About Jean-Pierre Clément & Cie S.A.
Jean-Pierre Clément & Cie S.A. is a Swiss precision mechanics company based in Tramelan in the Bernese Jura, specialised since 1959 in décolletage (sliding-head turning), mechanical and electronic precision turning as well as milling work. The company manufactures highly precise components for the watch and jewellery industry as well as other demanding industries, also machining precious metals and special materials such as copper alloys, gold, titanium and stainless steel. In addition to machining, the company offers trovalisation and diamond finishing as mechanical surface finishing processes up to mirror-gloss polishing. Machine set-up is carried out with micrometric tolerances, and every component batch is inspected using modern measuring systems and real-time monitoring. The company works for renowned watch and jewellery houses and places great value on Swiss quality standards, responsiveness and confidentiality.
