Hey now. Soooooo do you guys care if the buckle or clasp on your aftermarket strap is not the one that came with your watch? I have a Speedy 3513 and really want a nice python strap for it. I love the steel, don’t get me wrong, but sometimes a change is in order. To be honest, the python/exotic leathers may just be a phase for me, but I want to enjoy that phase. I also have a Ball Fireman NECC that I wear every day. It takes a beating. I can’t wait for the day I can get a Sinn and see how they compare, but for the time being the watch strap on the Ball is not the most comfortable. So that needs a changing too
