Went to the Apple Store to try them one today. Wow. They look and feel much better (and smaller) than advertised. The metal buckle did not look appealing to me on the site at all, but man in person, they are incredible. I would say the 42mm on the wrist in person looks like the 38mm on line. Glad I order the 42mm because the real estate jump is significant, even though we're not talking about much acreage.
