There is a moment when you hold a vintage Rolex triple calendar moonphase in your hand and realize the dial before you contains more complication than most modern Rolexes ever attempt. The Padellone ref. 8171 is not a Submariner. It is not a Daytona. It is something far stranger and far rarer: a mid-century dress watch with a full calendar and a moonphase, produced by a brand that is famous for simplicity. This is the watch that Rolex never should have made, and that is precisely why collectors cannot stop talking about it.

The nickname “Padellone” comes from Italian collectors, and it translates to “large frying pan.” The name refers to the watch’s 38mm case and its slightly domed dial, which was unusually wide for the late 1940s and early 1950s [citation:1][citation:6]. At a time when most Rolexes were 34mm or smaller, the Padellone was a statement. It was also short-lived. Produced from approximately 1949 to 1952, it is estimated that only 1,000 to 1,200 examples were made, with yellow gold accounting for roughly 350 pieces [citation:2][citation:9]. That scarcity, combined with its unusual complication, has turned the Padellone into one of the most desirable vintage Rolexes in existence.

The Dial: A Calendar And Moon In A Single Display

What makes the Padellone so special is its dial layout. A peripheral date track circles the outer edge, indicated by a central pointer hand. Two apertures sit just under the Rolex crown at 12 o’clock, displaying the day and month. And at 6 o’clock, a small seconds sub-dial houses a moonphase display with a hand-engraved disc. It is a traditional triple calendar with moonphase, executed with the kind of elegance you would expect from Audemars Piguet or Vacheron Constantin—not from the brand that built its reputation on waterproof Oyster cases [citation:1].

The dials were made by Stern Frères, and they are known for aging into warm, creamy patinas that collectors find irresistible [citation:2]. Two dial types exist: the “Type A” with Arabic numerals, made by Beyeler, and the “Type B” with bullet-shaped indexes, made by Stern [citation:11]. Both are beautiful, and both are increasingly difficult to find in original, unrestored condition.

The Case: Not An Oyster

Here is the detail that surprises many collectors. The Padellone is not an Oyster. It has a snap-on caseback rather than a screw-down one, which means it is not waterproof [citation:1][citation:15]. For a brand that had already built its reputation on waterproof cases, this was a deliberate choice. The Padellone was designed as a dress watch, not a tool watch. Its case was made by Favre-Perret in La-Chaux-de-Fonds, and it features separately welded lugs and a three-part construction [citation:2]. The hallmarks on the case band and lugs are an important authentication detail, and collectors pay close attention to them [citation:2].

Inside the watch is the calibre A295 CPL, an automatic movement with a 360-degree rotor and chronometer certification [citation:1]. It is a robust, reliable movement that was developed specifically for this reference. The Padellone was also produced alongside another complicated Rolex, the reference 6062, which featured a screw-down caseback and a 36mm case. Together, these two references represent the only vintage Rolexes produced in serial with a calendar and moonphase [citation:1][citation:6].

Three Perspectives On The Padellone

Viewpoint A (The Vintage Purist): “The Padellone is the most important complicated Rolex ever made. It represents a moment when Rolex was willing to compete with the great dress watch makers of Geneva, and it succeeded. The dial is beautiful, the movement is historically significant, and the rarity is extraordinary. Every serious collector should want one. The fact that it is not an Oyster is not a flaw. It is a reminder that Rolex was once capable of more than just tool watches.”

Viewpoint B (The Skeptic): “It is a beautiful watch, but it is also a problematic one. The snap-on caseback means it is not water-resistant, the movement is difficult to service, and the parts are nearly impossible to find. The prices are astronomical for a watch that most people cannot wear without fear. At auction, a yellow gold Padellone can sell for six figures, and a steel example can go even higher. For that money, you could buy a Patek Philippe perpetual calendar that is more practical, more accurate, and easier to own. The Padellone is a museum piece, not a daily wearer.”

Viewpoint C (The Pragmatist): “The Padellone is a fascinating historical artifact, and it deserves its reputation. But it is also a niche product for a niche audience. It is for the collector who already has the Submariners and the Daytonas and wants something that no one else has. It is not for the beginner, and it is not for the investor who is looking for a safe bet. The market for vintage complicated Rolexes is thin and volatile. If you buy one, buy it because you love it, not because you expect it to appreciate.”

The New Padellone: A Modern Revival

In 2026, Rolex surprised the watch world by reviving the Padellone name for a new model in the Perpetual collection [citation:1][citation:4]. The new Perpetual Padellone is a 39mm watch with an annual calendar and moonphase, available in Everose gold or platinum [citation:1]. It features a new calibre, the 7190, with an instantaneous calendar mechanism and a Haplos system that distinguishes between 30- and 31-day months [citation:4]. The moonphase disc is blue enamel with meteorite moons, a playful reference to the original [citation:4].

The new Padellone is not a reissue. It is a reinterpretation, and it demonstrates that Rolex is willing to revisit its more classical, complicated past [citation:1]. Whether it will achieve the same cult status as the original remains to be seen. But its existence is a reminder that the Padellone ref. 8171 is not just a footnote in Rolex history. It is a reference that the brand itself now recognizes as significant.

The Verdict: A Unicorn Worth Understanding

After considering the history, the design, and the market for the Rolex Padellone ref. 8171, the conclusion is that this is one of the most fascinating watches Rolex has ever produced. It is rare, it is complicated, and it is beautiful. It represents a side of Rolex that the modern brand rarely shows: the side that was willing to compete with the great complications of mid-century watchmaking.

The Padellone is not for everyone. It is expensive, it is fragile, and it requires a level of care that most modern watches do not. But for the collector who understands what it represents, it is a grail. It is a watch that tells a story about a brand that was willing to try something different, and that story is worth preserving.

Whether you encounter one at auction, in a dealer’s case, or through a platform like Montres8.com, the Padellone is a watch that rewards knowledge. It is a reminder that the most interesting watches are not always the most famous ones. Sometimes, they are the ones that were too unusual to last.

One final thought: the Padellone’s nickname, “large frying pan,” is affectionate, but it also captures something essential about the watch. It is a tool that was repurposed for elegance. It is a complication that was never meant to be practical. It is a Rolex that does not look like a Rolex. And that is exactly why it matters.
