Rolex Datejust 31 White Gold — White Index Dial, Fluted Bezel | Ref. 178279

Crafted entirely in 18 ct white gold, Reference 178279 presents the Datejust 31 in one of its most formally refined configurations. White gold's cool, silvery tones create a monochromatic visual coherence when paired with the white index dial and the characteristic fluted bezel — a combination that has been central to the Datejust's identity since Rolex introduced the model in 1945 as the world's first self-winding waterproof wristwatch with a date display.

The heart of the watch is Calibre 2235, a self-winding manufacture movement engineered for the mid-size Datejust, featuring a Parachrom hairspring produced from a proprietary paramagnetic alloy developed by Rolex. The Microstella system allows for fine regulation to a precision standard of +2/-2 seconds per day. The all-white-gold Oyster case provides 100 metres of water resistance via the Twinlock double waterproofness system, and the fluted bezel — traditionally the hallmark of a precious-metal Datejust — is machined directly from white gold for tonal unity with the case.

For collectors, a full white gold Datejust 31 in this clean index-and-fluted configuration occupies a distinct niche: it is neither overtly jewelled nor understated, but sits in a well-balanced register appropriate for both formal occasions and daily wear. The all-precious-metal construction ensures strong intrinsic value, while the classic dial layout keeps it perennially relevant across changes in fashion.
