I do have some Seikos, still only one "5". And, OK, this crappy picture doesn't really qualify for a show-off thread ... nevertheless a crystal and a set of hands are heading this way, so let's see If I can improve!
It's actually a "Pollymod" (modded by PollyC), and is a 7017 flyback chrono. Not sure exactly what it started life as, but I believe it was a 5 so qualifies. And it does still say 5 on the dial. And I love it !:wub:
