I purchased this watch from a watch repairman's shop I somehow managed to walk into (I think it was the site of him working on a tiny little lathe as I glanced in the window that made me want to see what he was doing) in Pittsburg, PA back in the late 80's for $25 I believe. It ran then, and even though it spends most of it's life in a box, every time I wind it up, it runs and keeps time just fine. I ran across it in my safe the other day, and would like to know as much as I can about it. I have searched the web and have not seen another model exactly like this one. If I had to guess, I would say it most closely resembles an Academy Award model, but not exactly. Please feel free to correct me on any statements I have or may make where this watch is concerned as I know nothing about it, except that it really caught my eye and has now caught my 12 year old son's eye as well. I would consider a new old stock dial if anyone here has one, and a glass crystal as well (if that was ever an option).
I would have thought it an older style than 1963, but according to the back that is on it, the M3 designates 1963.
updated case dimensions: 35.6mm lug to lug x 28.6mm without crown. (28.6mm without lugs)
