Here a couple of vintage manual wind ladies watches with the same movement, 1520.
The “marbled” green dialed watch is reference 1520-3669. It case dimensions are 13mm x 39mm. Its unusual dial color and rectangle shape and faceted crystal give it a distinctive personality. IT DOES RUN A LITTLE FAST. I have tried to demagnetize it a couple of times. The performance has improved, but is still a little fast. The integrated bracelet is in lovely shape and the security chain is still intact.
The blue dialed watch is reference 1520-3629. Its case is 14mm x 29mm. This one keeps accurate time. The brushed, stainless steel is in very good shape and the security chain is still intact.
I will try and get as many pictures as possible.
