Cortébert was a Swiss premium watch brand, 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 1970s, the majority of prestige brands ceased production, including Cortébert.
History
Abraham-Louis Juillard opened his small watchmaking store in Cortébert village in Switzerland in 1790. This date is commonly used as the date of founding although the Cortébert brand name was not registered until 1855 using the bottony cross as a logo.
Cortébert became well known for their railroad watches: they supplied both the Turkish railroad system and the Italian railroad system, as well as a number of street car systems throughout Europe.
In the 1927, at the request of Mussolini, Cortébert started distributing their watches in Italy under the Perseo brand name, as fascist Italy rejected foreign brand names. It is under this name that they were used by the Italian railway system.
The Russian watch factory Molnija produced a number of calibers that were very similar to Cortébert's 16 Ligne Cal. 620.
By 1944 Cortébert had a lineup consisting of 20 different calibers.
