Nice watch! The dial is very nice.
I know 100% what you are talking about. Had the same situation with my Sinn 556. I fell in love with the watch and bought one with the original silicone strap from Sinn. But it looked weird on my wrist and I had the feeling that it wasn’t the right watch for me. But then I changed to a grey Nato strap and I immediately liked the look, the feel, everything…
It is so interesting how much the strap influences how a watch wears and looks that it is strange that most people never change the strap on their watches.
