Rolex Datejust Yellow Rolesor — Mother-of-Pearl Diamond Dial | Ref. 178273

Reference 178273 in Yellow Rolesor occupies the Datejust 31 collection with a pairing that has endured as one of the most flattering in Rolex's two-tone vocabulary: stainless steel Oyster architecture combined with 18-carat yellow gold in the fluted bezel, crown, and Jubilee bracelet centre links. The warmth of yellow gold against the cool precision of 904L steel produces a balanced contrast that reads as welcoming rather than showy, making the 178273 equally appropriate for professional and evening contexts. The fluted bezel — machined in solid 18-carat yellow gold across its 44 bevelled ridges — is perhaps the most recognisable decorative element in the Datejust's seven-decade history.

The mother-of-pearl dial with diamond hour markers brings a distinct organic luminosity to the reference. Mother-of-pearl is harvested from mollusk shells and exhibits a structural iridescence — known as orient — that shifts from white to cream to pale rose as the angle of observation changes. Diamond indices set in yellow gold collets catch directional light independently of the nacre background, giving the dial a layered visual depth unavailable in any painted or printed alternative. Calibre 2235 — the movement that preceded the 2236 in the Datejust 31 — drives the date complication via its self-winding bidirectional rotor, certified to COSC standards for chronometric accuracy.

The five-piece link Jubilee bracelet in Yellow Rolesor configuration — steel outer links flanking yellow gold centre links — was originally created for the Datejust's 1945 debut and remains among Rolex's most refined bracelet designs for dressy wear. Its hidden clasp and flush construction sit neatly against the wrist, distributing weight evenly across the articulated links. Water-resistant to 100 metres, the 178273 combines practicality with refined elegance, delivering the full Datejust proposition in a format that rewards equally the first-time buyer and the experienced collector seeking a versatile 31 mm dress watch.
