Datejust 31 Stainless Steel Domed / Pink / Pink

About This Watch

The Rolex Datejust 31, in its 178240-0028 iteration, offers a refined reinterpretation of the collection’s enduring legacy, blending timeless elegance with a contemporary flourish. The dial’s deep pink hue, rendered in a sunburst finish, exudes quiet sophistication, its radiance subtly amplified by the contrast of polished stick indexes and hands. Encased in stainless steel with a gently domed profile, the watch retains the Datejust’s signature balance of robustness and refinement, a hallmark of the collection since its introduction in 1945. The 31mm diameter ensures a modern, proportionate presence on the wrist, while the sapphire crystal and 100-meter water resistance underscore its practicality without compromising its stature. At the heart of the watch lies the Caliber 2235, a self-winding movement distinguished by its precision engineering and reliability—a testament to Rolex’s mastery of horology. The closed case back, though unadorned, speaks to the brand’s commitment to discretion and durability. This iteration of the Datejust 31, with its restrained yet striking color palette, appeals to those who seek a timepiece that commands respect through subtlety rather than ostentation. It is a watch for the discerning individual who values heritage, craftsmanship, and the quiet confidence of a design that transcends trends. Whether worn in formal settings or as a companion through daily life, it embodies the quiet authority of a piece that needs no embellishment to assert its place in the world of fine watches.

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.

178240-0028 is one of 24 executions of the 178240 base reference. Underneath they are the same watch; what separates this one is a pink sunburst dial and a stainless steel case.

+ 15 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.
