Just got a new Garmin D2 at AOPA Summit - haven't taken it flying yet, but I already love it! The pilot watch has a WAAS GPS Receiver with Direct To and Nearest Airport functions. It features a compass, altimeter (with a vibrating alert) and a moving map. I can't wait to try it with the VIRB HD video camera, which it can control remotely.
Oh, and it also tells the time!
