The General 878 mechanical watch movement, introduced in approximately 1965, incorporates a pin-lever escapement and features a ratchet on the dial side. It employs a crown mechanism with a rocker bar and is later found under the designation Valjoux 7750, omitting the hour counter and day functions. The movement also includes functions such as manual winding, sweep seconds, Bascule Winding, KIF Shock Protection, and utilizes a pin lever mechanism.
