Datejust 31 Rolesor Everose Domed Diamond / Oyster / MOP Roman

About This Watch

The Rolex Datejust 31, in its 178341-0014 iteration, exemplifies the quiet authority of a timepiece that balances heritage with contemporary refinement. A member of the Datejust collection—a lineage established in 1945 as the first self-winding waterproof chronometer wristwatch—this model reimagines the collection’s enduring appeal through a harmonious interplay of materials and design. The case, crafted in Rolesor, a blend of 18ct yellow gold and Everose gold, is framed by a domed bezel set with a subtle yet striking arrangement of diamonds, their presence understated but deliberate. The dial, a luminous white mother-of-pearl, is adorned with Roman numerals and stick hands, their minimalist geometry amplifying the watch’s elegance while ensuring legibility. The sapphire crystal, paired with a closed caseback, underscores the Oyster case’s robustness, a hallmark of Rolex’s engineering since 1926. At its heart lies the Caliber 2235, an automatic movement that marries precision with reliability, featuring a Parachrom blue balance spring and a Côtes de Genève finish visible through the caseback. This technical sophistication is married to the Datejust 31’s svelte proportions: a 31mm diameter and 16mm lug width that render it both wearable and poised. The watch’s water resistance to 100 meters, while not its primary function, speaks to its versatility. Suited for those who value discretion as much as craftsmanship, this watch is the quiet companion of discerning individuals who seek a timepiece that transcends trends. It is for the professional, the connoisseur,

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.

178341-0014 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.
