Why buy each?

Fitbit Edge

Larger AMOLED display with always-on option

A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.

Built-in GPS, ECG, and an altimeter

Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.

User-replaceable battery

Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.

Polar Vantage V

ECG on a sports GPS watch

Polar Vantage V3 is one of the few sports GPS watches with on-demand ECG — usually only found on lifestyle smartwatches.

Wrist-based running power

Running power measurement without a foot pod or chest strap — a significant training metric for pacing effort on hills and varied terrain.

Polar Training Load Pro

The most detailed training load analysis in any sports watch: muscle groups targeted per session, recovery status per muscle, and long-term load trends.
