yup, I already have a black seiko diver, a somewhat less common version with the "block" hour markers and the jubilee band. Yeah, unregulated.. running 10+ sec/day
I just adjust monthly. If I get it serviced, I am going to get that fixed, I know alot of them run fast though.
The old one is still running strong, but wanted another to put on a rubber divers strap. The new one from O is the red/blue version. (I keep them in a timed/automatic bidirectional winder)
