Description
The movement shown here is a pre WW-II cylinder movement by AS, most probably an AS 175, at least
as identified by the Flume K1 Werksucher. Since there are also two stamped digits on the
dial side, there's a small possibility, that this movement is one of its precessors, maybe an AS 67.
It has got a cylinder escapement and a classically constructed gear layout with distinct
bridges. Altogether, only seven jewels were used. Those kinds of movements are as
precise as a chronometer, they might gain or lose several minutes a day and from time to time even stop. The
specimen displayed here does exactly that, too.
An interesting fact is, that one the dial-side there's a rocking bar winding mechanism, which
winds the mainspring there, but on the movement side, there's the click spring for it. And what
the crown wheel of the winding system is for, is unknown, since it has no use at all.
