Rolex Datejust 31 Yellow Rolesor — Champagne Diamond Dial, Fluted Bezel | Ref. 178273

Reference 178273 represents the Datejust 31 in its classical Yellow Rolesor configuration — a pairing of Oystersteel and 18ct yellow gold that Rolex has refined over decades into one of the most recognisable two-tone identities in luxury watchmaking. The champagne dial set with diamond hour markers offers warmth and depth that complement the yellow gold elements of the case and bezel, while the signature fluted bezel provides both decorative purpose and the structural integrity of Rolex's screw-down caseback system heritage.

The movement in this 178xxx-series reference is Calibre 2235, a self-winding manufacture movement developed specifically for Rolex's mid-size and ladies' collections. The 2235 incorporates a Parachrom hairspring — manufactured by Rolex and impervious to magnetic fields — alongside Paraflex shock-absorbing elements that enhance durability. Its 48-hour power reserve and bi-directional rotor winding ensure reliable performance in daily wear. The Jubilee bracelet in Rolesor, with its distinctive five-link design, has been associated with the Datejust since the model's introduction in 1945.

Collectors approaching the 178273 will find a reference that has maintained consistent appeal across successive generations of watch buyers. The champagne-and-diamond dial is a perennial configuration that ages gracefully, avoiding the rapid stylistic obsolescence that affects more trend-driven dial designs. For buyers entering the Rolex secondary market, this reference offers a compelling combination of precious-metal aesthetics, horological substance, and brand heritage at a price point accessible relative to full gold alternatives.
