The diameter of the FHF 32, which was launched in the early 1950s, is only 17.2mm (7 3/4 lignes).
As expected from FHFH, it is a quality movement, and the version shown here, with a golden toned Glucydur screw balance and three cap jewels on the gear bridge, is hard to top.
Of course, all important bearings contain rubies, only minute wheel and mainspring barrel have to metal bearings, but that’s absolutely sufficient, since the force of the gears is always high enough.
The gear train is contemporarily modern: The mainspring barrel directly drives the center minute wheel, followed by third wheel, seconds wheel and steel escape wheel.
The golden colored Glucydur screw balance is already beared in two Incabloc shock protections. It beats contemporarily slow with 18000 A/h. Its precise frequency can be adjusted with a long regulator arm and a scale.
On the dial side, you see the flat Incabloc bearing for the balance wheel, and on the opposite side the yoke winding system.
At 12 o’clock there’s a partial minute scale, which allowed the adjustment of the movement without dial.
