Corum is a Swiss luxury watch manufacturer that has established a distinct identity within the horological world since its inception in the mid-20th century. Headquartered in La Chaux-de-Fonds, a city renowned for its deep-rooted watchmaking history, the brand is recognized for moving beyond traditional aesthetic norms. Its philosophy centers on a “key to beautiful time,” symbolized by an upright key logo that represents the unlocking of new mysteries and innovations in timekeeping.
The brand was founded in 1955 by René Bannwart and his uncle, Gaston Ries. Bannwart was a seasoned veteran of the industry, having previously acquired significant experience at prestigious houses such as Patek Philippe and Omega. Ries had already been operating a watchmaking workshop in La Chaux-de-Fonds for several decades before joining forces with his nephew. The name Corum was derived from the Latin word “quorum,” simplified for easier pronunciation while retaining the meaning of the minimum number of people necessary to make a valid decision.
One of the primary reasons enthusiasts are drawn to Corum is its commitment to unconventional design and “world premier” concepts. Rather than producing standard iterations of classic tool watches, the brand often treats timepieces as collectible artistic objects. Collectors appreciate the brand’s willingness to experiment with unique materials—such as bird feathers, meteorites, and authentic currency—and its ability to stage mechanical movements in architecturally transparent cases.
The Admiral collection, formerly known as the Admiral’s Cup, stands as one of Corum’s most enduring and recognizable lines. Launched in 1960 to honor the legendary sailing regatta, the collection is defined by its signature twelve-sided (dodecagonal) case and the use of colorful nautical pennants as hour markers. These flags correspond to the international maritime code of signals, firmly anchoring the watch’s identity in the world of competitive sailing and luxury yachting.
Another cornerstone of the brand’s prestige is the Golden Bridge collection, introduced in 1980. This piece is celebrated for its revolutionary linear baguette movement, which appears to float in mid-air inside a transparent sapphire crystal case. The movement was originally designed by independent watchmaker Vincent Calabrese, and Corum was the first to realize the concept’s potential. The Golden Bridge is often cited by purists as a masterpiece of micromechanics that elevates the movement itself to the status of a primary visual art form.
The Coin Watch represents Corum’s fusion of historical heritage and high horology. First introduced in 1964, the watch features an ultra-thin movement meticulously fitted inside an authentic gold coin, such as the $20 Double Eagle. This model gained significant cultural status as the “President’s Watch,” having been worn by multiple U.S. leaders, including Lyndon B. Johnson, Richard Nixon, and Ronald Reagan. It remains a key piece for those who value the intersection of numismatics and watchmaking.
For those seeking avant-garde aesthetics, the Bubble collection offers a bold departure from conventional proportions. Created in 2000 under the leadership of then-owner Severin Wunderman, the watch is characterized by an exceptionally thick, domed sapphire crystal that creates a magnifying effect on the dial. The Bubble has served as a canvas for numerous limited editions featuring pop-culture motifs and provocative imagery, making it a favorite among collectors who prefer a more playful and disruptive luxury style.
The Romvlvs collection, debuted in 1966, showcases Corum’s history of functional innovation. It was the first watch to feature hour numerals engraved directly onto the bezel rather than the dial, a design choice born from a production delay that turned into a permanent aesthetic signature. This collection emphasizes the brand’s “Art Deco” roots and its ability to turn technical challenges into distinctive design elements that have remained relevant for decades.
In recent years, Corum has seen a significant strategic shift in its ownership and leadership. After being owned by the Hong Kong-based Citychamp Watch & Jewellery Group for over a decade, the brand returned to Swiss hands in early 2025 through a management buyout. The company is now led by CEO Haso Mehmedovic, a trained watchmaker who has spent his entire career at Corum. This transition marks a return to its roots as a Swiss-owned manufacture with a renewed focus on high-end craftsmanship and diminished industrial reliance.
Today, Corum continues to balance its rich heritage with a pioneering spirit, maintaining its position as a “laboratory of ideas” in Haute Horlogerie. By focusing on its three cardinal pillars—the Admiral, the Golden Bridge, and the Bubble—the brand offers a diverse portfolio that appeals to niche collectors and luxury enthusiasts alike. Its commitment to technical innovation and bold, recognizable silhouettes ensures that Corum remains a singular voice in the global landscape of fine watchmaking.
