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

About This Watch

The Rolex Datejust 31, in its 278285RBR-0016 iteration, marries the enduring elegance of the Datejust collection with a refined interplay of materials and design. A 31-millimeter rose gold case, polished to a warm luster, frames a brown sunburst dial that exudes understated sophistication. The bezel, adorned with meticulously set gemstones, adds a touch of opulence without overshadowing the dial’s classical appeal, while Roman numeral indexes and slender stick hands reinforce the collection’s heritage of timeless legibility. The President bracelet, with its signature five-link design, ensures a secure yet comfortable fit, blending functionality with the unmistakable craftsmanship of Rolex’s in-house finishing. At the heart of this timepiece lies the Caliber 2236, an automatic movement renowned for its precision and reliability, a testament to Rolex’s unwavering commitment to mechanical excellence. The sapphire crystal, paired with a closed case back, protects the intricate mechanics while emphasizing the watch’s robustness—capable of withstanding 100 meters of water pressure. As one of the most recognizable collections in horology, the Datejust has long symbolized the intersection of tradition and innovation, a legacy upheld here through its balanced proportions and enduring aesthetic. This watch is for the discerning individual who values subtlety as much as prestige, whether marking a milestone or simply elevating everyday moments with quiet distinction. It is a piece that transcends trends, destined to be passed down as a testament to enduring taste.

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-0016 is one of 12 executions of the 278285RBR base reference. Underneath they are the same watch; what separates this one is a brown 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.
