The FHF caliber 28 is an interesting mens’ size movement from the mid last century.
Since this movement uses a direct driven center second, but was constructed in a classic way with a large minute wheel, it had to be made in two layers, which led to a large height. Be the slanted shape of the bridge gives it a very pleasent look and the two gold-toned chatons made it technical superior, too. So, it’s easy to say, that FHF belonged to the upper league.
The balance is, a bit unusal for FHF, beared in two three-leg shock protection systems, like Trishock.
On the dial side, you can see, as usual on better movements, a yoke winding system, a cap jewel for the anchor wheel and a preparation for alternative shock protections.
