One of my friends presented me this for my birthday, he got it from a friend of his that owns a Jewelry store in my area, the 4th generation of family ownership. It was worn by the current owner for quite awhile. I'm going to go meet this jeweler soon,find out when he bought it.
I got out my loupe magnifier, can't find the date code, it should be right below BULOVA on the caseback.. The other stampings on the back are not worn ,so the date code seems missing . How odd.
