Wrist clocks! Personally I like the 50mm size range. I didn't at first, but after a friends urging to try it for a week and then send it back I fell in love with it, and kept it. I do agree that the size across isn't as big of a deal as the height! Right now I'm wearing my new favorite thats maybe only a 45mm, but is easily 15 tall, it actually makes it harder to wear than the 50mm!
