Two decades ago I bought the vintage watch on the photos. I like it and wear it now and then (I am a man). It is very conspicuous and bigger than many lady watches. Although I have some idea, I would like to find the exact manufacturing date and have input for the approximate value. Could it be a one-off model? The total thickness of the movement (together with the 2 glasses) is about 3 mm. It is always visible from top and bottom. Click on photos to magnify.
Thank you for any information.
