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

Reference 178273 sits within the 31mm Datejust tier — a size that straddles the traditional boundary between ladies' and unisex proportions, and one that Rolex has populated with a consistently varied range of material and dial options. The Yellow Rolesor construction here combines an 18-carat yellow gold fluted bezel and crown with a stainless steel Oyster case, a configuration that brings luxury without committing fully to a precious metal case. The silver dial features Jubilee diamond-set hour markers, delivering a restrained sparkle that suits both day and evening contexts.

Calibre 2235 powers this reference — a self-winding movement specific to Rolex's smaller-case watches, certified to COSC chronometer standards with a Parachrom hairspring and approximately 48 hours of power reserve. The yellow gold fluted bezel is one of the most enduring visual signatures in the Datejust lineage, its vertically struck channels catching light in a manner that reads as simultaneously classical and contemporary. The Jubilee bracelet, composed of five-piece links, provides a dressier wearing experience than the three-piece Oyster and has historically been the default pairing for jewellery-oriented references.

The 178273 appeals to collectors who want the Datejust's reliable mechanical character wrapped in a genuinely decorative package without the full expense of an all-gold case. The yellow gold and steel Rolesor combination ages gracefully — the steel resists scratching more robustly than gold, while the gold bezel softens over time into a pleasing patina. On the pre-owned market, Jubilee bracelet condition is always a critical inspection point, as the five-piece construction is more susceptible to stretch and wear than the Oyster configuration.
