Rare Rolex:
Inside the Rectangular Cellini Prince

By: Louise Henry Published: 21 April 2025 Last updated: 22 April 2025

When we think of Rolex, a certain image tends to form: round cases, robust proportions, and that unmistakable Oyster silhouette. It’s a design language that’s become almost synonymous with the brand. But every so often, Rolex veers off script. Quietly. Subtly. And when it does, the result can be unexpectedly compelling.

Take the Cellini Prince. This is a Rolex that feels somehow out of time—at once modern in execution and evocative of the brand’s early 20th-century roots. It isn’t a tool watch, and it’s not something you’ll see on wrists every day. But for those who appreciate Rolex’s less-traveled paths, it stands as one of the most distinctive and refined designs the brand has ever produced.

A Watch Born in the 1920s

The Rolex Prince made its debut in 1928, at a time when the wristwatch was still finding its form - both literally and figuratively. Shapes weren’t yet standardised, conventions were still evolving, and watchmakers had room to experiment. Even so, the Prince stood out.

Its rectangular case was only part of the story. What truly set it apart was its distinctive dual-dial layout: hours and minutes displayed above, with an enlarged seconds sub-dial taking pride of place below. This wasn’t just aesthetic - it was functional. The design earned the Prince the nickname “the doctor’s watch” thanks to that oversized seconds register, which made it easier for physicians to time a patient’s pulse with precision.

Yet the Prince wasn’t simply utilitarian. It was technically impressive, too. Many early examples were chronometer-certified and showcased a level of finishing that was rare for Rolex at the time. This was a watch built not just to tell time, but to elevate it.

Housed in slim, elongated cases - often crafted in gold or platinum—the Prince reflected the Art Deco elegance of its era. These weren’t rugged tool watches. They were refined instruments of timekeeping, designed with an eye toward symmetry, proportion, and style.

The Quiet Return - Cellini Prince

For decades, the Prince quietly disappeared from Rolex’s catalogue. That changed in 2005, when Rolex launched a modern reinterpretation under the Cellini line. Known officially as the Cellini Prince, this watch was something entirely different from the Rolexes most people had come to know in the post-Oyster era.

Here was a watch with a rectangular case, a manually wound movement, and a sapphire exhibition caseback - one of the very few times Rolex has ever made a movement visible. The finishing on the caliber 7040 was deliberately decorative, with Geneva striping, polished bevels, and a classic three-quarter plate architecture. It was a deliberate homage to the past, and to the kind of watchmaking Rolex once embraced more openly.

The Cellini Prince was released in a handful of variants, all crafted in 18k gold - white, yellow, and Rolex’s proprietary Everose. Each featured a distinctive guilloché dial, divided into two registers echoing the original’s signature format. Two references stand out in particular:

Ref. 5442: Encased in Everose gold with a chocolate and pink dial, this version plays with warmth and tone. The vertical guilloché pattern adds a sense of depth, while the color contrast between the subdials brings the Art Deco elements to the fore. On the wrist, the 5442/5 feels elegant without being delicate - a modern tribute that still feels rooted in heritage.

Ref. 5440: The white gold variant takes a cooler, more austere approach. Its silver-tone guilloché dial and blackened numerals give it a classic monochrome look, underscoring the architectural nature of the design. For collectors who appreciate minimalism and symmetry, this reference offers quiet sophistication.

Not Your Everyday Rolex

The Cellini Prince never became a mainstream success, and that was likely never the goal. At a time when Rolex’s sports watches were beginning to dominate both enthusiast and mainstream culture, the Prince was almost anachronistic. It had no Oyster case, no rotating bezel, and no steel bracelet. It wasn’t water resistant. It wasn’t a “tool watch.” Instead, it was a callback to an era when wristwatches were still primarily about elegance - and when Rolex was just one of many Swiss brands trying to find its identity.

For modern collectors, that’s precisely where the appeal lies. The Cellini Prince doesn’t compete with the Daytona or the Submariner - it stands apart entirely. It appeals to a different kind of Rolex enthusiast: one who’s drawn to the brand’s history as a whole, not just its most iconic chapters.

A Watch for the Collector’s Eye

There’s also rarity to consider. The Cellini Prince was only in production for a few years and never in large quantities. It wasn’t a commercial smash, which means examples on the market today are relatively scarce. That makes it one of the more overlooked modern Rolex models - and one that may well grow in appreciation as collectors continue to dig deeper into the brand’s lesser-known offerings.

While the Cellini line has often sat quietly alongside Rolex’s more celebrated sport models, the Prince serves as a reminder of what the brand is capable of when it focuses purely on design. It wasn’t made to chase trends or fill a gap in the catalogue - it was made to reflect a different side of Rolex’s heritage. And in doing so, it adds a thoughtful, often overlooked chapter to the broader Rolex story.

Final Thoughts

The Rolex Prince, both in its original 1920s form and its 21st-century Cellini revival, represents a fascinating detour in the brand’s design language. It’s a rare shape, a rare format, and in many ways, a rare philosophy—one centered on elegance, proportion, and horological purity.

In a landscape where Rolex is often defined by what everyone else wants, the Prince is defined by what few truly understand. And that makes it, in many ways, the most Rolex watch of them all.
