Datejust 31 Stainless Steel / Yellow Gold / Diamond / Champagne / Jubilee

About This Watch

The Rolex Datejust 31, in its 278383RBR-0014 iteration, marries the brand’s enduring legacy of horological excellence with a refined interplay of materials and design. This particular reference stands out for its harmonious blend of stainless steel and yellow gold, a pairing that underscores Rolex’s mastery in metallurgy and craftsmanship. The champagne dial, finished with a sunburst pattern, exudes a quiet sophistication, its warm hue complemented by the subtle contrast of applied stick indexes and dot markers. The hands, also in stick form, trace the dial’s surface with precision, while the sapphire crystal ensures clarity and durability. The Jubilee bracelet, a hallmark of the Datejust collection since its 1945 debut, adds a touch of timeless elegance, its five-link design both comfortable and emblematic of Rolex’s commitment to wearable luxury. At the heart of this watch lies the Caliber

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-0014 is one of 24 executions of the 278383RBR base reference. Underneath they are the same watch; what separates this one is a champagne 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.
