Description

The FHF caliber 72, which is obviously a direct relative of the FHF 67, is a very nice classically constructed mens' watch movement.

The center second of this flat movement is directly driven; the ring balance with screws uses a blue Nivarox-1 hairspring, which is still non-adjustable connected to the balance cock. The missing regulator arm gives it a slightly modern touch.

How rugged this movement is, can be seen on the specimen shown below: It survived an amateurisch skeletonize attempt by myself.
