Rolex Datejust 31 White Gold — Mother-of-Pearl Roman Dial, Fluted Bezel | Ref. 178279

Reference 178279 presents the Datejust 31 in a configuration that privileges jewellery-quality refinement: an 18-carat white gold case and fluted bezel frame a mother-of-pearl dial with Roman numeral hour markers, creating a timepiece that reads simultaneously as a horological instrument and an objet de luxe. The 31 mm case occupies the ideal middle ground — more presence than the 28 mm Lady-Datejust, yet retaining the delicacy that distinguishes the mid-size from the full 36 mm reference.

The 178279 is powered by Calibre 2235, the movement platform that underpinned Rolex's mid-size Datejust production prior to the introduction of the silicon-based 2236. The 2235 features a Parachrom hairspring and bidirectional automatic winding with a 48-hour power reserve, delivering the same movement philosophy and chronometric standards as Rolex's larger calibres in a more compact architecture. White gold, with its cool, mirror-bright character, amplifies the iridescent quality of the mother-of-pearl dial — the interplay of precious metal and organic material is one of Rolex's most successful aesthetic dialogues.

Roman numerals on a mother-of-pearl dial occupy a specific collector niche within the Datejust family: they elevate the piece from sports-adjacent dress watch to unambiguous statement of classical elegance. The 178279 in white gold represents a commitment to purity of form — no diamond set stones, no colour contrast, simply the inherent beauty of its materials working in concert. An exemplary choice for the collector whose taste runs toward refined restraint.
