Rolex Datejust 31 White Gold — Fluted Bezel Blue Roman Dial | Ref. 178279

Reference 178279 is the 31 mm Datejust in solid 18ct white gold with a fluted bezel and a blue dial set with Roman hour numerals — a configuration that distils the Datejust's founding aesthetic into a mid-size format with quietly sophisticated colour and material choices. Blue Roman dials on white gold cases create an inherent visual harmony, the cool tones of the metal and the dial reinforcing each other in a way that wears formally without the overt jewellery statement of a diamond-set bezel.

Calibre 2235 powers this reference — Rolex's self-winding movement designed specifically for the 31 mm case family, incorporating a Glucydur beryllium balance wheel and a Breguet overcoil hairspring for enhanced precision and shock resistance. The white gold fluted bezel, machined from solid precious metal rather than applied as a decorative element, serves a functional tradition dating to the original Datejust as a tool for tightening the case back. The jubilee bracelet in 18ct white gold provides the classic five-link suppleness traditionally paired with dress-oriented Datejust variants.

The 31 mm Datejust in white gold occupies firm ground in the secondary market, with Roman dial examples attracting collectors who prize legibility and traditional design language over more ornate dial variants. Reference 178279 represents a previous-generation case with proven movement credentials, offering collectors an entry into all-white-gold Rolex ownership at a price point below newer 278-series equivalents. For buyers seeking a refined daily-wear dress watch in precious metal, few alternatives match this combination of case quality, movement reliability, and lasting aesthetic appeal.
