Datejust 31 Yellow Gold Diamond / President / MOP

About This Watch

The Rolex Datejust 31 has long been a benchmark of timeless elegance, and the 178158-0008 exemplifies the collection’s enduring appeal with a refined balance of tradition and meticulous craftsmanship. This iteration marries the enduring prestige of yellow gold with a dial that evokes quiet sophistication: a white mother-of-pearl surface, its iridescent sheen subtly enhanced by gem-set indexes and a bezel that catches light with understated brilliance. The case’s warm hue, paired with the President bracelet’s polished links, creates a harmony of materials that feels both classic and contemporary. The dial’s simplicity is its strength, allowing the interplay of light across the gemstones and the texture of the mother-of-pearl to become the focal point, a testament to Rolex’s mastery of detail. At its heart lies the Caliber 2235, an automatic movement distinguished by its precision engineering and reliability—a hallmark of Rolex’s commitment to horological excellence. With 31 jewels and 288 components, it ensures unwavering performance, while the sapphire crystal and 100-meter water resistance underscore the watch’s durability without compromising its aesthetic restraint. The Datejust 31’s heritage, first introduced in 1945 as a response to the demand for a self-winding chronometer with a date display, is subtly honored here through its uncluttered design and enduring relevance. This watch is for those who value discretion as much as distinction, a piece suited to moments that demand both presence and poise—whether in the boardroom, at a gala, or on the wrist of someone who understands that true luxury lies in the quiet confidence of a

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.

178158-0008 is one of 38 executions of the 178158 base reference. Underneath they are the same watch; what separates this one is a white 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.
