Defective Apple Watch socket?

Hi,

I've had my Nike + watch since release. I've noticed that the sports band (whilst not necessarily loose) moves when connected.

At a certain angle when holding the watch, the band wiggles from side-to-side. It appears that I can also move the band up and down. It appears that the strap has room to move when connected despite still feeling secure enough to not disconnect.

Is this normal? To be able to move the band around when it is not on wrist? It definitely feels secure but there is room for the band to move when not on wrist.

Thanks for any help.
