Datejust 31 Rolesor Everose Domed Diamond / Oyster / Black Diamond

About This Watch

The Rolex Datejust 31, in its 178341-0054 iteration, marries the enduring elegance of the Datejust collection with a contemporary reinterpretation of luxury. This reference stands apart through its use of Rolesor, a signature alloy of 18ct rose gold and stainless steel, which lends the case a refined warmth while preserving the robustness expected of a Rolex. The dial, a deep black with a sunburst finish, serves as a striking counterpoint to the gem-set indexes, each diamond meticulously positioned to enhance legibility without overwhelming the eye. The domed sapphire crystal adds a subtle three-dimensionality, a nod to the Datejust’s original 1945 design while embracing modern horological craftsmanship. At its core, the watch houses the Caliber 2235, an automatic movement distinguished by its precise chronometry and the inclusion of a date display that operates with seamless smoothness. The 31mm case diameter, paired with a lug width of 16mm, ensures a balanced presence on the wrist, a testament to Rolex’s mastery of proportion. The Oyster caseback, sealed against the elements, underscores the watch’s reliability—a hallmark of the brand since its inception. This timepiece is for the individual who values understated sophistication and the quiet confidence of a heritage steeped in precision. It suits occasions where discretion is as important as distinction, whether in the boardroom, at a gala, or as a companion to moments of quiet reflection. For collectors, it is a testament to Rolex’s ability to evolve while honoring its legacy.

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. 48 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.

178341-0054 is one of 34 executions of the 178341 base reference. Underneath they are the same watch; what separates this one is a black sunburst dial and a rose gold, stainless steel case.

The 2235 is the small Rolex automatic of the six-digit generation, a 20 mm movement with a date. It carried the Datejust 31 and the 26 mm Lady-Datejust from around 2000 until the 2236 replaced it. It powers 733 watches in this library. It has 31 jewels, a 48-hour reserve and a beat of 28,800 vph, and every one is a COSC chronometer. It is the same architecture as the [2236](/calibers/rolex-2236) that followed, without the silicon Syloxi hairspring and with seven hours less reserve; the [2236 piece](/blog/the-rolex-2236-the-most-common-movement-in-this-library) explains what changed. The library finds it almost entirely in the [Datejust 31](/brands/rolex/datejust-31): 682 references, the 1782xx generation, whose 45 base references and hundreds of dial variants make that collection the largest here. The 26 mm [Lady-Datejust](/brands/rolex/lady-datejust) of the 1791xx generation accounts for 29, the [Pearlmaster](/brands/rolex/pearlmaster) 29 mm and 34 mm for 19, and the 35 mm Yacht-Master for 3. A six-digit Datejust 31 reference is a 2235; the seven-digit one is a 2236, as the [reference-number guide](/blog/how-to-read-a-watch-reference-number) explains. The 2231 was its no-date sibling in the Oyster Perpetual, and the [3135](/calibers/rolex-3135) its counterpart in the 36 mm cases.

732 other watches in the library run the Rolex 2235.
