I wear a Garmin D2 Pilot.
If you’re into piloting and like your watches as cool as possible, look no further than Garmin’s D2 Pilot watch ($449). Even in the crowded field of complex digital flight watches, the D2 stands out with a truly amazing set of features. Sporting an accurate WAAS GPS receiver along with an altimeter and compass, the 49mm-wide D2 can manage direct-to and nearest routing via an on-board worldwide airport database. Speed, waypoint, flight plans, ETA, active mapping, bearing and glide ratio are all available, along with a view of up to six time zones. It can even communicate with a number of external Garmin devices to keep additional flight information ready at a glance. It’s a remarkable, pure flight tool.
