Datejust 31 Rose Gold / Diamond / Rose - Roman / Oyster

About This Watch

The Rolex Datejust 31, in its 278285rbr-0028 iteration, embodies a refined balance of tradition and modernity, distinguished by its rose gold case and a bezel adorned with meticulously set gemstones that catch light with quiet sophistication. The dial, a deep rose hue with a sunburst finish, serves as a canvas for the watch’s Roman numeral indexes and slender stick hands, their design echoing the timeless elegance of the Datejust collection, which has graced wrists since 1945. The Oyster case, a hallmark of Rolex’s engineering, ensures durability without compromising the watch’s svelte 31-millimeter profile, while the sapphire crystal protects the dial with unobtrusive clarity. At its heart lies the Caliber 2236, an automatic movement celebrated for its precision and reliability, its performance underscored by the brand’s commitment to in-house innovation. This watch, with its closed case back and 100-meter water resistance, is a testament to Rolex’s mastery of both aesthetics and function. Its presence is understated yet deliberate, suited for those who value heritage and craftsmanship as much as discretion. It is the kind of timepiece that complements a formal evening or a quiet moment of reflection, its allure

In Context

At 31 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 55 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

278285rbr-0028 is one of 13 executions of the 278285rbr base reference. Underneath they are the same watch; what separates this one is a rose sunburst dial and a rose gold case.

The 2236 is the Rolex movement inside more watches in this library than any other: 907, in the 28 mm Lady-Datejust and the 31 mm Datejust 31. It was the first Rolex caliber with a silicon hairspring. Introduced in 2014 in the Pearlmaster 34, it is a 20 mm automatic with a date, 31 jewels, a 55-hour reserve and a beat of 28,800 vph, certified by the COSC and then tested again by Rolex after casing to the Superlative Chronometer tolerance of two seconds a day. Its distinction is the Syloxi hairspring: silicon, immune to magnetism, etched to a patented geometry that keeps the spring concentric in every position, and paired with Paraflex shock absorbers. The larger Rolex calibers kept the Parachrom alloy spring; Syloxi did not reach a men's movement until the 7140 of 2023. The [2236 piece](/blog/the-rolex-2236-the-most-common-movement-in-this-library) sets out that history. In the library it powers 488 [Datejust 31](/brands/rolex/datejust-31) references, the seven-digit 2782xx generation of 2020, 399 [Lady-Datejusts](/brands/rolex/lady-datejust) of the 2791xx generation of 2015, 15 [Pearlmasters](/brands/rolex/pearlmaster) and 5 [Yacht-Master 37s](/brands/rolex/yacht-master). The [2235](/calibers/rolex-2235) is the 48-hour movement it replaced, the [2232](/calibers/rolex-2232) its no-date sibling for the Oyster Perpetual, and the [3235](/calibers/rolex-3235) its counterpart in the 36 mm and 41 mm cases.
