Rolex Day-Date 36 Yellow Gold — White MOP Diamond-Set Dial, Fluted Bezel | Ref. 128238

The 128238 is the current-production Day-Date 36 in 18 ct yellow gold with fluted bezel — an enduring configuration that has defined the watch's visual language for decades. Where the Day-Date 40 skews toward a more contemporary aesthetic, the 36 mm case retains the proportions that made this reference the pre-eminent prestige dress watch of the twentieth century. This particular example pairs a white mother-of-pearl dial with diamond-set hour markers, a combination that rewards the wearer with depth and iridescence that printed dials simply cannot replicate.

Calibre 3255 — confirmed here by the retailer — powers this 2024-production reference. The movement represents the current state of the art in Rolex self-winding engineering: 14 patents, a Chronergy escapement, 70-hour power reserve, and COSC-exceeding precision tested to Rolex's proprietary Superlative Chronometer standard of ±2 seconds per day. The 18 ct yellow gold case measures 36 mm across and is waterproof to 100 metres, while the fluted bezel is machined from solid gold rather than applied plating — a detail that matters over decades of wear. Box and papers from 2024 accompany this example, a significant provenance asset.

The 128238 in yellow gold with MOP dial occupies a sweet spot in the secondary market: current-generation movement, classic proportions, and dial specification that appeals equally to traditional Datejust buyers and new collectors drawn to coloured dials. Unisex in sizing, it performs as convincingly with formal wear as with smart-casual dress. For a buyer seeking a Day-Date with maximum long-term wearability and documented provenance, this 2024 reference with full box and papers is an exceptionally sound acquisition.
