FHF 59N

Description

The FHF 59N is one of the smallest form movements ever made, and besides this the absolutely smallest baguette-type movement with only one layer (compare Omega 690, which uses two stacked layers of gears).

The crown wheel is also noteable: The theeth are slanted on the outher side to make the opening on the movement as small as possible to safe another few tenth of a millimeter in height.

The gear construction is a classic one with the non shock protected screw balance, whose hairspring is fix connected to the balance cock and can be adjusted by a long regulator arm. The pallet lever movement is made in one single layer and directly drives the center minute hand. The escapement wheel is beared with two cap jewels, thus avoding interferences with the overlapping fourth wheel.

On the dial side, the service friendly construction is continued: The large holes in the main plate allow easy servicing and oling of the pallet stones.

The FHF 59N uses a yoke winding system just like many other good movements do.
