Rolex Datejust 31 Yellow Rolesor — Silver Jubilee Diamond Dial | Ref. 178273

Yellow Rolesor — Rolex’s trademarked two-tone pairing of Oystersteel and 18ct yellow gold — defines the 178273’s aesthetic proposition: a 31mm Datejust that balances the warmth of gold appointments with the durability and affordability of steel. The fluted yellow gold bezel draws the eye immediately, setting the tone for the silver Jubilee Diamond dial within: a silver ground populated with diamond hour markers that add a jewellery dimension without overwhelming the watch’s core readability. This configuration has endured across Datejust generations precisely because it bridges the gap between pure steel sport watches and full-gold dress pieces — accessible in price, aspirational in appearance.

The 178273 is powered by a manufacture Rolex movement appropriate to its 31mm case dimensions, offering self-winding convenience and the reliability expected of a Superlative Chronometer certification. The Oyster case, in Oystersteel with yellow gold crown and fluted bezel, provides 100 metres of water resistance — a figure that underscores the Datejust’s practical versatility despite its dressy presentation. The Jubilee bracelet, a five-link design in two-tone yellow Rolesor that Rolex created specifically for the original 1945 Datejust, provides an elegantly flexible fit and is considered among the most comfortable bracelets in Swiss watchmaking.

The 178273 targets the collector or first-time Rolex buyer who wants the full Datejust aesthetic without the premium of solid gold, or who appreciates the design character of Rolesor as a considered choice rather than a compromise. It remains a perennially popular reference in the secondary market and, as an earlier production model, represents the previous generation of 31mm Datejust before Rolex’s updated 278-series. Condition examples with original Jubilee bracelet and unpolished case surfaces command the strongest interest among buyers.
