Rolex Datejust 31 Yellow Gold — Mother-of-Pearl Diamond Dial Oyster | Ref. 278248

Reference 278248 is the Datejust 31 in solid 18ct yellow gold with a mother-of-pearl diamond dial — a specification where natural material artistry and Rolex engineering meet in the mid-size format. Mother-of-pearl dials, sourced specifically from gold or white lip oysters and sliced to a carefully controlled thickness, exhibit an iridescent quality unique among watch dial materials. The surface shifts between warm cream, pale champagne, and soft silver as ambient light and viewing angle change, creating a dial that is never identical to itself from one moment to the next.

Diamond hour markers are set directly into the mother-of-pearl surface by Rolex's lapidary team, each stone individually positioned for consistency of height and orientation. Against the inherently variable surface of natural mother-of-pearl, achieving this consistency requires skill and time that machine production cannot replicate. The solid yellow gold case adds appropriate warmth to the palette, the metal's characteristic colour amplifying the pearl's warm tones. The Oyster bracelet in solid yellow gold provides a sport-capable alternative to the President bracelet.

Calibre 2235 powers this reference — Rolex's dedicated mid-size Lady-Datejust movement — providing the reliability and serviceability expected of a watch in regular wear. The combination of natural material dial, precious metal case, and proven movement architecture makes the 278248 an exceptional value proposition in the gold Lady-Datejust category, particularly for buyers who appreciate natural material dials over lacquer or enamel alternatives.
