Looking again at classic Speedmaster professionals and 41mm Railmasters. I prefer no-date watches. Like the history and tradition of the Speedmasters. And the 41mm Railmaster is a real classic! (the way Rolex should do the Explorer). My brother was visiting with me this last week, flying in from Botswana, and had the Seamaster I gave him a couple of years ago (after I had worn it a couple of years), and I forgot what a great watch that was!
