What is "cortebert"

Cortébert is a municipality in the Jura bernois administrative district in the canton of Bern in Switzerland. It is located in the French-speaking part of the canton in the Jura mountains.

Cortébert Production under the Cortébert brand name stopped in the mid-1970s. Cortébert used to be one of the highest regarded premium watch brands, manufacturing their own movements, supplying movements to other brands such as Rolex and introducing a jump-hour movement later adopted by IWC. When the quartz crisis hit the industry in the '70s, the majority of prestige brands ceased production including Cortébert.
