Comments about the data
Not for Sale!
The movements presented in this caliber finder are not for sale. This is only a data sheet for identification and evaluation of the movement calibre, as well as for approximate dating. The features and technical data were mostly taken from movements, which were investigated on the occasion of sale, service, or repair. As the accordant watches are no longer available, further data can't be given on request.
