Kasper 100
Description
The cylinder movement Kasper 100 is from german pre-WWII production.
Unlike most other contemporary cylinder movements, this one already uses silver-toned plates and bridges.

The Kasper 100 uses 6 ruby bearings / cap jewels: Four for the balance and two for the bearing of the cylinder wheel.

Even though the specimen shown here runs pretty strong and steady after a revision, it shows a completely irregular pattern on the timegrapher. This is the result of the tips of the cylinder wheel permantly having contact with the balance cylinder. The noise of it completely fools the timegrapher.

On the dial side, you can see the rocking bar winding mechanism and the very simple click mechanism, which consists only of a simple spring.
