Just tried the watch like that, and it worked out great, it pulls my vitals. To the Psychopath comment, I don't know why this guy does it, other thanhe's driving a lot ? I rotate mine quite frequently when im on my motorcycle ( sports bike ) because it's often times not easy to pull the one hand up to check a map, or see my speed ( GPS Speedometer app ). So i wear it on my wrist when i ride so i can just tild up a bit, i tried it with it on top, but the glare of the sun makes it very hard to read, and I have a very very dark shield, almost black!
