Rolex Datejust 31 Yellow Rolesor — 24-Diamond Bezel Silver Jubilee Diamond Dial | Ref. 178343

Reference 178343 merges the established Datejust 31 architecture with focused gem-set detailing: a 24-diamond bezel in 18 ct yellow gold, paired with a silver dial featuring factory-set diamond hour markers on a Jubilee pattern. Yellow Rolesor — the combination of Oystersteel and yellow gold — grounds the design in Rolex's traditional two-tone aesthetic, with the warmth of yellow gold concentrated in the bezel and relevant bracelet elements. The diamond-set bezel adds measured brilliance without overwhelming the watch's proportions, while the silver background of the dial allows the diamond indices to catch light cleanly.

The Calibre 2235 movement runs within the 31 mm Oyster case. As a self-winding manufacture calibre fitted with Parachrom hairspring and Paraflex shock absorbers, it offers the long-term reliability and ±2 seconds daily precision of Superlative Chronometer certification. The Triplock crown and Oysterlock clasp system together provide both security and water resistance to 100 metres, standard across the Datejust range regardless of precious metal specification.

For a buyer seeking a diamond-set Datejust 31 with a relatively conservative approach to gem decoration, Ref. 178343 occupies a sensible middle ground. The 24-diamond bezel provides genuine jewellery value without the visual density of a fully paved configuration, and the silver Jubilee diamond dial reads as elegant rather than ostentatious. Yellow Rolesor examples in this reference hold their value well on the secondary market, particularly because the configuration appeals broadly — the combination suits both standalone collectors and those building a mixed-metal Rolex wardrobe.
