Rolex Day-Date 36 Yellow Gold — Carnelian Dial | Ref. 128238

Few watches in the Rolex canon carry the symbolic weight of the Day-Date, and Reference 128238 in 18-carat yellow gold with a carnelian dial is among its most arresting expressions. Carnelian is a semi-precious chalcedony prized since antiquity for its warm, translucent amber-orange hue, and Rolex's lapidaries cut each dial individually from raw stone, ensuring that the natural banding and depth of the mineral is the centrepiece of the watch face. No two carnelian dials are alike — each is a geological artifact.

The 36 mm case in 18-carat yellow gold is classic Day-Date architecture: a fluted bezel (here in yellow gold, its reeded profile unchanged since the model's 1956 debut), Oyster case with a screw-down Twinlock crown, and the proprietary President bracelet — still the only bracelet exclusively reserved for the Day-Date and Lady-Datejust. The day and date apertures at 12 and 3 o'clock confirm the watch's status as the original calendar complication in fine watchmaking.

At the heart beats Calibre 3255, Rolex's seventh-generation perpetual movement, housing 14 patents and delivering a 70-hour power reserve. Its Chronergy escapement — in nickel-phosphorus, non-magnetic — improves energy efficiency by 15 percent over the previous lever escapement. Paraflex shock absorbers and a Syloxi silicon hairspring (in the ladies' variant) or Parachrom blue Breguet (in larger cases) ensure robustness. COSC chronometer certification is a baseline; Rolex's own Superlative Chronometer standard pushes accuracy to ±2 seconds per day.
