> Glancing at a watch is essentially the same as glancing at a phone

You can't just "glance down at your phone", you have to take it out of your pocket first, and unlock it in most cases. Your watch is already in your peripheral view and very little effort is required to position it correctly and look down at it. I recently received my Pebble (http://getpebble.com) watch and you'll have to take my word for it. Being able to glance down at my watch to see text messages and caller ID's is much more natural and fluid than pulling my phone out of my pocket; especially when I'm sitting down.
