I have a golden Zodiac watch (serial number 1022972 at the back of the watch) for a very long time.
It was given to me by my late mother.
She got it from her grandmother.
I would like to ask these 2 questions so as to give my sister-in-law an answer:
How old is my watch?
How much is it worth?

Thanks.

Please post some pictures of it, front and back.
