FHF 64

Description

The ladies' watch movement FHF 64 was released in the early sixties. On the one hand, it still uses the classical construction with direct driven minute wheel, on the other hand, it contains a directly driven center second hand. Because of this, the FHF 64 is rather thick, especially due to its small diameter. You can call this as a “double decker”, since the fourth- and minute wheel are stacked and hence the escapement wheel needs an extra long axle.

The remaining parts of the movement are, except the missing regulator arm for the screw balance, of good quality. It uses an Incabloc shock protection on the movement side, another, unknown shock protection system on the dial plate and then escapement wheel is beared in two cap jewels. The winding system is constructed as a yoke system, of course.
