

Reference 126579RBR sits at the outermost edge of the Daytona range — an 18 ct white gold chronograph with a dial combining black and white mother-of-pearl set with diamonds, a diamond-set bezel, and an elastomer-overmoulded bracelet with flexible metal blade construction. This is not simply a Daytona adorned with gemstones; it is a purpose-built gem-set reference engineered to Rolex's full technical standards while presenting as wearable jewelry of the highest order. The mother-of-pearl dial sectors shift subtly with light, ensuring the watch reads differently across various angles and illumination conditions.

Calibre 4131 — Rolex's latest Daytona movement — drives this reference, incorporating a new silicon balance spring and the Chronergy escapement inherited from the broader Rolex manufacture family. Power reserve is approximately 72 hours, a meaningful improvement over the preceding Cal 4130. The diamond-set bezel replaces the conventional tachymetric scale, making this reference a purely aesthetic expression of the Daytona form rather than a functional timing tool — a distinction that defines the gem-set Daytona's specific market position. Water resistance is 100 metres per Rolex's Oyster standard.

Presented as a 2024 reference with box and papers, the 126579RBR is current production and among the most difficult Rolex references to acquire through authorized channels. Gem-set white gold Daytonas have demonstrated exceptional secondary market performance, frequently trading materially above retail when accompanied by complete documentation. This reference is aimed squarely at serious collectors and high-jewelry buyers who require no compromise between chronograph function and gemological presentation — a combination Rolex executes with singular authority.
