Datejust 31 White Gold Diamond / Jubilee Diamond / Silver Diamond

About This Watch

The Rolex Datejust 31, in its 178159-0055 iteration, embodies the quiet authority of a timepiece that marries tradition with meticulous craftsmanship. A white gold case, polished to a subtle sheen, frames a dial of refined silver, its surface interrupted by gem-set indexes that catch light with restrained elegance. The bezel, encrusted with diamonds, complements the Jubilee bracelet’s hallmark symmetry, a design language first introduced in 1959 and still defining the collection’s enduring appeal. At 31 millimeters in diameter, the watch balances presence with proportion, its sapphire crystal protecting a dial that feels both classic and contemporary. Beneath the caseback lies the Caliber 2235, a self-winding movement with a Parachrom balance spring and a 70-hour power reserve, underscoring Rolex’s commitment to precision engineering. The watch’s water resistance to 100 meters and the durability of its Cerachrom bezel reflect the brand’s mastery of materials, ensuring resilience without compromising aesthetics. The Datejust collection, introduced in 1945, has long symbolized the intersection of horology and legacy, and this reference honors that lineage with understated sophistication. Suited for those who value discretion as much as distinction, the 178159-0055 is a watch for moments that demand quiet confidence—whether in the boardroom, at a gala, or on the wrist of someone who understands that true luxury lies in the marriage of heritage and detail.

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.

178159-0055 is one of 36 executions of the 178159 base reference. Underneath they are the same watch; what separates this one is a silver dial and a white gold case.

+ 27 more variants in this family.

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.
