Datejust 31 White Gold Fluted / President / Blue Diamond

About This Watch

The Rolex Datejust 31, in its 178279-0033 iteration, embodies the quiet authority of a timepiece that has defined luxury watchmaking for generations. A refined evolution of the Datejust collection, introduced in 1945 as one of the first self-winding wristwatches to display the date on the dial, this model marries the collection’s enduring legacy with contemporary sophistication. The 31-millimeter white gold case, adorned with the iconic fluted bezel, exudes understated elegance, while the president bracelet—crafted with the same precision as the case—offers a seamless blend of comfort and distinction. The dial, a deep, velvety blue, is punctuated by gem-set indexes that catch light with subtle brilliance, and the stick hands trace their path with minimalism that belies their functional precision. At the heart of this watch lies the Caliber 2235, a self-winding movement that exemplifies Rolex’s mastery of horology. Certified as a chronometer, it ensures exceptional accuracy and reliability, while its 72-hour power reserve and Parachrom blue balance spring underscore the brand’s commitment to innovation without compromising tradition. The sapphire crystal, paired with a closed case back, protects the intricate mechanics within, preserving the watch’s integrity against the elements. This timepiece is for the discerning individual who values heritage, craftsmanship, and subtlety. It is suited to moments that demand quiet confidence—whether in boardroom negotiations, formal soirées, or the quiet satisfaction of a well-timed glance at the wrist.

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.

178279-0033 is one of 25 executions of the 178279 base reference. Underneath they are the same watch; what separates this one is a blue dial and a white gold 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.
