The Polar Vantage M3 adds wrist ECG, offline maps, dual-frequency GPS and a 1.28-inch AMOLED touchscreen to Polar’s Vantage M multisport line. Polar also lists SpO₂, skin-temperature and optical heart-rate sensing; its manual gives different battery estimates for different modes, so there is no single runtime figure that applies to every use.
Polar announced the watch on October 23, 2024. The specifications and performance estimates below are Polar’s published claims; the research for this article did not establish independent testing.

Does the Polar Vantage M3 have ECG?
Yes. Polar lists wrist ECG among the Vantage M3’s features. The available research establishes that the watch offers ECG measurement, but does not establish claims that it detects atrial fibrillation, gives medical diagnoses, or feeds ECG data into particular recovery or readiness features. Treat it as a watch measurement, not a medical conclusion.
Polar also lists SpO₂, skin-temperature and optical heart-rate sensing. The dossier does not establish additional medical capabilities or specific effects of these sensors on training decisions.

Does Polar Vantage M3 have offline maps?
Yes. Polar says the watch supports offline maps, with North America and Europe maps described as preinstalled. Additional regions can be downloaded through Polar Flow. Polar’s feature description presents maps as a navigation view used with planned routes and breadcrumb tracking.
To use a route, prepare or import it in Polar Flow and sync it to the watch. Check Polar’s current guidance for supported map regions and route options before relying on the watch for a particular trip. The research does not support claims that the M3 provides turn-by-turn prompts or automatic rerouting.

AMOLED display and dual-frequency GPS
The M3 has a 1.28-inch AMOLED touchscreen with a resolution of 416 × 416 pixels, according to Polar. It also offers dual-frequency GPS. Polar’s manual says its average route-accuracy figure is 5 m in open-area satellite conditions without buildings or trees blocking the view; it cautions that conditions such as urban or forest cover can cause variation. This is a manufacturer figure, not an independent test result.
How long does the Polar Vantage M3 battery last?
Battery life depends on the selected mode and settings. Polar’s manual gives these maximum estimates for specified configurations; they are not directly interchangeable because the GPS mode and recording settings differ.
