Why buy each?

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.

Garmin Fenix

Built-in speaker and microphone

First Fenix to include a speaker — enabling phone calls, Bluetooth audio, and voice prompts directly from the watch.

AMOLED or Solar: choose your battery priority

AMOLED for the best display at 18 days. Solar MIP for up to 48+ days in expedition conditions where charging is impossible.

Certified for diving, rated for mountains

EN13319 dive mode (up to 40m), MIL-STD-810 shock resistance, and TopoActive maps covering 100+ countries — the most capable outdoor watch in Garmin's lineup.
