I think their great , I've ordered a Stainless bracelet one because the straps are crap that they come with , and I also have read that their hard to remove when replacing.
i had the chrono and i can vouch for the shitty strap. looks real bad. and it's difficult to source a gen or aftermarket strap. gens anre like $450.00 i think. so...i would go with the stainless as well. the only other consideration is the size. the 100 chrono seemed huge and ungainly on my 6.5" wrist. however 44mm and 45mm pams feel just fine. santos 100 (at least the chrono) is a big bulky heavy beast. imho anyway. i ended up giving mine away.
it sure was a nice rep though
