Rolex Datejust 31 Gold — Fluted Bezel Rose Index Dial | Ref. 278275

Sitting at the intersection of the Datejust’s classical proportions and Rolex’s mastery of precious metal finishing, reference 278275 presents the 31mm Datejust in an all-gold configuration with the brand’s iconic fluted bezel. The rose index dial — featuring applied hour markers that catch light with distinct warmth — complements the yellow gold case and bracelet to produce a cohesive, luminous aesthetic. At 31mm, this reference occupies the sweet spot between the 28mm Lady-Datejust and the 36mm full-size, offering meaningful wrist coverage while remaining distinctly refined in proportion. The fluted bezel, one of Rolex’s most enduring design signatures since the 1970s, adds texture and catches light from every angle.

Rolex equips the Datejust 31 with movements from the Calibre 2236 family for certain configurations — a manufacture movement developed specifically for mid-size cases, featuring the Syloxi hairspring crafted from silicon, which provides superior resistance to magnetic fields and temperature fluctuations compared to traditional Nivarox springs. The movement oscillates at 28,800 vph and delivers approximately 55 hours of power reserve. Encased in the Oyster case, water resistance extends to 100 metres. The President bracelet or Jubilee bracelet — both exclusive in certain metals to precious metal Datejust references — provide a fitting match for this configuration’s elevated specification.

Reference 278275 is ideally suited for the collector seeking a daily-wear jewellery watch with Rolex’s full horological integrity behind it. Unlike gem-set alternatives in this size, the clean index dial version maintains versatility across formal and casual settings. For those drawn to the mid-size Datejust proposition, it compares favourably against the 278271 Rolesor by offering a uniform gold aesthetic — a purist choice that commands respect in secondary market circles.
