Rolex Datejust 31 Yellow Rolesor — Silver Jubilee Diamond Dial | Ref. 178243

Reference 178243 presents the Datejust 31 in one of Rolex's most enduring two-tone configurations — Yellow Rolesor, the marriage of Oystersteel and 18ct yellow gold that has defined the Datejust's broader appeal since the 1970s. The 31 mm case bears the gold-fluted bezel characteristic of the Rolesor aesthetic, while the silver dial with Jubilee diamond hour markers introduces a sparkling counterpoint to the warm gold tones. The Jubilee bracelet, with its distinctive five-piece link construction, offers both comfort and visual harmony with the case proportions.

Powered by the Calibre 2235, this Datejust 31 benefits from Rolex's Parachrom hairspring — an in-house alloy of niobium and zirconium offering superior resistance to magnetic fields and mechanical shocks. The 2235 self-winding movement, oscillating at 28,800 vph, achieves Superlative Chronometer certification with a daily rate accuracy of ±2 seconds. The Oyster case construction, with its screw-down Twinlock crown and monobloc middle case, maintains water resistance to 100 metres.

The silver diamond dial on a Yellow Rolesor case is a classically versatile combination — the silver dial provides neutral clarity that complements the warmth of the gold without competing, while the diamond indexes elevate the ensemble from everyday tool watch to statement piece. In the collector community, the 178243 is valued for this precise balance: unmistakably a jewel, yet never ostentatious. The 178xxx series Datejust 31 has developed a loyal following among those who prize this proportional and aesthetic sweet spot, and well-presented examples retain value reliably.
