Description
The AHS caliber 40 is a simple, 10 1/2 ligne pin lever movement, made
in Germany in the 1950ies. It was available in different versions, among
them the one displayed here with a pointed staff and double plate.
There's no shock protection and also no jewels in the movement; the gears
run in brass bearings, probably a preparation for other
calibers, which were partially equipped with rubies.
On the dial side, there's of course only a simple rocking bar winding
mechanism and only a spring for the winding mechanism. This spring
had to be replaced on the movement displayed here. Fortunately, it
was compatible with other movements
of AHS.
The movement displays hour and minute, and there's also a sub-second
indication at position "6".
