FHF 152
Description
The FHF 152 is a movement of the caliber series FHF 150, which was made between 1938 and 1952 in quantities of over 1.4 million items. For the time being, its execution was already pretty modern with clearly cut bridges, which were available in different shapes.
The base plate of this 10 1/2 ligne movement shows its good quality, all important bearings contain rubies:
base plate (FHF 150)
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.
gear train (FHF 150)
The not shock protected screw balance regulates 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”.
