Rolex Datejust Yellow Rolesor — Champagne Index Dial, 24-Diamond Bezel | Ref. 178343

Reference 178343 presents the Datejust 31 at its most warmly luminous: a champagne dial — that distinctively mellow, golden-toned lacquer that Rolex has perfected over decades — framed within a 24-diamond bezel set in 18 ct yellow gold, the whole mounted in Yellow Rolesor combining Oystersteel and yellow gold. The tonal harmony of champagne, yellow gold, and diamond is precisely calibrated; the warmth runs through every element from the Jubilee bracelet's polished yellow gold centre links to the sunburst finish of the dial itself.

The movement is the Calibre 2235, the self-winding manufacture calibre Rolex developed specifically for the Lady-Datejust and mid-size Datejust family. Running at 28,800 vph with a 48-hour power reserve, the 2235 incorporates a Glucydur beryllium copper balance wheel and Breguet overcoil hairspring, and the Parachrom variant of that hairspring provides the same magnetic and shock resilience found across Rolex's current movement range. Chronometric performance is certified to COSC standards and further verified by Rolex's own Superlative Chronometer testing.

For collectors with a focus on gem-set Datejust references, the 178343 warrants attention as a Yellow Rolesor variant that achieves coherence through tonal unity rather than contrast. The 24-diamond bezel adds brilliance without disrupting the warm composition, and the champagne dial — rarer in the broader market than white, black, or silver — confers a period-appropriate luxury that connects the modern 31 mm reference back to the golden-age Datejust configurations of the 1970s and 1980s. It wears as an unambiguous statement of classic Rolex glamour.
