Datejust 31 Stainless Steel Fluted / Jubilee / Blue - Diamond

About This Watch

The Rolex Datejust 31, in its iteration with a blue dial and gem-set indexes, embodies the quiet mastery of a design that has endured since its introduction in 1945. This particular model, distinguished by its combination of stainless steel and white gold, marries the brand’s legacy of robust construction with a touch of refined opulence. The fluted bezel, a hallmark of the Datejust collection, frames a dial that is both striking and deliberate in its restraint—a deep blue hue that evokes the timeless appeal of the ocean, accented by diamond-set hour markers that catch light with subtle precision. The stick hands, paired with a date window at the 3 o’clock position, ensure legibility without sacrificing elegance, while the Jubilee bracelet offers a balance of comfort and sophistication, its five links a nod to the collection’s enduring design language. At the heart of the watch lies the Caliber 2235, an automatic movement that exemplifies Rolex’s commitment to in-house engineering. Certified as a chronometer, it delivers exceptional accuracy and a power reserve of approximately 55 hours, underscoring the brand’s fusion of tradition and technical innovation. The sapphire crystal, paired with a closed case back, protects the mechanism while emphasizing the watch’s durability—a quality that has long defined Rolex’s reputation. This timepiece is for those who value understated distinction, where heritage and craftsmanship are worn

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.

178274-0048 is one of 52 executions of the 178274 base reference. Underneath they are the same watch; what separates this one is a blue dial and a white gold, stainless steel 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.
