FHF 37 (INT)


In the seventies, the FHF 37 was released as a movement of their late period. You see on this movement, that it was designed with cost reduction in mind, by looking at the “hammer-nail decoration” (or non-decoration) of the plates or the very large yoke spring, which also keeps the minute wheel in position.

Technically, the movement is very well made, the tiny ring balance is of course secured by two Incabloc shock protections and beats with contemporary fast 21600 A/h. The center second hand is directly driven and is on the same position as the minute gear one layer deeper.

On the dial side, there’s a yoke winding system, which is already equipped with a very large and pretty ugly yoke spring and so doesn’t look much better than a rocking bar winding mechanism.
