Ha. Yes, it is big. But the guy in that video also has an extremely skinny wrist.
I think this is a necessary compromise if you want a usable screen, although I suppose the band does not need to be so wide.
Is the Vapirius model a Windows interface? It has a metro look to it. Doesn't look like an Android.
The Pearl/Omate also looks inelegant on a skinny wrist because it is so fat. At least, the Omate guy (LePen) does not look very sexy that watch on his flimsy little boy wrists.
