Datejust 31 Yellow Gold Domed / Oyster / MOP Roman

About This Watch

The Rolex Datejust 31, in its 178248-0013 iteration, embodies the enduring elegance of a collection that has defined timeless sophistication since its introduction in 1945. This particular reference marries the brand’s mastery of craftsmanship with a refined aesthetic, featuring a 31-millimeter yellow gold case that tapers subtly into a domed profile, a silhouette both modern and rooted in Rolex’s heritage of precision engineering. The dial, a luminous white mother-of-pearl surface with a sunburst finish, is adorned with Roman numerals and stick hands that exude quiet authority, while the sapphire crystal ensures clarity and durability without compromising the watch’s classic character. The Oyster case, sealed against water up to 100 meters, underscores Rolex’s commitment to resilience without sacrificing the delicate balance of form and function that defines the Datejust lineage. At its heart lies the Caliber 2235, an automatic movement with a date display that operates with the precision and reliability for which Rolex is renowned. The interplay of the dial’s opalescent sheen and the case’s warm yellow gold hue creates a visual harmony that feels both contemporary and timeless, a testament to the brand’s ability

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.

178248-0013 is one of 38 executions of the 178248 base reference. Underneath they are the same watch; what separates this one is a white sunburst dial and a yellow gold 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.
