Expert opinion
Who it suits: Pilots who want comprehensive aviation tools, a larger AMOLED screen and a built-in flashlight in one watch.
The D2 Mach 1 Pro moves to a 51mm case with a bigger 1.4-inch screen, adds MOS and meteograms to the aviation weather, and brings an LED flashlight that is genuinely useful for pre-flight checks in the dark. The ECG app and Training Readiness join the health and training tools.
Battery jumps to 25 days as a smartwatch and 46 hours in the Fly activity, nearly double the Mach 1’s flying time. If you can live with the larger size, it is the more complete watch.
