Datejust 31 White Gold Diamond / President / Pink Roman

About This Watch

The Rolex Datejust 31, in its 178159-0071 iteration, marries the brand’s enduring legacy with a refined aesthetic that underscores its status as a timeless icon. A white gold case, polished to a luminous sheen, frames a dial of deep, velvety pink—a hue that evokes both warmth and sophistication. The bezel, adorned with meticulously set diamonds, adds a subtle yet unmistakable touch of opulence, while the pink Roman numerals and slender stick hands create a balance between tradition and modern restraint. The President bracelet, with its signature five-link design, ensures a secure and elegant fit, embodying Rolex’s mastery of both function and form. As the flagship model of the Datejust collection, which has defined luxury wristwatches since its 1945 debut, this reference honors decades of innovation while embracing contemporary craftsmanship. Beneath the sapphire crystal lies the Caliber 2235, an automatic movement celebrated for its precision, reliability, and in-house development. Its 31mm diameter—tailored for a more refined silhouette—pairs with a water resistance of 100 meters, ensuring practicality without compromising elegance. The closed case back, though unadorned, speaks to the watch’s focus on understated quality. This timepiece is for those who seek distinction without ostentation, a companion for moments that demand both presence and discretion. Whether worn to a gala or as a quiet statement of achievement, it reflects the quiet confidence of its owner, rooted in heritage and elevated by meticulous 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.

178159-0071 is one of 36 executions of the 178159 base reference. Underneath they are the same watch; what separates this one is a pink 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.
