The Felsa 4022 belongs to the class of very small round ladies’ movements. With a diameter of only 7 3⁄4 lignes it is almost of the the smallest available size. Colored in copper it looks very nice and gives a nice contrast to the otherweise silver toned movements.
The movement itself is more or less standard. With its nicely shaped briges and the Incabloc-secured screw balance it is visually very appealing. It also contains a deck jewel for the anchor wheel and Felsa-unusual red anchor pallets, which are standard elsewhere.
This movement was also available with a date indication, as Felsa 4025.
