Datejust 31 Rolesor Everose Domed Diamond / Oyster / MOP Roman

About This Watch

The Rolex Datejust 31, in its Rolesor iteration with an Everose gold case and domed diamond bezel, represents a masterful synthesis of enduring design and refined materials. The dial, a luminous mother-of-pearl surface, is framed by elegant Roman numerals and paired with slender stick hands that enhance legibility without sacrificing understated sophistication. The 31mm case, a modern reinterpretation of the Datejust’s 1945 debut, balances proportion and presence, its polished Everose gold reflecting a warm, enduring patina. The domed diamond bezel adds a subtle yet distinctive touch, elevating the watch’s presence while maintaining the Datejust’s hallmark of timeless elegance. At its core, the 178341-0012 is powered by Rolex’s in-house Caliber 2235, a self-winding movement celebrated for its precision, reliability, and the inclusion of a Parachrom blue balance spring, which ensures resilience against magnetic interference and temperature fluctuations. The closed case back and sapphire crystal further underscore the watch’s commitment to durability and clarity, while the water resistance of 100 meters speaks to its practicality without compromising its status as a luxury timepiece. This watch is for the discerning individual who values heritage, craftsmanship, and quiet distinction. It suits formal occasions with its classic silhouette and subtle opulence, yet its versatility makes it equally at home in moments of quiet reflection or discreet sophistication.

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.

178341-0012 is one of 34 executions of the 178341 base reference. Underneath they are the same watch; what separates this one is a white dial.

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.
