I'm not extremely knowledgable about the watch or vintage watches in general. I had to sell my Dad's 1967 Speedmaster for estate purposes, so have been intrigued ever since. I picked up the attached watch at a local auction. It was more or less a last minute purchase. Wanted to get everyones thoughts on authenticity. It does have a scuff on the crystal and dial(which I didn't notice at the auction...rookie mistake).
