This is one of the few vintage Seiko watches that I currently own, Seiko 150m Diver 6309-7040 from the early 1980s. This is the original Seiko Turtle diver. The watch is one of the first ISO few certified divers around and this is why the depth rating is clearly stated on the dial. I procured this sixteen or so years ago at a flea market in Ipoh, Perak at a real bargain.
