Swiss made vintage hand wind timepiece to hang around the neck. Hard to date this piece but if I would guess is the 60's to 70's due to the style and lack of aging. It works and keeps time. No batteries. Wind it up each day. Nicely made and detailed. The crystal has scalloped edges and the case has a outward fan pattern. Watches in general can be very worn. This one has little wear and is in very good condition. The chain has a 12" drop. I did not find any purity of the metal so it is most likely gold tone. The clasp in a round hook eye. And they were smart when they designed the piece. They put it upside down so the user can simple lift it up to see the time.
