Description

The FHF 150 is a movement, which was presumably made in the late 1930s or 1940s. For the time being, its execution was already pretty modern with clearly cut bridges, which were available in different shapes.

With 15 jewels, it used the highest normally used number of jewels of that time, but there were also extra high quality versions available with 17 jewels.

The base plate of this 10 1/2 ligne movement shows its good quality, all important bearings contain rubies:

This movement uses the classical gear train with mainspring barrel, directly driven center minute wheel, third wheel, seconds wheel at 6 o’clock (which can carry the decentral seconds hand on the dial) and finally the escape wheel.

In the specimen shown here, escape wheel and lever are golden toned!

The screw balance is in some version shock protected (with in Incabloc shock protection) and regulares a swiss pallet lever movement. The hairspring is fix connected with the very flat balance wheel cock, and can be adjusted in its effective length with an old-fashioned designes regulator arm.

The identification happens on the dial side only, but with the caliber number, you still don’t know the shape of the bridges, because in all cases, the movement is marked as “FHF 150”.

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.
