ZRC, founded in 1904 by Edmond Zuccolo and Joseph Rochet in Geneva, Switzerland, is a historic watch brand renowned for its specialized engineering in diving instruments and technical bracelets. The brand gained significant horological recognition in 1917 for inventing the first extendable metal watch bracelet and later became a key supplier for the French Navy between 1964 and 1985. Collectors and enthusiasts often favor the brand for its specialized engineering, professional heritage, and patented technical innovations such as the Easy Clean System (ECS) and the Crown Protection System (CPS).
The brand’s catalog is defined by several key collections and models: – Grands Fonds 300: An iconic professional dive watch characterized by its distinctive crown positioned at 6 o’clock to prevent underwater snags and its monobloc case construction.
– Grands Fonds 300 Réédition: A modern iteration of the heritage model that incorporates contemporary patented innovations for maintenance and safety.
– 1964 Spirit: A model that continues the brand’s vintage-inspired professional diving aesthetic while utilizing modern materials and movements.
