Datejust 31 Yellow Gold / Domed / Butterfly / President

About This Watch

The Rolex Datejust 31, in its Yellow Gold iteration with a domed case and President bracelet, embodies the enduring elegance of a collection first introduced in 1945. This reference, distinguished by its 31mm diameter and 16mm lug width, balances proportion and presence, offering a refined silhouette that feels both contemporary and timeless. The white dial, crafted from mother-of-pearl, glows with a subtle iridescence that shifts under different light, its gloss finish complemented by the absence of indexes, allowing the stick hands to dominate with minimalist precision. The domed sapphire crystal adds a layer of sophistication, while the closed caseback and 100-meter water resistance underscore the watch’s commitment to both aesthetics and practicality. At its heart lies the Caliber 2236, an automatic movement with a 55-hour power reserve, its finishing and performance reflecting Rolex’s mastery of in-house engineering. The butterfly clasp, a hallmark of the President bracelet, ensures a secure yet effortless fit, while the yellow gold case—polished to a mirror-like sheen—exudes quiet authority. This watch is for those who seek distinction without ostentation, a piece suited to moments that demand both discretion and legacy. Whether worn to a gala or tucked beneath a cuff during a business meeting, it speaks to the wearer’s understanding of heritage, craftsmanship, and the quiet confidence of a timepiece that needs no embellishment.

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.

278248-0022 is one of 26 executions of the 278248 base reference. Underneath they are the same watch; what separates this one is a white gloss dial and a yellow 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.
