Rolex Day-Date 36 White Gold — Turquoise Diamond Dial | Ref. 128239

Turquoise has occupied a privileged position in the decorative arts since antiquity, and nowhere is its chromatic intensity more dramatically expressed than on the dial of the Rolex Day-Date 36 reference 128239. Cut from natural turquoise stone and set into a 36 mm 18ct white gold case with a fluted white gold bezel, the dial presents a vivid sky-blue ground against which diamond hour markers glitter with unapologetic luxury. The Day and Date apertures at 12 and 3 o'clock — Day-Date's defining horological signatures since 1956 — are rendered in crisp white text that reads with authority against the electric blue backdrop. The President bracelet in white gold completes a composition of remarkable chromatic coherence.

Powering this extraordinary piece is the Calibre 3255, Rolex's flagship self-winding manufacture movement, representing the culmination of decades of in-house research. Its Chronergy escapement — combining a redesigned lever and escape wheel geometry — achieves a 15 percent efficiency gain over the preceding Calibre 3135, translating into a 70-hour power reserve that few peers can match. The Parachrom blue hairspring, produced from Rolex's proprietary paramagnetic alloy, remains stable across temperature extremes and is up to 10 times more shock-resistant than a conventional hairspring. Post-casing certification to Superlative Chronometer standards ensures deviation of no more than ±2 seconds per day.

The reference 128239 was launched as part of the 2023 collection, incorporating the current Day-Date 36 architecture with its updated lugs and polished-and-brushed surface finishing. Waterproof to 100 metres and secured by a Crownclasp, it wears with the confidence of a true Oyster professional while presenting with the unabashed glamour of a museum-quality jewel. For collectors drawn to the intersection of natural gemology and mechanical watchmaking, this turquoise-dialled Day-Date is among the most arresting statements the contemporary Rolex catalogue has to offer.
