Estate find: A vintage A. HIRSCH SWISS COHARD PERPEX 17J wind-up Watch ( Missing Glass Crystal)

It has a metal necklace/ fob attached.

When I found this, it was missing the glass crystal.

I did wind it up , and the movement seems to be running ( see video).

It may need a proper service from a watch person.

The porcelain(?) face has a few age cracks, but just a cosmetic issue.

The case shows typical age use, some scratches, etc

The winding knob works.

Sold as is
