Rolex Datejust 31 31 mm 278344RBRGRVIDJ Steel/White Gold/Diamonds Grey

The Rolex Datejust is arguably the most iconic and enduring watch in the Rolex catalogue, introduced in 1945 as the first self-winding waterproof wristwatch to display the date in a window on the dial. Over the decades it has evolved through countless dial configurations, case sizes, and material combinations while retaining the unmistakable proportions and the date aperture at three o'clock that made it a legend. The 31mm case size, known as the Datejust 31, occupies a versatile middle ground that suits a wide range of wrists and wearers who prefer a refined, understated diameter without sacrificing presence.

Reference 278344RBRGRVIDJ represents one of the most jewel-forward expressions within the current Datejust 31 family. The case is crafted from Rolex's proprietary Oystersteel, a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polish, blended with polished 18k white gold crown guards and lugs that lend a two-tone sophistication without the full visual weight of a solid precious-metal case. The result is a watch that transitions effortlessly from a boardroom setting to a formal evening event.

The grey dial is a particularly compelling choice in this configuration. Its cool, neutral tone creates a sophisticated backdrop against which the Roman numeral index positioned at six o'clock stands out with architectural clarity — an elegant asymmetry that collectors and enthusiasts recognize as the hallmark of Rolex's Roman VI diamond dial variants. The remaining hour markers are diamond-set, scattering light across the dial in a way that photographs rarely capture fully. Applied Rolex signatures and a cyclops lens magnifying the date window complete a dial that rewards close inspection.

Framing the dial is an 18k white gold domed bezel set with a continuous parade of brilliant-cut diamonds. The domed profile is a classic Datejust form that was popularized in the earliest references of the model and has been revived on high-jewellery variants to great effect. Together with the diamond dial, it means the watch is essentially wrapped in two layers of diamonds, giving the 31mm case a brilliance that punches well above its physical size. The Jubilee bracelet — a five-piece link design first introduced alongside the original 1945 Datejust — completes the watch with the comfortable, supple drape and dressy character that has made it the preferred pairing for jewellery-set Datejust references for generations.

The automatic movement powering this reference delivers the reliable, self-winding performance that Rolex is universally trusted to provide, keeping the watch running with minimal intervention from the wearer. The Oyster case construction, combined with a water resistance rating of 100 meters (330 feet), means that despite its jewellery-level aesthetic this Datejust 31 is built to live on the wrist every day, not simply to rest in a display case. The screw-down crown seals the movement from dust, moisture, and the minor shocks of daily life.
