Rolex Day-Date 36 Platinum — Turquoise Diamond Dial | Ref. 128236

Few dial materials in contemporary watchmaking carry the immediate visual authority of turquoise, and Reference 128236 exploits this quality to striking effect. The 36 mm platinum case — characterised by its naturally white, dense lustre and the subtle brushed flanks of the Datejust-derived lug profile — frames a dial in carved turquoise stone set with diamond hour markers. Turquoise is a phosphate mineral whose specific colour varies with copper and iron content, meaning no two dials are chromatic duplicates; Rolex selects stones for tonal consistency but the inherent material variation ensures that each 128236 possesses an individual character that polished lacquer dials cannot replicate.

The diamond indices punctuate the turquoise surface with prismatic precision, each stone individually set in white gold mounts that are flush with the dial plane. The interaction between the opaque, matte mineral and the faceted transparency of the diamonds produces a sustained visual tension that rewards extended examination. The fluted bezel, exclusive to certain Day-Date configurations and executed here in platinum, echoes the fluting motifs found across the Datejust and Day-Date families while providing a formal perimeter appropriate to the dial's semi-precious character.

Reference 128236 is powered by Calibre 3255, the most technically advanced movement Rolex has developed for the Day-Date platform. Its Chronergy escapement — a nickel-phosphorus lever and escape wheel — reduces frictional losses and improves energy transfer efficiency by a documented 15 percent over the outgoing design. The 70-hour power reserve, delivered via a bidirectional rotor in 22 ct gold, and the Paraflex shock absorption system ensure that a watch of this gemological rarity is equally protected against the mechanical stresses of daily wear. The President bracelet in platinum, with its concealed Crownclasp, provides a finish wholly consistent with the 128236's position at the apex of the Day-Date range.
