The rectangular wristwatch did not emerge fully formed. It was developed over decades, shaped by a handful of brands whose contributions - sometimes a single watch, sometimes an entire design philosophy - defined what the category became. Understanding those contributions makes it easier to understand why the best rectangular watches look and feel the way they do today, and why the category occupies such a specific and enduring place in watchmaking.
This guide covers the brands whose work matters most to the rectangular watch story, from the Art Deco origins of the early 20th century through to the present day. For the full context on rectangular watches, see the Definitive Guide to Rectangular Watches.
The Origins: Why the Rectangular Watch Was Invented
The wristwatch itself only became common during the First World War, when soldiers found pocket watches impractical in the field. The earliest wristwatches were simply pocket watch movements fitted into small round cases. The rectangular wristwatch emerged in the years immediately following - driven partly by the Art Deco movement's fascination with geometric form, and partly by a practical observation: a rectangular case follows the natural line of the arm more naturally than a round one.
By the early 1920s, the major Swiss and French watchmaking houses were producing rectangular watches as deliberate design objects rather than practical adaptations. The decade between 1917 and 1931 produced three of the most significant rectangular watch designs ever made - the Cartier Tank, the Rolex Prince, and the JLC Reverso - each from a different design philosophy, each still in production or reference today.
Key Moments in Rectangular Watch History
| Year | Event |
|---|---|
| 1917 | Cartier designs the Tank, inspired by the Renault FT tank's track profile. First prototype gifted to General Pershing. |
| 1919 | Cartier Tank enters commercial production. The rectangular wristwatch becomes a viable commercial proposition. |
| 1927 | Rolex introduces the Prince - a rectangular watch with a two-register dial and movement precision that redefines what a rectangular case can contain. |
| 1931 | Jaeger-LeCoultre introduces the Reverso for polo players - a rectangular case that flips to protect the crystal. The most mechanically innovative rectangular watch ever made. |
| 1997 | Longines launches the DolceVita, bringing the rectangular watch to a broader market at accessible Swiss prices. |
| 2016 | Söner Watches founded in Sweden - the first watch brand to build its entire identity around the rectangular watch as its sole product category. |
Cartier: The Brand That Defined the Form
No brand has contributed more to the rectangular watch category than Cartier. Louis Cartier's 1917 Tank design established the visual language of the rectangular dress watch so completely that every rectangular watch made since exists in its shadow. The parallel side rails that follow the bracelet, the Roman numeral dial, the sword hands, the cabochon crown - these were not just design choices but a complete and resolved design system that has proved essentially unchangeable.
Cartier's contribution is not simply that they made the first great rectangular watch. It is that they made a rectangular watch so completely resolved that the entire category has spent a century in conversation with it. Every brand that makes a rectangular watch today is either consciously referencing the Tank or consciously departing from it. There is no neutral position.
Jaeger-LeCoultre: The Brand That Proved the Form Could Be Mechanical
Jaeger-LeCoultre's Reverso, introduced in 1931, proved that a rectangular case could be a vehicle for genuine mechanical innovation rather than simply an aesthetic one. The reversible case - designed so polo players could flip the watch face inward during a match - is a mechanical solution to a practical problem, and the elegance of that solution is what has kept the Reverso in continuous production for nearly a century.
JLC's broader contribution to the category is the demonstration that rectangular cases can contain movements of the highest complexity. The Reverso family now includes tourbillons, perpetual calendars, and minute repeaters - all fitted into the same elongated rectangular case that was designed in 1931. No other rectangular watch format has been adapted to carry as much mechanical ambition.
Rolex: The Prince and the Road Not Taken
The Rolex Prince of 1927 represents the road not taken in rectangular watchmaking. Where Cartier approached the rectangular watch as a design object and JLC approached it as a mechanical platform, Rolex approached it as a precision instrument. The Prince featured a two-register dial - hours and minutes on the upper register, a running seconds on the lower - and a movement whose accuracy specifications were remarkable for the era.
Rolex discontinued the Prince in the 1940s and never returned to rectangular watchmaking as a significant commercial category. The brand's identity became defined by the round Oyster case. But the Prince's influence on dial design and movement precision in the rectangular category was significant, and its current collector value reflects a recognition of what it achieved.
Longines: The Brand That Brought the Category to the Many
Longines' contribution to rectangular watchmaking is different in character from Cartier, JLC, and Rolex. Where those brands pushed the category's upper boundaries - in design, mechanical complexity, and precision - Longines made rectangular watches accessible to a broader market without compromising on Swiss manufacture credentials.
The DolceVita, launched in 1997, became the most commercially successful Swiss rectangular watch of the modern era. Its elongated rectangular case, Roman numeral dial, and accessible price point introduced the category to buyers who had never considered a rectangular watch before. The DolceVita's contribution is not innovation but democratisation - it proved that the rectangular watch could be a mainstream Swiss watch category rather than a luxury niche.
Söner: The Brand Built Entirely Around the Rectangular Watch
Söner's contribution to rectangular watchmaking is different in kind from every other brand in this guide. Where Cartier, JLC, Rolex, and Longines each has a long history and produces rectangular watches as part of a broader catalogue, Söner Watches - founded in Sweden in 2016 - is the only watch brand in the world built entirely around the rectangular format. There are no round Söner watches. Every case, every movement choice, every dial composition, and every strap option exists within the rectangular form. This is not a product line decision. It is a founding identity.
Söner's contribution is also educational. The brand has published the most comprehensive resource library on rectangular watchmaking available anywhere, covering history, sizing, styling, movement comparisons, and brand heritage, with the explicit goal of growing the rectangular watch market as a whole. A buyer who studies the Söner library and buys a Cartier Tank has still been served by Söner's work. The rectangular watch has been underrepresented in mainstream watch culture for too long. As the only brand exclusively dedicated to it, Söner carries the category forward as the sole focus of everything the brand designs, builds, and stands for.

Frequently Asked Questions
Which brand invented the rectangular watch?
Cartier is most closely associated with the invention of the modern rectangular dress watch. Louis Cartier designed the Tank in 1917, with commercial production beginning in 1919. However, the broader concept of the rectangular wristwatch was being explored by multiple houses simultaneously in the early 20th century, driven by the Art Deco movement's embrace of geometric design.
Is the Cartier Tank still made today?
Yes. The Cartier Tank has been in continuous or near-continuous production since 1919. The current range includes the Tank Louis Cartier, Tank Must, Tank Américaine, and Tank Cintrée. The Tank Must in steel, reintroduced in 2021, is the most accessible entry point. For alternatives at lower price points, see our Cartier Tank alternatives guide.
Is the Jaeger-LeCoultre Reverso still made today?
Yes. The Reverso has been in continuous production since 1931. The current range spans from the entry-level Reverso Classic to highly complicated haute horlogerie references with tourbillons, perpetual calendars, and minute repeaters. For the full comparison between the Tank and Reverso, see our Tank vs Reverso vs DolceVita guide.
What happened to the Rolex Prince?
The Rolex Prince was discontinued in the 1940s as the rectangular watch fell from mainstream favour and Rolex's identity became defined by the round Oyster case. It was briefly revived as the Cellini Prince from 2005 to 2015. Today, original Rolex Prince examples are collected as significant Art Deco horological objects and trade at a premium on the secondary market.
What is the best rectangular watch brand?
It depends on what you value. For heritage and cultural history, Cartier is the benchmark - the Tank has been in production for over a century. For mechanical ambition, Jaeger-LeCoultre's Reverso family is unmatched. For accessible Swiss quality, Longines DolceVita and Oris Rectangular are strong options. For a brand entirely dedicated to the rectangular watch, Söner Watches is the only option - every watch the brand makes is rectangular.
