Watch is not working please see all pictures. This was a gift for retirement from the 1970’s. The watch and band are authentic however it’s not keeping time and the winding mechanism outer portion isn’t there. Inside the casing it looks like the seal is coming out from the bottom. It’s not the glass being cracked. Happy to answer any questions. Also I don’t know how to open the watch if you can explain it I can attempt to open and take picture of the mechanism.
