AS with cylinder escapement

Description

This old cylinder escapement movement from AS was made far before WW II. It measures 5 3/4 x 8 1/2 lignes and resembles a bit the AS 846.

It contains a cylinder escapement and a rocking bar winding system on the dial side, which is very unusual constructed: The click spring resides on the movement side and the winding system even turns a completely functionless(!) crown wheel.

This movement was used in this ladies’ watch, marked as “Restos” or “Bestos”, probably from Switzerland:
