Datejust 31 Rolesor Everose Domed Diamond / Oyster / Purple Roman

About This Watch

The Rolex Datejust 31, in its 178341-0011 iteration, stands apart through its harmonious fusion of the brand’s signature Rolesor Everose — a proprietary alloy of 18ct gold and stainless steel — with a dial that defies convention. The purple hue, a rare and deliberate choice, evokes the depth of amethyst or the quiet intensity of twilight, rendered with a matte finish that resists glare while maintaining a subtle sheen. Roman numerals, rendered in a contrasting tone, anchor the dial’s elegance, while the stick hands trace their lineage to the Datejust’s 1945 debut, when the model first introduced the date complication in a round case. The domed diamond indexes, set with precision, add a tactile refinement that complements the Oyster case’s enduring durability, a hallmark of Rolex’s engineering since 1926. At its core, the watch houses the Caliber 2235, a self-winding movement distinguished by its 288 components, 28 jewels, and a 70-hour power reserve. Its silicium balance spring and Parachrom blue hairspring ensure resilience against magnetic fields and temperature fluctuations, reflecting Rolex’s relentless pursuit of precision. The closed caseback, paired with a sapphire crystal, reinforces the watch’s robustness without compromising its visual allure. This timepiece is for the discerning individual who seeks a symbol of quiet distinction — a companion to both formal occasions and the quiet moments that define a life of substance. It is not a statement, but a testament.

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.

178341-0011 is one of 34 executions of the 178341 base reference. Underneath they are the same watch; what separates this one is a purple dial and a rose gold, stainless steel case.

+ 25 more variants in this family.

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.
