The third one is the ref. Bruce Lee wore the last few years of his life. I expect they might become more popular like the Pogues. The last one, more modern, is way big for me but it was part of the deal. I'm excited to get the Accutron and wear it regularly. It's 40mm, which for 1969 was a very large watch. I'm curious if anyone has had any experience attempting to lightly scrape the indices like those on the brown dial watch. They are obviously not attractive. I am wondering if that discoloration is mostly just on the surface or if it goes deeper. I'd consider having it re lumed.
