Datejust 31 Rolesor Everose Fluted / Oyster / Purple Roman

About This Watch

The Rolex Datejust 31, in its Rolesor iteration with a distinctive purple dial, embodies a rare convergence of heritage and innovation. This model, part of the Datejust collection’s enduring legacy since 1945, marries the brand’s signature fluted bezel with a contemporary color palette. The case, a harmonious blend of 18ct rose gold and stainless steel, frames a dial that defies convention—its deep, almost iridescent purple hue evokes both sophistication and quiet individuality. The Roman numerals, rendered in a crisp, legible font, and the slender stick hands contribute to a balanced composition that feels both timeless and modern. The Oyster case, paired with a sapphire crystal and a closed case back, ensures resilience without compromising the watch’s elegant silhouette. At its core lies the Caliber 2235, a self-winding movement with a certified chronometer rating, reflecting Rolex’s commitment to precision. The 31mm diameter, a deliberate nod to the collection’s evolution from larger, more robust designs, ensures the watch remains discreet yet commanding on the wrist. Its 100-meter water resistance and the meticulous finishing of the movement’s components underscore the

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.

178271-0076 is one of 31 executions of the 178271 base reference. Underneath they are the same watch; what separates this one is a purple 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.
