Rolex Datejust 31 Yellow Rolesor — Silver Diamond Dial | Ref. 178343

Reference 178343 is the Datejust 31 in Yellow Rolesor — a combination of stainless steel case with 18ct yellow gold bezel, crown, and Jubilee bracelet centre links — fitted with a 24-diamond channel-set bezel and a silver dial carrying diamond hour markers. The diamond bezel in this configuration uses 24 individual stones set in a continuous band around the case, adding persistent brilliance to the yellow gold's natural warmth. The silver diamond dial then continues the jewellery approach through to the chapter ring, where diamond markers replace standard applied indices. The result is a Datejust 31 that sustains decorative intent across every component facing the viewer.

Calibre 2235 occupies the case — Rolex's self-winding manufacture movement developed for the 31 mm case tier, certified to Superlative Chronometer standards before the introduction of the silicon-hairspring 2236. The 2235's reliability record is extensive, and its service requirements follow standard Rolex intervals. The Jubilee bracelet in Yellow Rolesor provides the five-link, centre-polished construction with an Oysterclasp closure — practical, secure, and aesthetically consistent with the case's two-tone material approach. Rolex's gem-setting workshop handles bezel stone placement, ensuring each of the 24 diamonds is held to the same standard of uniformity applied to the movement components.

Yellow Rolesor with a diamond bezel and silver diamond dial represents a specific market within the Datejust 31 collector base: buyers who appreciate the warmth of yellow gold accents but prefer the cost and casual versatility of a steel-and-gold case over a full-gold reference. This configuration has seen steady secondary market performance across recent years, with buyers in Europe and Asia maintaining consistent appetite for yellow-accented Datejust 31 references in decorated dial configurations. The 178343 offers clear collector logic: finite production, recognisable specification, and the enduring legibility of Rolex's most successful case family.
