The AVI's and Co-Pilot's are rarer than the equivalent Navitimers and these models were originally more expensive than Navitimers of the same period. In the mid-sixties the name was changed from AVI to Co-Pilot, but both are still commonly used together.
The Venus 178 caliber in this model was also used by some of its predecessors like the Navitimer, Top Time and the earlier Co-Pilot or AVI models.
The Venus factory was established in 1924, but filed its first chronograph patent 1933. By then it was part of Ebauche SA holding company with rival brands Valjoux, Lemania and Landeron as the four designated chronograph manufacturers in the Swiss watchmaking cartel. Venus made chronographs for scores of now forgotten brands, but its biggest customer was Breitling. Most of the Premier and Navitimer models from the 1940s to the 1960s were fitted with caliber 175 and 178 movements. Heuer and Patek Philippe favored the Valjoux movements and Lémania was Omega’s supplier.
The best-known Venus chronographs include the caliber 175, introduced in 1940, and its derivative, the 178 with hours counter. By the sixties, the chronograph boom had definitely had its day, and Venus closed its doors in 1966. Its assets were absorbed by
Valjoux, which discontinued column-wheel production and concentrated on the Venus cam movement instead. Chronograph development was then dormant for decades following.
