FHF 1144

Description

The FHF 1144 is an early windup movement and has got a diameter of 9 3/4 lignes.

With 15 jewels and a pallet lever escapement, it belonged to the upper class movements of that time, probably in the 1920s.

We have the classical gear train here: The mainspring barrel drives the center minute wheel, followed by third wheel, seconds wheel (at 6 o’clock to carry the decentral seconds indication hand) and the filigree steel escape wheel.

The latter one is, pretty old-fashioned, beared under its own cock, while seconds-, third and minute wheel are beared under a moderly shaped bridge.

Because of this, the chronologically classification is pretty hard, the best guess are the 1920s.

The slotted, two-leg Guillaume screw balance is not yet shock protected. On the balance cock, the beating frequency can be adjusted with a fine regulator arm.

Because of its very characteristically shaped setting lever spring with its u-shaped cutout and the large balance wheel bearing plate, this movement could finally be identified as an FHF 1144.

Further characteristics are the vertical edge a 9 o’clock, which is known from pocket watch movements, and two flattenings at 6 and 12 o’clock, which were not photographable.
