The movement depicted in this page is AS153. Identified in a AS technical book from 1928.
The dial side of this movement is much more similar to that of the AS 137 than that of the AS 153 (both are in the Ebauches SA catalog from 1928).
But it’s strange anyway. In the catalog from 1928 the AS 137 is a Lépine (open face) movement. In the Classification from 1936 the dial side is a Lépine as well, but the bridge side is a Savonnette (hunter). Maybe AS used 137 for both versions. For the time being, I’ll keep the 137 designation for the movement shown here.
