Expert opinion
Who it suits: Private pilots and aviation enthusiasts who want flight tools in a premium multisport smartwatch.
The D2 Mach 1 puts a moving map with NEXRAD weather, worldwide airport data, METARs and TAFs, an HSI and direct-to navigation on your wrist, and receives flight plans from Garmin Pilot. Around that sits a full Epix-class training and health watch with maps, music and Garmin Pay.
Battery lasts up to 11 days as a smartwatch and 24 hours in the Fly activity. Weather data depends on a phone or connected avionics, and it is no substitute for certified navigation equipment, but it is a capable backup and a very good everyday watch.
