It was handed down to me by my father when I turned 40, thats a long time ago.
Its solid gold in/out including bracelet.

 

That's a mid 60's to early 70's watch that's powered by a caliber 50x of some sort. The value will be tied to the gold content (14k or 18k) and whether or not it's a Longines' bracelet or an aftermarket bracelet.
