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

The Datejust 31 in reference 178273 exemplifies the elegance of Rolex's Yellow Rolesor construction — the combination of Oystersteel for the case and bracelet middle links with 18-carat yellow gold reserved for the fluted bezel and Jubilee bracelet outer links. This two-tone configuration, introduced as a design signature of the Datejust lineage, creates a visually layered effect that reads as simultaneously sporty and refined. The 31 mm case size positions this reference precisely between the 28 mm Lady-Datejust and the 36 mm mid-size, making it a versatile proposition for a broad range of wrist sizes.

The champagne dial with applied index hour markers presents a luminous, understated surface that complements the warm gold tones of the bezel and bracelet accents. Calibre 2235 — Rolex's dedicated movement for the 31 mm Datejust platform — delivers automatic winding, date complication at three o'clock, and the paramagnetism of the Parachrom hairspring which provides superior resistance to magnetic fields and thermal variation. The fluted 18-carat yellow gold bezel is machined in a single piece and polished to mirror specification.

Carried on the iconic Jubilee bracelet — developed by Rolex specifically for the original 1945 Datejust — the 178273 maintains one of the most comfortable and historically significant link configurations in the watch industry. The five-piece link construction distributes weight evenly and articulates smoothly, making extended wear a pleasure. A watch that balances discretion with unmistakable Rolex identity.
