Description

The Felsa 4025 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, especially with you take into account, that it containts a date indication to boot.

The speciality of this movement is, that it doesn't have a second hand. A movement with date indication but no second hand is really something rare.

Nevertheless, the rest of this movement 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.

The date advances slowly and can be corrected semi-fast. It is noteworthy, that on this movement, the date is displayed at position "6", which agrees with the symmetry of the dial.
