Thanks, Bill, for posting this. I must admit not really being a Ploprof fan, mainly because of the size and thickness. Not to mention the fact that I am not a professional diver. However, when I read the article you post, it gives a new perspective. I recall many times not initially being too impressed by certain watches, but after doing a bit of research, a certain fondness emerged! As indeed it is with this article. For years, as a matter of fact, I never paid a lot of attention to the Speedmaster. However, when I found out more details and history, I ended up buying one. Even the aesthetics of the watch which didn't always appeal, soon became beautiful.
