Lightly used Garmin D2 Aviation Watch. Has a tiny nick on the face, barely noticeable. Comes with USB cable for charging and data sync. Works for fitness tracking as well as flight tracking. Fighter playback ranges from unusable to slightly worse than ACMI. I imagine it would be awesome in a heavy aircraft. Has WAAS, can interface via Bluetooth to your EFB. My favorite feature is the customize-able cabin pressure altitude warning, works for ascent and descent. The nice thing about this watch vs the D2 Bravo or D2 Charlie is that it can operate completely stand-alone (ie without your phone).
