Citizen 2340A

Description

This is a tiny ladies’ watch movement with indirect driven center second.

Movements of this shape with center second are pretty rare, since they require a complex construction with two plates because of the reduced size.

The filigrane Citizen Parashock 3 shock protection system can be seen here very well. Not many systems are that filigrane than this one.
