Datejust 31 Yellow Gold Domed / President / Silver Roman

About This Watch

The Rolex Datejust 31, in its 178248-0083 iteration, embodies the enduring elegance of a collection that has defined modern horology since its introduction in 1945. This specific reference marries the timeless appeal of yellow gold with a dial that captures the quiet sophistication of a sunburst-finished silver face, its Roman numerals and stick hands rendered in a balance of precision and restraint. The domed case, a subtle nod to the brand’s mid-20th-century design language, is complemented by the President bracelet—a hallmark of Rolex’s commitment to both comfort and distinction—its polished links flowing seamlessly from the case to the concealed clasp. The Datejust’s heritage as a symbol of discreet luxury is evident in every detail, from the sapphire crystal’s unobtrusive clarity to the closed case back that guards the mechanical heart within. At its core lies the Caliber 2235, a self-winding movement that exemplifies Rolex’s mastery of engineering. With a 70-hour power reserve and

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.

178248-0083 is one of 38 executions of the 178248 base reference. Underneath they are the same watch; what separates this one is a silver 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.
