Datejust 31 Yellow Gold Diamond / Oyster / Silver

About This Watch

The Rolex Datejust 31, a perennial symbol of understated elegance, finds a striking expression in this yellow gold model with a gem-set bezel. The 31-millimeter case, crafted in 18ct yellow gold, exudes warmth and refinement, while the bezel’s meticulously arranged diamonds add a touch of discreet opulence. The dial, a luminous silver tone, is adorned with stick indexes and hands that reflect the collection’s enduring commitment to clarity and precision. This iteration of the Datejust 31, with its balanced proportions and timeless design, bridges the legacy of the original 1945 model and contemporary horological innovation. At its core, the watch houses the Caliber 2235, a self-winding movement featuring a Parachrom blue balance spring and a Paramagnetic blue hour indicator. These technical nuances ensure exceptional accuracy and resilience, hallmarks of Rolex’s engineering prowess. The sapphire crystal, paired with a water resistance of 100 meters, underscores the watch’s practicality without compromising its aesthetic purity. This timepiece is for the discerning individual who values heritage, craftsmanship, and subtlety. It suits occasions where presence speaks louder than volume—whether in a boardroom, at a gala, or during a quiet moment of reflection. The Datejust 31, in its enduring form, remains a testament to the quiet confidence of those who wear it.

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.

178288-0083 is one of 38 executions of the 178288 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.
