Comments about the data
unusual: crown mechanism with rocker bar, but in some variants ratchet wheel on the back side
There are variants with click on the dial side, ratchet wheel on the back side with or without functionless crown wheel.
The assignment of these variants to the numbers 1237, 1238, 1245, 1249, 1269 is widely unknown; only the AS 1245 is known to have a ratchet wheel on the back side.
Example, year: signature; shock device
ca. 1950: AS 1237/38, Swiss Made, 17 Jewels
