Datejust 31 Rolesor Yellow Domed / Oyster / Silver Roman

About This Watch

The Rolex Datejust 31 in Rolesor yellow gold and stainless steel embodies the quiet authority of a timepiece that has defined elegance for generations. With a 31mm case that balances proportion and presence, its domed yellow gold bezel sits atop a dial that gleams with polished silver, its Roman numeral indexes and slender stick hands forming a composition both classical and refined. The interplay of materials—precious metal and corrosion-resistant steel—reflects the Datejust collection’s enduring legacy, first introduced in 1945 as a symbol of accessibility within luxury. This reference, however, elevates the formula with a subtle yet deliberate choice of tone, where the warmth of yellow gold tempers the dial’s cool luminosity, creating a harmony that feels both timeless and contemporary. At its heart lies the Caliber 2235, an automatic movement with a date display that operates with the precision and reliability expected of a watchmaker whose name is synonymous with horological excellence. The sapphire crystal, paired with a closed case back, ensures the mechanics remain protected while emphasizing the watch’s unpretentious craftsmanship. Its 100-meter water resistance and Oyster case construction further underscore its practicality without compromising its sartorial grace. This watch is for those who value understated distinction, whose tastes are shaped by heritage rather than trend. It suits the boardroom, the gala, or the quiet moments in between—where

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.

178243-0077 is one of 31 executions of the 178243 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.
