Datejust 31 White Gold Diamond / President / Blue Roman

About This Watch

The Rolex Datejust 31 embodies the enduring legacy of a collection that has defined luxury timekeeping since its introduction in 1945. This particular iteration, distinguished by its white gold case and diamond-set bezel, merges classical elegance with meticulous craftsmanship. The dial, a pristine white canvas, is adorned with blue Roman numerals that echo the timeless aesthetic of early Datejust models, while stick hands provide a clean, legible contrast. The sapphire crystal, paired with a closed case back, ensures both durability and a seamless presentation of the watch’s refined silhouette. At 31 millimeters in diameter, the case strikes a balance between presence and subtlety, its 16-millimeter lug width enhancing the wearability of a timepiece designed for both formal and everyday occasions. Powering this watch is the Caliber 2235, an automatic movement renowned for its precision and reliability, featuring a Parachrom blue balance spring and a Côtes de Genève finish that underscores Rolex’s commitment to horological excellence. The President bracelet, with its polished white gold links, complements the case’s opulence, offering a secure yet comfortable fit. This watch is for the discerning individual who values heritage, understated sophistication, and the quiet confidence of a timepiece that requires no introduction. It suits moments that demand both presence and restraint—a gala, a boardroom, or simply a quiet afternoon when the weight of tradition feels most meaningful.

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.

178159-0070 is one of 36 executions of the 178159 base reference. Underneath they are the same watch; what separates this one is a white 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.
