Good info OP. Thanks.
As a huge Apple guy, I've been eyeing the Apple Watch carefully but not being able to see in bright sunlight is definitely an issue for me. Makes me appreciate my Pebble a bit more - never any sun readability problems, in fact it gets better in the sun because of the nature of its screen.
Of course, the Apple Watch is 1000x more powerful (and WAY cooler!), but actually being able to see the screen outside is pretty important on the list of important things!
