Notes
These 2 prototypes are truly important as they represent the first quartz movements ever developed by the Centre Electronique Horloger (CEH) and were submitted to the Concours d'Observatoire in Neuchatel in 1966 and 1967. Only ten examples were made and when submitted for the competition, the 10 first prices all came from the new calibers and amazingly these new calibers improved the precision 10 times compared to mechanical wristwatches marking a new debut in the era of quartz.
