I picked this up recently at an auction. This is the first generation model created for the 1964 Olympic games in Tokyo. Lots of good information on these references can be found here. The auction photos showed a nice dial, but I was unsure of the case condition. It turns out to be in pretty good shape, with well-defined edges. The inner bezel ring rotates as it should, which is a handy little feature. The Olympic torch etching on the case back is still visible but pretty worn down, which appears to be common. In my opinion, it's a well-proportioned watch: a good size with some interesting dial elements, but things don't feel too crowded. And I quite like the legibility of the dark gray dial. I've been trying some different strap options. Leaning towards the beads of rice bracelet at the moment, but I think a bonklip bracelet might work here as well. I think it's a keeper and will probably look to have it serviced soon.
