Notes
equivalent to Record 1955 respectively Longines 501, except the rotor design
This movement line is a Record design, and it was adopted by Longines, when Record was acquired by Longines. It is not known, whether other variants were also available as Wittnauer calibres.
Manual-wind versions and the automatic without date I've only seen from Wittnauer, from Record or Longines not yet.
