Datejust 31 Rolesor Everose Domed Diamond / Oyster / White Diamond

About This Watch

The Rolex Datejust 31 178341-0037 stands apart for its seamless fusion of traditional craftsmanship and modern refinement, embodying the enduring legacy of the Datejust collection, which has defined elegance on the wrist since 1945. The dial, a pristine white expanse, is framed by gem-set indexes that catch light with quiet sophistication, their subtle sparkle complementing the everose gold of the case. This Rolesor construction—rose gold and stainless steel—exudes a balanced warmth, while the domed sapphire crystal adds a layer of contemporary sophistication. The 31mm case, modest in proportion yet commanding in presence, is a testament to Rolex’s mastery of proportion and material harmony, ensuring the watch sits comfortably on a variety of wrists. At its core, the watch houses the Caliber 2235, a self-winding movement with a certified chronometer rating, ensuring precision and reliability. Its Parachrom balance spring and Paraflex shock absorbers underscore Rolex’s commitment to resilience without compromise. The closed caseback, paired with the Oyster case’s water resistance to 100 meters, reinforces the brand’s reputation for durability. This timepiece is for those who value understated luxury—a collector seeking a versatile companion for both formal engagements and everyday moments. Its restrained opulence and timeless design make it a quiet declaration of discernment, suited to those who prefer their horological statements to speak through craftsmanship rather than volume.

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.

178341-0037 is one of 34 executions of the 178341 base reference. Underneath they are the same watch; what separates this one is a white 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.
