Serious endurance athletes — particularly runners and triathletes — who want Polar's unmatched training load science and recovery guidance, combined with ECG health monitoring and running power in a premium package.
Key strengths
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.
The Polar Vantage V3, released October 2023, is Polar's flagship sports watch — featuring ECG, wrist-based running power (no chest strap needed), multi-band GPS, AMOLED always-on display, and Polar's industry-leading training load and recovery analysis. At 8 days battery, it's the most analytically sophisticated Polar watch ever made. Polar's US list price is now $699.99.
Both have ECG and wrist-based running power. Garmin FR970 has longer battery (15 days vs 8), full topographic maps, a built-in LED flashlight, and a more polished ecosystem, at $749 against the V3's $699.99 list price. For training science depth, Polar. For maps and battery, Garmin.
Basic breadcrumb trail navigation but not full topographic maps like Garmin or COROS. If full maps are essential, choose Garmin FR970 or COROS Apex 4.
The Vantage V3 is 3 years old and past its previous cycle length, but Polar has not announced a Vantage V4. Polar's US list price has risen to $699.99, so the V3 is only good value at sale prices. If timing is flexible, watch for a Polar announcement.
Yes — it supports swim, bike, and run with automatic sport detection and full multisport mode. Running power works across disciplines, and Training Load Pro tracks recovery across all three.
Yes — it pairs fully with both iPhone and Android via the Polar Flow app. All training analytics, sleep tracking, and health data sync to both platforms.
