Datejust 31 Stainless Steel Diamond / Jubilee / Pink - Roman

About This Watch

The Rolex Datejust 31, in its 178384-0009 iteration, marries the enduring elegance of the Datejust collection with a distinctive interplay of materials and color. The case, a harmonious blend of stainless steel and white gold, frames a dial that defies convention with its soft, blush-pink hue—a choice that evokes both warmth and restraint. Roman numerals, rendered in a crisp, legible script, anchor the dial’s design, while slender stick hands trace their path with quiet precision. The Jubilee bracelet, a hallmark of the Datejust since its 1945 debut, adds a layer of sophistication through its refined, five-link construction, ensuring both comfort and a timeless silhouette. The sapphire crystal, paired with a closed case back, underscores the watch’s commitment to durability without compromising the allure of its hidden mechanics. At its core, the Datejust 31 houses the Calibre 2235, a self-winding movement distinguished by its reliability and the inclusion of a date display at 3 o’clock, a feature that has become synonymous with the Datejust’s identity. The movement’s finishing, though unobtrusive, reflects Rolex’s meticulous attention to detail, from the perlage on the oscillating weight to the precise gear trains that ensure consistent performance. This watch, with its balanced proportions and restrained opulence, is a testament to the Datejust’s role as a bridge between tradition and modernity. Suited for those who value understated refinement, the Datejust 31 in this configuration is an ideal companion for occasions that demand both presence and discretion—whether in the boardroom, at a gala, or during the quiet moments of daily life. It speaks to the wearer’s discernment, offering a legacy of craftsmanship that transcends trends.

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.

178384-0009 is one of 52 executions of the 178384 base reference. Underneath they are the same watch; what separates this one is a pink dial and a white 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.
