Datejust 31 Stainless Steel Diamond / Jubilee / Blue - Diamond

About This Watch

The Rolex Datejust 31, in its 178384-0046 iteration, exemplifies the brand’s mastery of balancing tradition with refined modernity. This particular reference distinguishes itself through a harmonious interplay of materials: a case combining stainless steel and white gold, accented with a bezel set with diamonds that catch light with quiet precision. The dial, a deep, even blue, serves as a canvas for gem-set indexes that add a subtle yet deliberate touch of opulence, while stick hands provide clarity and elegance. The Jubilee bracelet, a hallmark of the Datejust collection since its 1945 debut, wraps the wrist with a signature comfort and sophistication that has defined the model’s enduring appeal. At its core, the watch houses the Caliber 2235, an automatic movement distinguished by its reliability and the inclusion of a Parachrom balance spring, ensuring resilience against shocks and magnetic interference. The sapphire crystal, paired with a closed case back, underscores Rolex’s commitment to durability without compromising the watch’s timeless aesthetic. Measuring 31mm in diameter, the case strikes a balance between presence and discretion, a hallmark of the Datejust’s heritage as a versatile icon. This timepiece is for the individual who values understated refinement, seeking a companion for both formal occasions and the quiet moments of daily life. It is not a statement, but a testament to the quiet confidence of those who understand the weight of legacy in design.

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.

178384-0046 is one of 52 executions of the 178384 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.
