The ETA 2465 watch movement is a mechanical movement that is equivalent to the Record 1955 and Longines 501 movements, with the only known difference being the rotor design. The movement line was originally designed by Record and later adopted by Longines after their acquisition of Record. It is unclear if there were other variants of this movement available as Wittnauer calibres. The Wittnauer versions of this movement include manual-wind versions and an automatic version without a date function, which have not been seen from Record or Longines. The specific differences between the C11KAS and C11KAS1 variants are unknown. This movement features automatic winding, a sweep second hand, and a date function that is set by changing the time to 19:30-24h. The C11KAS1 movement was used during the period around 1968.
