Datejust 31 Stainless Steel / Yellow Gold / Diamond / Grey - Diamond / Jubilee

About This Watch

The Rolex Datejust 31, in its 278383RBR-0022 iteration, embodies the quiet precision of a timepiece that balances tradition with contemporary refinement. This reference distinguishes itself through a harmonious interplay of materials: a 31mm case combining polished stainless steel and yellow gold, accented with a single row of diamonds along the bezel. The dial, a deep, matte grey with a sunburst finish, serves as a minimalist canvas for gem-set indexes that catch light with subtle elegance. Stick hands, crisp and legible, complement the dial’s understated sophistication, while the Jubilee bracelet—characteristic of the Datejust lineage—adds a layer of classic versatility. Since its introduction in 1945, the Datejust collection has remained a benchmark for enduring design, and this model honors that legacy with modern technical precision. The Caliber 2236 automatic movement, visible through the closed caseback, ensures reliable performance with a 55-hour power reserve, a testament to Rolex’s mastery of in-house engineering. The case’s 100-meter water resistance and sapphire crystal further underscore its balance of practicality and luxury. This watch is for the discerning individual who values subtlety over ostentation, a piece suited to both formal occasions and moments of quiet distinction. It speaks to those who recognize that true luxury lies not in excess, but in the meticulous execution of detail—a philosophy that has defined Rolex for over a century.

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.

278383RBR-0022 is one of 24 executions of the 278383RBR base reference. Underneath they are the same watch; what separates this one is a grey sunburst dial and a yellow gold, stainless steel 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.
