Rolex Datejust Yellow Rolesor — White Index Dial, Fluted Bezel | Ref. 126233

Reference 126233 embodies the Datejust 36's enduring mastery of the two-tone idiom. Yellow Rolesor — Rolex's seamless pairing of Oystersteel and 18 ct yellow gold — has defined the Datejust aesthetic since the model's inception in 1945, and this configuration distils it to its purest form: a fluted yellow gold bezel, a clean white lacquer-finished dial with applied index hour markers, and the harmonious Jubilee bracelet that founder Hans Wilsdorf himself specified for the original Datejust.

Powering the 36 mm Oyster case is the Calibre 3235, Rolex's in-house manufacture movement and among the most accomplished automatic ebauches in contemporary watchmaking. The 3235 features a Chronergy escapement — a nickel-phosphorus lever and escape wheel engineered for 15% greater energy efficiency over previous designs — and a Parachrom Breguet overcoil hairspring that confers exceptional resistance to shocks and magnetic fields. The movement delivers a 70-hour power reserve and beats at 28,800 vph, earning Rolex's Superlative Chronometer designation of +2/-2 seconds daily.

The 126233 generation of the Datejust 36, introduced in 2016, represented a meaningful technical and aesthetic refinement over the preceding 116233: the new Calibre 3235 replaced the proven but older 3135, the case dimensions were subtly reworked, and the lug profile was modernised. For collectors, this reference occupies a sweet spot — inheriting the timeless visual grammar of Yellow Rolesor Datejust while delivering state-of-the-art movement technology. The fluted bezel, machined from solid yellow gold, continues to be one of Rolex's most recognisable design signatures.
