Rolex Datejust 31 Yellow Gold — Champagne Concentric Circle Arabic Dial | Ref. 178238

Presented entirely in 18ct yellow gold, the Datejust 31 ref. 178238 with a fluted bezel and a champagne concentric circle dial with Arabic numerals represents one of the more characterful expressions in the mid-size Datejust family. The champagne dial — its surface rendered in a pattern of radiating concentric circles that generates depth and movement — carries Arabic numeral hour markers that impart a less conventional, more approachable personality than the classic baton or Roman indices. Paired with a solid yellow gold Oyster or Jubilee bracelet, the overall effect is one of discreet, warm opulence.

Ref. 178238 houses Calibre 2235, the self-winding in-house movement purpose-built for the 31 mm Datejust. Operating at 28,800 vph, the 2235 incorporates a Glucydur balance wheel and Parachrom hairspring — Rolex's proprietary paramagnetic blue alloy that resists magnetic fields up to ten times more effectively than conventional hairspring materials. Certified as a Superlative Chronometer to -2/+2 seconds per day, the calibre matches exceptional accuracy with the robustness expected of Rolex's manufacture movements. Water resistance reaches 100 metres through the Twinlock screw-down crown.

Solid 18ct gold Datejust references occupy a prestige tier above Rolesor examples, with intrinsic metal value providing a meaningful floor to secondary-market pricing. The Arabic numeral concentric-circle dial found on the 178238 has gathered a dedicated following among collectors who seek the Datejust's inherent quality without the predictability of conventional dial treatments. This is a reference for the buyer who appreciates subtle distinction — a watch that rewards close inspection and reveals its character gradually rather than demanding immediate attention.
