Datejust 31 Rose Gold / Diamond / Rose - Diamond / President

About This Watch

The Rolex Datejust 31 Reference 278285RBR-0025 stands as a masterclass in understated elegance, blending the enduring sophistication of the Datejust collection with a refined interplay of materials and craftsmanship. Its rose gold case, polished to a warm luster, frames a dial that mirrors the same hue, its sunburst finish catching light with a subtle, rhythmic depth. The bezel, adorned with meticulously set gemstones, complements the gem-set indexes, creating a harmonious balance between luxury and restraint. This iteration of the Datejust, first introduced in 1945 as a symbol of accessible prestige, retains its signature elegance while embracing a more contemporary silhouette—its 31mm diameter and 16mm lug width offering a modern yet timeless presence on the wrist. At its core lies the Caliber 2236, Rolex’s in-house automatic movement, renowned for its precision, reliability, and the brand’s signature Perpetual rotor. The watch’s sapphire crystal, paired with a closed case back, ensures durability without compromising the clean, unbroken aesthetic of the dial. Encased in a President bracelet—characterized by its seamless, triple-link construction—the piece exudes a quiet authority, designed to accompany the wearer through both formal occasions and the quiet moments of everyday life. This watch is for those who value heritage as much as innovation, seeking a timepiece that speaks in the language of subtlety. It suits the discreet confidence of a collector, the discerning professional, or the individual who prefers their luxury to be measured in craftsmanship rather than ostentation.

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-0025 is one of 12 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.
