FHF 150

Description

The FHF 150 is a rather old, 10 12 ligne pallet lever movement, which was probably already made in the late 1920ies (it was used in a watch, where a dedication of 1927 was engraved). It was modern made for that time with clearly cut brides and no decoration at all.

The non shock protected screw balance controls a pallet lever movement with a tiny second dial at “6”. The hairspring is fix connected to the balance cock, but is regulated in its effective length by an old-fashioned regulator arm.

With 15 jewels, it used the highest normally used number of jewels of that time.

On the dial side, you see the upper quality of the movement. To help with its adjustment, parts of a minute dial were engraved. Of course, a yoke winding system was used. It looks already very modern, so that I doubt its production year of 1927.
