Datejust 31 Rose Gold / Diamond / Rose / Oyster

About This Watch

The Rolex Datejust 31 in rose gold, with its gem-set bezel and sunburst rose dial, embodies the enduring elegance of a collection first introduced in 1945. This reference, distinguished by its 31mm case and 16mm lug width, strikes a balance between the classic proportions of its predecessors and the modern sensibilities of contemporary horology. The dial’s warm rose hue, paired with stick indexes and hands, exudes understated sophistication, while the bezel’s diamond-set arrangement adds a subtle yet unmistakable touch of opulence. The Oyster case, sealed with a closed back and protected by a sapphire crystal, ensures both durability and clarity, reflecting Rolex’s commitment to precision engineering. As a member of the Datejust family, it carries forward the legacy of a timepiece that has long symbolized the intersection of craftsmanship and accessibility within the luxury watch realm. At its heart lies the Caliber 2236, a self-winding movement certified as a chronometer for its accuracy and reliability. This mechanical marvel, with its 288 components and 28,800 vibrations per hour, underscores Rolex’s mastery in integrating performance with refinement. The watch’s 100-meter water resistance and Oyster case construction further highlight its resilience, a testament to

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-0017 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.
