I've been looking for a good, everyday watch and the Sinn 556I is one my favorites that I have come across. Although the 556A is nice, I prefer the dial without the numerals. Although I really like this watch, I have some concerns. I know that the 556I is the entry level model and therefore does not have the hardened case and other stuff. My question to the owners of either the 556I or 556A is how does your stainless case hold up? I own a cheap Victorinox quartz watch that I wear everyday that is just untreated stainless steel and I've banged this watch around a couple times and the case has some slight wear and small dings but nothing that really bugs me so I can't image the Sinn would be any worse, especially since I wouldn't wear the Sinn in those types of situations where there is the possibility of damaging the watch. So let me know your thoughts, I see that there is a 556 thread that appears to have many happy Sinn 556 owners so this watch can't be bad by any means but this purchase would have to be done right.
