AHS 152


The manufactury AHS (Alfred Hirsch, Schwenningen, Germany) was famous for mass production of simple pin lever movements. The caliber 152 described here, was made in the fifties and was a very nice exception, since it was a true pallet anchor lever movement.

Although it uses a service unfriendly pier construction with one single plate and on the dial side only a rocking bar winding mechanism and a simple flat click spring, it is equipped with a screw balance with regulator arm and a block for the indirectly driven center second hand. The balance runs in two trishock-like shock protection systems.
