Rolex Datejust 31 Yellow Rolesor — Mother-of-Pearl Roman Dial | Ref. 178273

The Datejust 31 ref. 178273 in Yellow Rolesor unites the warmth of 18ct yellow gold with the practicality of Oystersteel in a combination that has endured as one of Rolex's most beloved mixed-metal formats. The fluted yellow gold bezel — its cross-hatched engine-turned surface catching light from every angle — crowns an Oyster case of genuine horological heritage. The centrepiece is the luminous mother-of-pearl dial, its natural iridescence shifting between cream, blush, and silver in changing light, framed by Roman numeral hour markers that lend the dial an aristocratic, almost classical character.

Internally, Calibre 2235 — the self-winding movement that served the 31 mm Datejust family with distinction — drives this reference with 28,800 vph precision. The 2235 employs a Glucydur beryllium balance wheel and a Parachrom hairspring in a blue paramagnetic alloy, conferring significant resilience against magnetic fields and mechanical shock. Certified as a Superlative Chronometer by Rolex's in-house testing regime to -2/+2 seconds per day, the movement's performance belies the ornate nature of the case. Water resistance reaches 100 metres via the iconic Twinlock screw-down crown.

Mother-of-pearl dials with Roman numeral indices occupy a distinguished position in the Datejust collector hierarchy — they evoke the watch's mid-century origins while remaining thoroughly contemporary. The Yellow Rolesor case and matching Jubilee bracelet (the bracelet most commonly paired with this reference) deliver a warm, jewellery-forward appearance that transcends trends. For a buyer seeking a Lady Rolex that is at once historically rooted and visually captivating, the ref. 178273 represents an especially nuanced choice.
