Here's the other watch I picked up today- a Cal. 320.The serial number is 19XXXXXX which would date it to 1962-63. There are no markings on the back. The inside of the caseback states 101.009-63. For those familiar with this watch, does it look above board?
I also wanted to find out about the bracelet. Is this the original bracelet. The markings on the clasp of the bracelet is "Omega 198.0031". I've never encountered these markings before.
Hope to get feedback from anyone familiar with this. Thanks
