Rolex Datejust 31 Yellow Rolesor — Silver Diamond Dial, 46-Diamond Bezel | Ref. 178383

Reference 178383 occupies a distinctive position in the Datejust 31 family as one of the most jewel-intensive expressions of the line. Constructed in Yellow Rolesor — Rolex's proprietary combination of Oystersteel and 18-carat yellow gold — it pairs a 46-diamond-set bezel with a silver dial carrying Roman VI hour markers rendered in diamonds, delivering an aesthetic that bridges sporting elegance with high jewellery craft.

Powering the watch is Calibre 2235, a self-winding movement produced entirely in-house and fitted with a Microstella regulation system for precision rating to +/- 2 seconds per day. The 31 mm Oyster case carries Rolex's characteristic bidirectional rotatable bezel set with 0.58 carats of VS-clarity diamonds, while the fluted crown-protection system ensures water resistance to 100 metres. The President or Jubilee bracelet — a natural companion to this configuration — completes a package whose material quality is evident at every point of contact.

This reference appeals to collectors who appreciate the intersection of gem-setting mastery and mechanical rigour. The 178xxx generation represents the final evolution of the 31 mm Datejust before the 278xxx transition, making well-preserved examples increasingly sought after in the secondary market. It suits a wearer who regards the wristwatch as a considered luxury statement rather than purely a timekeeping instrument.
