Certina Glasses
Certina S.A. was founded in 1888 when Adolf and Alfred Kurth opened in Grenchen their first movement and supplies factory for the watchmaking industry. At the start Certina's staff consisted of three employees working in a workshop that was connected to the family home. They did not begin producing complete watches and timepieces for a few years which they then did alongside their work producing movements for other companies. By 1938 the company had expanded and 250 employees celebrated the 50th anniversary of the company. 1983 Certina became a member of the Swatch Group.
