Got this accutron on eBay recently. I serviced the watch and completely restored it. It is obviously some form of Accutron date, but I don't know what model it is. It has a nice stainless steel case and a simple silver burst dial with a line running from 9 to 3. I put it on a vintage rubber dive strap and I think it suits it well. It's a nice watch that runs just as good as it looks.
Case Serial No.
