Datejust 31 Stainless Steel Domed / Jubilee / Pink Roman

About This Watch

The Rolex Datejust 31 has long stood as a paragon of timeless elegance, and the pink dial iteration within this collection exemplifies the quiet sophistication that defines its legacy. Introduced in the 1940s as a response to the demand for a self-winding chronometer-equipped watch, the Datejust remains an enduring symbol of horological craftsmanship. This particular model, with its 31mm stainless steel case and domed profile, balances proportion and presence, while the Jubilee bracelet—characterized by its five-link design—offers both comfort and a sense of refined continuity. The dial, a striking shade of pink, is finished with a sunburst texture that deepens the hue’s complexity under varying light, complemented by stick hands and pink Roman numerals that echo the collection’s enduring aesthetic language. At its core, the watch houses the Caliber 2235, a self-winding movement celebrated for its precision and reliability. Certified as a chronometer, it ensures accuracy within strict tolerances, a testament to Rolex’s unwavering commitment to technical excellence. The sapphire crystal, paired with a water resistance rating of 100 meters, underscores the watch’s practicality without compromising its elegance. This timepiece is suited for those who value understated distinction—individuals who seek a watch that transcends trends, serving as both a daily companion and a statement of enduring taste. Its presence is unobtrusive yet unmistakable, ideal for moments that demand both formality and quiet confidence.

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.

178240-0033 is one of 24 executions of the 178240 base reference. Underneath they are the same watch; what separates this one is a pink sunburst dial and a stainless steel case.

+ 15 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.
