Corum
a new chapter
The great story of CORUM began in 1955 with René Bannwart and his uncle Gaston Ries. Fascinated by the word “quorum,” which refers to the minimum number of people required to be present to make decisions, René Bannwart simplified its spelling — and CORUM was born.
From its earliest days in La Chaux-de-Fonds, CORUM set out to position itself at the forefront of Swiss watchmaking. Its emblem — a key pointing skyward — symbolizes the ambition to unlock new territory, pursue innovation, and act with purpose. It also reflects the inventiveness, tenacity, and audacity required to master time. By 1956, it was already recognized by its peers as one of the most creative brands in the industry.
In 1966, the founder’s son, Jean-René Bannwart, joined his father at the company. From this partnership emerged the models that would become CORUM’s signature.
In the 1970s, whether with bird feathers or a Rolls-Royce, nothing could curb CORUM’s creativity. Its exceptional expertise allowed the brand to unite technical prowess with artistic expression.
From this avant-garde vision emerged the iconic models that would come to define CORUM, embodying the very pinnacle of watchmaking mastery. After forging the very first partnership with a prestigious automobile manufacturer, CORUM also became the first to use meteorite — sourced directly from Greenland — to craft a watch dial.
Technical audacity defined the 1980s. CORUM pushed the boundaries of watchmaking, asserting a bold visual signature that was instantly recognizable. In the decades that followed, the brand multiplied world firsts. Tides, marquetry dials, XXL magnifying crystals — CORUM established itself as a true laboratory of ideas in the service of Haute Horlogerie. From flying tourbillons to luminescent carbon and Métiers d’Art, pioneering heritage and contemporary creativity became inseparable.
April 30, 2025 — For its 70th anniversary, CORUM has chosen not to look back in nostalgia. Instead, the great Swiss watchmaking house opens a new chapter — one as bold as its beginnings.
The iconic manufacture of La Chaux-de-Fonds returns to its roots. A buyout led by its Sales Director, Haso Mehmedovic, alongside a group of seasoned Swiss investors, brings CORUM back into Swiss hands.
From the workshop floor to commercial leadership, from production to quality, Haso Mehmedovic has experienced every cog of the company. At just 32, the man who knows its soul better than anyone becomes CEO and Chairman of the Board of CORUM 1955.
CORUM
The Inside Man
Uncommon. The story of Haso Mehmedovic and that of CORUM share a taste for the exceptional, for the unconventional — as if they were meant to meet.
He obtained all his practical watchmaking diplomas at the Le Locle watchmaking school, which at the time certified only 30 students out of nearly 300 applicants. With his federal diploma in hand, Haso sent out only one résumé — to CORUM. He was hired immediately.
On May 5, 2025 (5.5.25), he is finalizing a Management Buy-Out (MBO) — the acquisition of CORUM by its own management team.
Since that day, Haso Mehmedovic has served as Chairman and CEO of CORUM.

Boldness is never proclaimed — it is proven. Since 1955, each timepiece unveiled has explored its own array of novel forms, complications, and materials. Without exception for seventy years. This is what makes CORUM singular: design and movement are inseparable.
If CORUM dares to push every boundary, it is also because it is, at heart, a family story. From its founding—born of the shared vision of a man and his nephew—to its collaborators today, family values have always been present and remain embedded in its DNA.
This heritage, balancing tradition and creative exploration, is perfectly embodied in a spatial philosophy that speaks for itself: the designer and the technical office do not work opposite one another, but side by side.
At CORUM, no boundary exists between aesthetics and engineering. A movement is conceived like a sculpture; a dial is developed like a caliber. This uncompromising pursuit of coherence between form and mechanics is perhaps what most profoundly sets the Maison apart from its peers.
Two collections capture the essence of CORUM like no others: Admiral and Golden Bridge. Two pillars, two contrasting characters, united by the same exacting standards. It is upon these foundations that the Maison now reasserts its place at the forefront of fine watchmaking.
Sapphire holds a special place within the world of CORUM. A material of choice, it reveals, enhances, and elevates. It is the natural accomplice of a Maison that has never sought to conceal its mechanisms — quite the opposite.
A strap is never a mere detail. It is the element that physically connects the watch to its wearer — an almost visceral bond that demands as much rigor as the movement itself. At CORUM, it is conceived, designed, and crafted with the same exacting standards as the timepiece it completes.
Every detail matters. Every decision — the angle of a chamfer, the finish of a link, the curve of a caseback — is the result of countless discussions and constant refinement. Excellence is a habit.
Nonconformist by nature, CORUM has never followed trends. Its compass is its own vision — irreverent, creative, and resolutely singular. A CORUM timepiece is always distinguished by that intangible soul which defines its unique character.

La chaux-de-fonds
La Chaux-de-Fonds is a Swiss town located in the Jura mountains a few kilometers from the French border. Founded in 1656, it owes its growth and renown to watchmaking. The architect, Le Corbusier, writer Blaise Cendrars and automobile maker Louis Chevrolet were born here.
It is a renowned centre of Art Nouveau and since 2009 has been classified a UNESCO World Heritage site for its typical urban landscape of the watchmaking industry. Today, it remains a very significant watchmaking center and is home to some of the most famous watchmaking manufacturers. In 1955, the year it was founded, the House of CORUM was established at La Chaux-de-Fonds.
