SEIKO 6105-8000 Automatic Diver June 1970 -- Very Nice!
Up for sale is a 6105-8000 "proof/proof" model that is in very nice condition. It runs and keeps time and is very clean overall. It is about -120 seconds/day, so it is highly recommended that it be serviced. Also, it is all original except the crystal, which I replaced myself. However, these older pressure bezels were poorly constructed since they require a spring wire underneath it to keep it from turning loosely. They are a PAIN to get back in, and I was unable to do it. So, when you have it serviced you will also need this done properly (original crystal and wire included).
A stunning example, bright hands, even some lume in the dark, but not much. Comes on an Uncle Seiko Tire Tread strap.
