Here's the kicker...it's my birth year watch! which covered 2 desired slots on my collection, a nice birth year and a 5512. No other watch other than my 69 GMT has gone through more hands for appraisal and authentication because both are grail pieces, birth years (mine and my brothers), vintage and highly desirable and hence popular on the redial and franken market and both are expensive and collectible. So I spend a good amount on authenticating etc, but at least I know what I have. The 5512 came on a not original SS bracelet that is a few years younger than the watch itself, but being a birth year I figured I myself don't have all the original parts in me so why should it?
Back to the OP though, that is a tremendous dial although the Tritium seems to be falling off at 6 and elsewhere. also, like mine, either the bezel or the beat on the bezel is a replacement. Not that it would keep me from getting it!!
