Datejust 31 Stainless Steel Diamond / Oyster / Silver - Diamond

About This Watch

The Rolex Datejust 31, in its 2020 iteration with a diamond-set white gold bezel and silver sunburst dial, embodies the quiet confidence of a timepiece that has defined elegance for generations. This reference, part of the Datejust collection introduced in 1945, merges enduring design principles with contemporary refinement. The 31mm stainless steel case, paired with a white gold bezel adorned with meticulously set diamonds, creates a juxtaposition of robustness and delicacy that feels both modern and timeless. The silver dial, finished with a sunburst pattern, is enhanced by gem-set indexes and stick hands that emphasize legibility without sacrificing sophistication. The Oyster case, sealed with a screw-down crown and protected by a sapphire crystal, ensures resilience against the elements, while the automatic Caliber 2236—precise, self-winding, and crafted in-house—reflects Rolex’s commitment to mechanical excellence. The Datejust 31’s heritage as a symbol of understated prestige is evident in every detail, from the polished lug ends to the subtle interplay of light on the bezel. Its 100-meter water resistance and 12-power reserve further underscore its practicality, though it is the watch’s ability to transition seamlessly from boardroom to evening event that cements its appeal. For those who value heritage without ostentation, this timepiece is a testament to the enduring language of horology. It suits the individual who prefers quiet distinction, whether in the pursuit of professional milestones or the quiet moments that define a life of refinement.

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.

278384RBR-0033 is one of 34 executions of the 278384RBR base reference. Underneath they are the same watch; what separates this one is a silver sunburst dial and a white gold, stainless steel case. Introduced in 2020.

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.

906 other watches in the library run the Rolex 2236.
