Polar Vantage V3 is one of the few sports GPS watches with on-demand ECG — usually only found on lifestyle smartwatches.
Running power measurement without a foot pod or chest strap — a significant training metric for pacing effort on hills and varied terrain.
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's signature energy monitoring tracks stress, sleep, and heart rate variability to give you a daily 0–100 energy score — more nuanced than raw step counts.
The Venu 3 automatically detects when you nap during the day and logs it accurately in your sleep data — a unique wellness feature among smartwatches.
Most AMOLED smartwatches last 1–2 days. Garmin's efficient software architecture stretches the Venu 3 to 14 days — a huge practical advantage.
