Citizen 5800

Description

This movement is a rarity - it is one of the smallest ever produced electromechanical movement. In contrast to many of its rivals, it works without electric contacts, since the coil is statically on the plate, while the permanent magnet is located on the balance.

Movements of this type were produced for a very short peroid of time only, in the middle of the seventies, before they were replaced by the mechanically much simpler quartz movements with stepper motor.
