Rolex is the world's most recognized watch brand, a name synonymous with precision, aspiration, and the round Oyster case that has defined its public identity for a century. The Submariner, the Datejust, the GMT-Master, the Daytona: these are the watches that built the legend, and they are all round. But before Rolex was the brand of the Submariner, before it was the watch of record that has graced the wrists of every astronaut and president and mountaineer who matters to the story of 20th-century achievement, Rolex made rectangular watches. And it made some of the best ones in the world.

The Prince - The Watch That Made Rolex Serious
The Rolex Prince came to market in 1928 and was, by immediate consensus, a masterpiece. Rectangular, Art Deco in its every proportion, it featured one of the most distinctive dial layouts in the history of wristwatch design: a dual-register format in which the time display, hour and minute hands, occupied the upper portion of the dial, while a small seconds sub-dial occupied a separate, clearly delineated lower portion. The two displays never overlapped, which is why the Prince acquired its informal nickname: "the doctor's watch," because its layout allowed for the precise timing of pulse beats and respiration without any hand interfering with any other. It was precision as design, and design as precision.
The Prince's case was powered by rectangular movements manufactured by Aegler, the Swiss company that had long supplied Rolex calibres, and it offered, for its era, an impressive power reserve of more than two days. Its case shapes varied across references: some were straight-sided and architectural, others used the dramatic "curvex" profile in which the lugs swept sharply downward to follow the wrist. Al Capone wore a Rolex Prince. Liam Neeson's Oskar Schindler wore one in Schindler's List. These are not trivial associations: they speak to the Prince as a watch for people who understood that elegance could be a form of power. Rolex discontinued the Prince in the early 1950s as the rectangular form fell from mainstream favour, but it never entirely forgot it.
The Cellini Prince - A Modern Resurrection
In 2005, at Baselworld, Rolex did something that astonished the watch world: it introduced the Cellini Prince, a rectangular Art Deco watch that revived the Prince's dual-register dial layout in a case measuring 28.5mm x 47mm, crafted in 18k gold in four configurations. The Cellini Prince was, and remains, unlike anything else Rolex has ever made. Its exhibition caseback, revealing the specially decorated rectangular movement, was a Rolex first. Its guilloché dial patterns, matched by corresponding decorations on the movement visible through the caseback, were evidence of a finishing capability that Rolex's round watches never display. The Calibre 7040, COSC-certified, was developed specifically for the Prince format. The watch was available in yellow gold, white gold, and Everose gold, each with its own distinct dial treatment, from the sunrise-pattern sunburst with Arabic numerals, to models with Clous de Paris hobnail textures, to white gold versions pavéd with diamonds.
The Cellini Prince sold poorly by Rolex's commercial standards and was discontinued in 2015. But for collectors who understand it, the Prince is among the most technically distinctive watches Rolex ever produced, a piece that reveals capacities in the brand that its mainstream catalogue never has occasion to demonstrate. On the secondary market, examples sell for considerably less than comparable round Rolex models of the same era, making the Prince, paradoxically, one of the best-value propositions in the entire Rolex catalogue.
The Secret Rectangle
Rolex's rectangular chapter is not a footnote, it is a window into a version of the brand that never fully emerged, a Rolex that might have been as important in the world of angular watchmaking as it became in round. The Prince of 1928 and the Cellini Prince of 2005 bookend nearly a century of intermittent engagement with the angular form, and what they demonstrate, together, is that when Rolex commits to the rectangle, it commits completely. The result is always worth finding.

Frequently Asked Questions
Did Rolex ever make rectangular watches?
Yes. Rolex produced rectangular watches across two distinct periods. The original Rolex Prince ran from 1928 to the early 1950s and is considered one of the finest rectangular watches of the Art Deco era. The Cellini Prince was produced from 2005 to 2015 as a modern revival of the Prince format in 18k gold with a COSC-certified movement. Both are significantly undervalued relative to Rolex's round models on the secondary market.
What is the Rolex Prince watch?
The Rolex Prince is a rectangular Art Deco wristwatch introduced in 1928. It is distinguished by its dual-register dial layout, in which the hours and minutes are displayed in the upper portion and a small seconds sub-dial occupies a separate lower section. This layout earned it the nickname "the doctor's watch" because it allowed precise timing without hand overlap. It was powered by rectangular Aegler calibres and offered a power reserve of more than two days for its era.
Why was the Rolex Cellini Prince discontinued?
The Cellini Prince was discontinued in 2015 after ten years of production. Commercial performance was below Rolex's expectations - the watch attracted a specialist collector audience rather than broad consumer appeal. Its complexity, the dual-register dial, the decorated rectangular movement, the exhibition caseback, sat outside the utilitarian design language that defines Rolex's mainstream identity. For collectors, this makes surviving examples particularly interesting.
Is the Rolex Cellini Prince a good investment?
The Cellini Prince represents one of the most technically accomplished watches Rolex ever produced and currently trades on the secondary market at a significant discount to comparable round Rolex models of the same era. For collectors who value technical distinction and finishing quality over brand recognition, it is an unusually strong value proposition. As with any pre-owned watch purchase, condition, provenance, and original documentation significantly affect value.
Where does Rolex sit in the rectangular watch category?
Rolex's rectangular output is a minor chapter in a catalogue dominated by round watches. In the broader rectangular watch landscape, the Prince sits alongside the Cartier Tank and Jaeger-LeCoultre Reverso as one of the defining Art Deco rectangular watches. Unlike those references, it is no longer in production. For the full context of how the rectangular watch category developed across the major houses, see the complete history of rectangular watches.
