Datejust 31 Rolesor Yellow Diamond / Jubilee / Silver Computer

About This Watch

The Rolex Datejust 31, in its Rolesor iteration of yellow gold and stainless steel, embodies the quiet authority of a timepiece that has defined elegance for generations. This particular reference, distinguished by its gem-set indexes and the refined symmetry of the Jubilee bracelet, merges the heritage of the Datejust collection—introduced in 1945 as a milestone in wearable sophistication—with contemporary craftsmanship. The dial, a luminous silver expanse, is framed by 18k yellow gold hour markers set with diamonds, their subtle sparkle enhancing the watch’s understated opulence. The stick hands, paired with a clean, uncluttered layout, reflect the Datejust’s enduring commitment to legibility and timeless design. At its core, the watch houses the Caliber 2235, an automatic movement celebrated for its precision and reliability, ensuring the Datejust 31 remains as functional as it is refined. The sapphire crystal, paired with a closed case back, safeguards the mechanical poetry within while emphasizing the watch’s robust construction. With a case diameter of 31mm and a water resistance of 100 meters, it balances proportion and practicality, a hallmark of Rolex’s engineering ethos. This watch is for the discerning individual who values heritage without ostentation, a piece suited to moments that demand both presence and restraint—whether in a boardroom, at a gala, or worn as a quiet testament to legacy.

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.

178383-0010 is one of 33 executions of the 178383 base reference. Underneath they are the same watch; what separates this one is a silver dial and a yellow 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.
