Haven't whacked mine on a doorknob yet... It actually wears quite comfortably in my opinion. Of course, my usual main concern on comfort is the crown digging into the back of my hand, but there is zero chance of that happening with this model.
NICE! I have pondered this watch since they released them. I keep looking at them but can't seem to pull the trigger maybe during the next sale. I did look at a quartz chrono they have for 97 bucks but I think the auto 3 hand is a nicer looking watch.
