Mea Culpa: Nike GPS watch not too small

I was in the San Francisco Niketown store in part to see if they had the GPS watch. They did have one, in the box, in a lucite display box. I asked to check it out, which I did. It was a return, and it was the only one they had, as they were apparently in great demand. This watch was much bigger than the 25mm described by an eBay seller. It's maybe around 40mm across the front and very thick, I assume to tuck away the GPS stuff. I could have bought it for the $200, and maybe even sold it on eBay for a few extra bucks as I noticed it's been selling for higher. But I decided to do nothing. I guess I'll have to put it back on my list.
