Garmin has announced the D2 Delta aviation watch, expected to be available in August and coming in 3 varieties. The new watches appear to be based on the new Fenix 5+ platform; D2 Delta PX (Fenix 5X+), D2 Delta (Fenix 5+) and the D2 Delta S (Fenix 5S+) and thus have all of the features of the Plus series, including on-device streaming music and Garmin Pay.
On the aviation side there are some new aviation features: notifications for pressure altitude, cross track errors and fuel tank timers. Plus the larger Delta PX will have wrist-based Pulse Ox to help monitor oxygen saturation levels (only available on the Delta PX).
