Saw a new metal Pebble watch yesterday and was actually shocked to discover it was both smaller and thinner than my own analog watch, which isn't particularly big or chunky.
It looks like a calculator watch for the 21st century.
(But I guess given that I don't like watches much it isn't surprising I don't find these devices very interesting)
Edit: Adding maybe a little bit of value to this comment, the function of the device is very apparent in it form.
