AS 1780

AS 1780


A rather late, but a little bit unusual constructed movement is this 8 3/4 ligne ladies' movement of AS. You can clearly see the rationalization influences of the sixties. Technically it resembles very well the state-of-the-art of that time: The large nickel ring balance beats with 21600A/h and in beared in Incabloc shock protection systems. The hairspring stud is moveable, the hairspring regulator has got no arm.

This movement uses an eccentrically located minute wheel (on the movement side at "5", on the dial side at "7"), which drives the hands indirectly. This kind of construction allows larger balances and mainsprings on smaller movements, which influence the daily rates and run time in a positive way.
