AHS 43

AHS 43

Description

The AHS 43 is another part of the 40er movement series by August Hirsch of Schwenningen.

For a true pin lever movement, it is astonishing well made with its balance staff with pivots (not shock protected) and the indirectly driven center second, which is ruby-beared below an own cock. The long regulator arm, which sets the effective length of the hairspring is also an unusual feature for pin lever movements.

The dial side in nevertheless typical for a simple movement: The winding system is realized as rocking bar and the mainspring click is just a simple spring.

The large cutout around the escapement is very helpful for a proper service of the escapement pins.
