Today I got the watch from John with the unusual dial that he bought from Ramon. The well worn 7N36-6A29 200m diver. The only thing that makes any sense is the little figure in the circle with the G in it looks like a tiny Seahorse. A symbol Seiko has used before but notice also that it has a copyright mark on the symbol which I can only guess has something to do with the HI-7 underneath the logo. As to the date and location it must be the date of some sort of important date. Here is a good picture of the dial.
