Edmond Zuccolo was a Swiss technician and inventor who played a foundational role in the history of the horological industry as the co-founder of the Zuccolo Rochet Company, known today as ZRC. In 1904, Zuccolo partnered with Joseph Rochet in Geneva, Switzerland, to establish a specialized workshop. While Zuccolo served as the workshop manager, his collaboration with Rochet combined technical innovation with industrial vision, initially focusing on the production of high-quality components for the watchmaking trade.
During the early 20th century, Zuccolo and his partner became renowned for their expertise in manufacturing pocket watch chains and “claw” bracelets, which allowed traditional gusset watches to be adapted for wrist wear. Their commitment to technical advancement was recognized in 1917 when the firm won the Prix de l’Industrie Nouvelle de Genève (Geneva Prize for New Industry). This accolade was awarded for their development of the first-ever extendable metal bracelet, a breakthrough that established the company as a world leader in the production of watch attachments.
Under the foundational principles set by Zuccolo and Rochet, the company remained a family-owned enterprise, passing through generations of the Rochet and Brunet families. This continuity allowed the brand to eventually transition from being a specialist in watchstraps and bracelets to a manufacturer of specialized timepieces. The technical DNA established during Zuccolo’s tenure later informed the development of the iconic ZRC Grands Fonds 300, a diving watch famously adopted by the French Navy (Marine Nationale) in the 1960s.
Edmond Zuccolo’s legacy is defined by his contribution to the industrialization of Swiss watch accessories and the establishment of a brand that has survived for over a century. Today, his name remains synonymous with the “Z” in ZRC, representing a history of Swiss craftsmanship and functional innovation that continues to influence the brand’s contemporary collections of professional diving instruments.
