Henry Louis Belmont was a pivotal figure in 20th-century French horology, best known as the founder of the watchmaking brand Yema. Born with a deep interest in mechanics, Belmont pursued formal training at the National Watchmaking School of Besancon, the historic center of the French watch industry, where he graduated at the top of his class in 1931.
Following his education, Belmont gained significant professional experience at Lip, which was then the premier French watch manufacture. During his tenure there, he rose to the position of technical manager, honing his expertise in production organization and technical design. His work at Lip provided the foundation for his later entrepreneurial success, as he observed the transition from traditional artisanal methods to industrial-scale manufacturing.
In 1948, Belmont realized his vision of independence by establishing his own company, Yema, in Besancon. He began the venture with a small team of watchmakers and quickly implemented advanced production and marketing strategies. Under his leadership, the brand became a pioneer in the design of high-performance “tool watches.” Notable milestones during his tenure included the 1953 launch of a dive watch capable of reaching depths of 100 meters and the 1963 introduction of the iconic Superman, a professional-grade diver’s watch featuring a patented bezel-locking mechanism.
Belmont was also a visionary in the field of industrial automation. He founded Sormel (Societe de Recherche de Mecanique et d’Electronique), a company dedicated to robotics and automated assembly lines for watchmaking. He believed that the future of the industry lay in modernization and standardization, which allowed Yema to become the leading French watch exporter by the late 1960s, producing hundreds of thousands of units annually for global markets.
Beyond his commercial success, Belmont was highly respected for his technical contributions to horology, particularly his research on the cylinder escapement. In 1978, he was awarded the Legion d’Honneur for his significant impact on the French watchmaking industry. After resigning from active industrial management in 1982, he dedicated his later years to horological history and research, collaborating with the International Museum of Horology until his death in 2002. His legacy remains central to the identity of Yema, which continues to operate as a prominent French watchmaker today.
