Pebble Steel
I've been checking out some of the new stuff coming out of CES this year, and the Pebble Steel is probably the first smartwatch that offers reasonable functionality while still maintaining marginally decent looks and great battery life. Certainly, it's the first that I'd consider wearing (unless you count the Fitbit Flex, which I do wear).
The Verge has a brief write-up, but check out the video on the Pebble Steel site as well.
