About Kyburz & Cie SA
Kyburz & Cie SA is a Swiss company founded in 1946, headquartered in Marin-Epagnier in the canton of Neuchâtel, and is regarded as a pioneer in the development and manufacture of transparent products. The company produces watch glasses made of mineral glass, sapphire and plastic as well as dial components such as retaining rings, inlays and dials made of transparent or coloured technical resins. Its manufacturing capabilities include resin injection through thermocompression moulding with standard, recycled or bio-based resin, machining of resin parts, coating, and the in-house NexScratchGuard scratch-protection treatment, which makes resin and Hesalite parts resistant to scratches, impacts and solvents. In addition, Kyburz offers toolmaking for its own production and for customers. Customers come from the watch industry, medical technology, optics and metrology; references include Zenith, TAG Heuer, Junghans, Tesa Technology and Mitutoyo. As an active company in the Agence de l'énergie programme, Kyburz carries the CO2 & kWh réduits label and manufactures products from recycled resin for individual customers.
