Rolex Datejust 31 Yellow Rolesor — White Roman Fluted Bezel Dial | Ref. 178273

Reference 178273 in Yellow Rolesor is a study in classical Datejust presentation: the fluted yellow gold bezel, white dial with applied Roman numeral hour markers, and the harmonious two-tone marriage of Oystersteel and 18 ct yellow gold. This configuration traces its aesthetic lineage directly to some of the most celebrated mid-century Datejust designs, when fluted bezels and Roman numerals defined what a dress watch could be.

The 31 mm Oyster case houses Calibre 2235 — the predecessor to the current 2236, and a movement of proven reliability in Rolex's mid-size portfolio. Operating at 28,800 vph with a 48-hour power reserve, the 2235 delivers the accuracy and long-term robustness expected of a Rolex manufacture movement, certified to Superlative Chronometer standards. The Jubilee bracelet, in matching Yellow Rolesor, closes via a folding Crownclasp and provides the comfortable, refined wear experience that has made this bracelet a signature of the Datejust since 1945.

For the collector, the 178273 occupies an interesting transitional position: as a pre-2020 reference predating the upgrade to Calibre 2236, it represents the established Datejust 31 formula in its mature prior-generation form. These references are well-understood by the market, offering strong value relative to current production equivalents. Fluted bezel Rolesor models with Roman numeral dials remain perennially popular, appreciated by those who regard the Datejust as an heirloom piece rather than a fashion statement.
