The 38mm is TINY

Yep it is really small, just been playing around with it - glad I went for the 42

Have to agree, having clapped eyes on them this morning, they both look smaller than I had anticipated. It's a good thing though, I was afraid it would look a bit oversize and clunky like the moto 360.

I agree.
We went to the store and even the sales rep got it wrong. Demond a 38mm for us which I thought was fairly small, then after when going to get the 38mm out said "oh, sorry I was wrong, that one was the 42mm, this is 38mm" It was tiny.
Still, the wife was happy with her choice.
