Have had my Watch for a few days now and it's awesome! I was even able to dabble in the digital touch feature. I sent a buddy of mine my heartbeat, which I understand to be your actual heartbeat. But when sending a heartbeat, the green LEDs on the back don't shine! I also took my pulse manually to see if they match up, which they didn't at first. Is this truly your heartbeat for that exact moment? edit: The watch doesn't even need to be on your wrist to send a heartbeat... Calling BS on this feature!
