Rolex Datejust 31 Yellow Rolesor — Champagne Concentric Circle Arabic Dial | Ref. 178243

Reference 178243 is a mid-generation Datejust 31 in Yellow Rolesor — the pairing of Oystersteel and 18 ct yellow gold — featuring a champagne dial with concentric circle finishing and Arabic numeral hour markers. This dial configuration is among the more traditional and understated in the 31 mm Datejust range: concentric circles give the surface a subtle textile-like depth without introducing gemstones or exotic colour, and the Arabic numerals recall the bold legibility of vintage Rolex dial design.

The 178xxx reference series is powered by Calibre 2235, the predecessor to today's 2236, which itself was a robust and well-regarded movement featuring a Glucydur beryllium balance wheel and a rated accuracy of +/- 2 seconds per day. While the 2235 lacks the Syloxi hairspring of the newer 2236, it is a thoroughly proven calibre with decades of service history across the Rolex ladies' range. The Yellow Rolesor case — with the smooth or fluted bezel configuration and the Jubilee or Oyster bracelet depending on variant — is built to the same Oyster standard as all Rolex sport references, with a screw-down crown providing 100 m water resistance.

For buyers navigating the pre-owned Datejust 31 market, 178xxx references represent mature, proven examples that have stabilised in value. The champagne concentric circle Arabic dial is a versatile, dressy configuration that wears well against both formal and business-casual wardrobes, making the 178243 a sensible choice for someone seeking a daily-wear Rolex without the premium carried by current-generation 278xxx references. Well-maintained examples with original bracelet and documentation continue to find willing buyers across generations.
