The Châtelain family became involved with watch production in 1936, focusing on clasp and case polishing. The company was restarted after World War II, launching as G&F Châtelain SA in 1947 and growing to include jewelry and high-end watch case production. In 1963, Francis Châtelain invests in metal stamping company Sandoz & Co., which is absorbed into G&F Châtelain in 1993. By the 1990s, G&F Châtelain was actively involved in many aspects of watch and jewelry finishing.
Chanel purchased G&F Châtelain in 1993, leveraging the company for production of their watches. G&F Châtelain and Chanel began producing ceramic watch cases and components in 2006, and this is now a specialty of the company. Today, G&F Châtelain produces and finishes watches for Chanel and Bell & Ross.
