Description
The Felsa 22 with a diameter of only 6 lignes (13.55mm) belongs to the tinyiest movements ever
made in large quantities. And unlike other compareable small movements like the
ETA 2442 it is constructed in the old-fashion way with a directly driven
minute hand and hence only a very small screw balance.
The nice design with angled plates, you can estimate its high quality
 |
| older version without shock protection |
|
This movement was available with and without Incabloc shock protection system. It was was
available in versions with and without long regulator arm.
 |
| (almost) empty main plate |
|
The size of this movement was so small, that the minute wheel reached below the balance
cock and so could only be removed after the balance cock was put away.
Escapement wheel and the bearing of the fourth wheel also overlapped, but this construction was
very popular on small ladies' form movements. On round movements, this is pretty rare.
The golden toned Glucydur screw balance is so small, that it beats with faster 21600 A/h. This
combination is a very rare one!

On the dial side, you see besides the yoke winding system a very interesting type of the
Incabloc shock protection. It reminds of a cap jewel holder, and its bearings are very flat.
