Rolex Datejust 31 Gold — Silver Diamond Dial, Fluted Bezel | Ref. 278275

Among the modern Datejust 31 references, 278275 stands out as a full 18 ct gold proposition — a rarity in the mid-size category where Rolesor combinations dominate. The fluted bezel, one of the most enduring design elements in the Rolex canon, is rendered here in solid gold, interacting with light in the deep, warm manner that only a precious-metal case can achieve. The silver dial set with diamond hour markers reinforces the dressy intent while maintaining legibility.

At the heart of the 278275 is Calibre 2236, the movement Rolex introduced specifically for the new-generation Datejust 31. The 2236 incorporates the Syloxi silicon hairspring — a proprietary Rolex development offering superior isochronism and antimagnetic properties — and an improved Perpetual rotor geometry. Housed in a 31 mm Oyster case crafted entirely in 18 ct gold, the watch is rated to 100 metres water resistance. The Jubilee bracelet in matching gold sits flush and supple on the wrist, a testament to Rolex's in-house bracelet manufacturing.

An all-gold Datejust 31 with diamonds occupies rarefied territory in the secondary market. These references attract collectors consolidating around fewer, higher-quality pieces, as well as buyers seeking a daily-wear dress watch with genuine intrinsic metal value. Production volumes are inherently constrained relative to steel or Rolesor variants, which underpins long-term price stability. For a buyer seeking the complete Datejust expression in the 31 mm format, 278275 represents the pinnacle of the series.
