I just picked up a used Series 0 Stainless Steel 42mm Space Black watch with Black Sport band. This watch was purchased only a few months ago brand new. I noticed the band is not completely tight where it attaches to the watch. A bit hard to explain but I'll try. If the watch with the sport band attached it laying in the palm of my hand, I can pick up either half of the band and lift it up and down and it moves around a tiny bit in the area where it's attached. I wasn't sure if it was supposed to be tight or wiggle around a bit. It does not come out or anything without pushing the release button but does have some play.
