Datejust 31 Stainless Steel Domed Diamond / Oyster / Pink MOP - Roman

About This Watch

The Rolex Datejust 31, in its 178344-0048 iteration, embodies the quiet authority of a timepiece that has defined elegance for generations. With a pink mother-of-pearl dial, its surface shimmers with a subtle iridescence, a quality inherent to the material’s natural luster. The dial is framed by polished stainless steel indexes shaped into Roman numerals, their crisp edges and refined finish echoing the collection’s longstanding commitment to classicism. The stick hands, slender and precise, trace their lineage to the Datejust’s 1945 debut, when it first introduced the date complication to the wristwatch world—a innovation that remains central to its identity. The domed sapphire crystal, a signature of modern Rolex design, amplifies the dial’s depth while ensuring clarity and durability, a testament to the brand’s relentless pursuit of technical excellence. At the heart of the watch lies the Caliber 2235, an automatic movement with a 70-hour power reserve, its precision and reliability underscored by Rolex’s in-house engineering. The Oyster case, sealed against water and dust, reflects the brand’s heritage of robustness without sacrificing refinement. The 31mm diameter strikes a balance between intimacy and presence, making it a versatile companion for both formal occasions and moments of quiet significance. This watch is for the individual who values understated sophistication, whose discernment lies not in ostentation but in the quiet confidence of a timepiece that has stood the test of time. It suits the man or woman who wears heritage as a statement

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.

178344-0048 is one of 51 executions of the 178344 base reference. Underneath they are the same watch; what separates this one is a pink 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.
