Carl F. Bucherer's mechanical movements are made by the company’s own Manufacture and Swiss specialists. They feature practical additional functions specially developed for Carl F. Bucherer timepieces. After all components have been assembled with precision, and experienced watchmakers have regulated gear behavior, the watches are put through several days of testing of functionality, precision and power reserve. The caliber gear precision for several individual models is tested by the official Swiss chronometer inspection authority (COSC) and certified according to stringent criteria.
