Datejust 31 White Gold Fluted / President / Pink MOP Roman

About This Watch

The Rolex Datejust 31, a timeless icon since its introduction in 1945, finds a striking expression in this white gold iteration, where tradition meets refined elegance. The dial, a soft pink mother-of-pearl, glows with a subtle iridescence that shifts under varying light, its surface adorned with Roman numerals and polished stick hands that emphasize the collection’s enduring link to classic horology. The fluted bezel, a signature feature of the Datejust line, adds a tactile and visual dimension to the case, while the President bracelet—crafted with the same white gold—ensures a seamless fusion of comfort and sophistication. This reference, though discreet in its detailing, carries the weight of a lineage that has defined luxury wristwear for generations. At its core lies the Caliber 2235, a self-winding mechanical movement with a date display, engineered for precision and reliability. Its 100-meter water resistance, paired with a sapphire crystal and closed case back, underscores the balance between everyday practicality and haute horlogerie. The watch’s restrained opulence speaks to those who value understated refinement, making it as suited for a formal evening as it is for quiet moments of contemplation. For the discerning collector or the individual seeking a timepiece that transcends trends, this Datejust 31 is not merely an accessory, but a testament to enduring craftsmanship.

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.

178279-0058 is one of 25 executions of the 178279 base reference. Underneath they are the same watch; what separates this one is a pink dial and a white 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.
