Datejust 31 Yellow Gold Domed / President / Silver Computer

About This Watch

The Rolex Datejust 31, in its 178248-0031 iteration, embodies the quiet authority of a timepiece that has defined elegance for generations. With a 31mm yellow gold case, its domed profile and polished edges evoke the enduring proportions of the Datejust collection, first introduced in 1945 as a symbol of accessible luxury. The dial, a luminous silver canvas, is adorned with gem-set indexes that catch light with subtle precision, while stick hands trace their path with minimalist clarity. Paired with a president bracelet—its three-link design a hallmark of Rolex’s commitment to comfort and sophistication—the watch balances tradition with a modern sensibility. The sapphire crystal, paired with a closed case back, ensures both durability and a seamless silhouette, while the 100-meter water resistance underscores its practicality without compromising its refined purpose. At its heart lies the Calibre 2235, an automatic movement distinguished by its 38-hour power reserve and a date display that shifts with the quiet efficiency of a well-rehearsed ritual. This mechanical precision, coupled with the watch’s unobtrusive presence, speaks to Rolex’s mastery of marrying technical innovation with timeless design. The Datejust 31’s restrained opulence makes it a natural companion for those who value understated distinction—whether in

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.

178248-0031 is one of 38 executions of the 178248 base reference. Underneath they are the same watch; what separates this one is a silver 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.
