Apple will also need to rethink their hatred of buttons. Messing around with a touch screen watch in the dark or trying to activate one function and not another is not particularly enjoyable when a watch is controlled with precise swipes and touches. Buttons around the edge of an iWatch will increase people's ability to control the watch in a more tactile manner versus having to look at the watch all the time. Legibility will be a major factor in whether consumers purchase the iWatch as a mere novelty or more deeply incorporate it into their life. A careful study of the world's most popular watches will surely aid Apple in understanding what good legibility means.
