Förster 2080

Description

The Förster 2080 is a rather early german form lever movement, which debuted in the early 1950ies. It was probably the successor of the Förster 2075. The most noteable differences to that movement are the shape of the train bridge and a cheaper constructed rocking bar winding mechanism.

The Förster 2080 uses a screw balance. It regulates a classical constructed pallet lever movement with decentral second indication. All axes are positioned around a half-circle 'round the balance wheel.

The balance is not shock protected; the effective length of its hairspring is adjusted by a long regulator.arm

On the dial side, you see the rocking bar winding mechanism, which is incomplete on the specimen shown here. At "10", there's the click mechanism, which is a very simple one here: It consists of only one part: A spring, which directly blocks the mainspring barrel wheel.

Since the mechanism is a very cheap one, it normally doesn't last very long, the spring either breaks or bents, makeing it useless. Because of this, the spring is held by a large screw and can be exchanged easily.

Technical data

Test Results

The specimen shown here, was heavily tinkered, incomplete and had screws, which were manually "blued" by a pen. Although is still ticked, it got a full service.

Timegrapher Protocol

On the timegrapher, which printed in double precision, this specimen performed poorly. All measured values were extremely position-dependent and had way too large deviation values.

Altough the former tinkerings did not break the movement, they damanged the movement.

This specimen is a good example, how the fact, that a movement ticks, alone does not testify anything about its condition.
