Garmin Forerunner 570 vs Polar Vantage M3: Maps or Music?

The Polar Vantage M3 is the better buy for athletes who put training and navigation first. These two established multisport options take different approaches: Polar favors long recorded outings and maps, while Garmin offers more everyday convenience and a bigger display. This comparison uses the 47mm Forerunner 570; its figures do not describe the smaller 42mm version.

Key Differences

• Everyday battery: Garmin claims up to 11 days in smartwatch mode; Polar claims up to 7 days.
• GPS endurance: Polar claims up to 30 hours in performance training mode. Garmin claims 18 hours with GPS only, falling to 14 hours with all satellite systems and multi-band enabled.
• Navigation: Polar provides offline maps. The Forerunner 570 offers course following without full onboard maps.
• Smart features: Garmin adds contactless payments, stored music, and calls through a paired phone. Polar offers phone music controls and notifications.
• Display and fit: Garmin has a 1.4-inch screen in a 47mm case; Polar uses a 1.28-inch screen in a 44.7mm case.

Deep Dive Comparison

Design & Comfort

The Garmin weighs 50g with an aluminum bezel and fiber-reinforced polymer case. Polar uses a stainless steel bezel and polymer case, weighing 53g. A 3g difference gives little reason to choose either watch; the larger Garmin case is the more useful fit distinction.

Garmin’s 1.4-inch AMOLED display gives workout fields more room than Polar’s 1.28-inch AMOLED. Resolution is 454 x 454 pixels versus 416 x 416 pixels, respectively. Choose Garmin for screen space, or Polar if a smaller case sits better on your wrist.

Battery Life

Garmin wins between workouts, with up to 11 days of smartwatch use against Polar’s 7 days. Those are manufacturer ceilings, not promises for a week filled with GPS sessions and an always-on screen.

Polar wins for sustained recording. Its 30-hour performance-mode rating provides substantially more headroom for long events than Garmin’s 18-hour GPS-only rating. Garmin’s battery specifications drop to 14 hours with multi-band tracking, so do not treat 18 hours as its highest-accuracy endurance figure.

The GPS chart compares published modes, rather than identical test conditions. Polar’s figure is its performance training rating; Garmin’s is GPS-only.

Health & Fitness Features

Both watches include optical heart rate, blood oxygen sensing, a barometer, and multi-band GPS. These specifications do not establish a heart-rate accuracy winner. Fit and movement affect wrist readings, so athletes who pace intervals by heart rate should consider a compatible external sensor.

Polar adds wrist ECG and overnight skin-temperature tracking. The Forerunner 570 does not support Garmin’s ECG app: Garmin identifies that feature as exclusive to the Forerunner 970 in this pairing’s launch announcement. Polar’s ECG is a training and wellness feature, not a reason to buy the watch for medical diagnosis.

For exploring unfamiliar routes, Polar has the stronger practical advantage. Its offline maps show surrounding roads and terrain, giving you more context than a course line alone.

Smart Features

Garmin is the clear choice for leaving more tasks on your wrist. It supports stored music, Garmin Pay, and a microphone and speaker for calls through a compatible paired smartphone. Payment support still requires a participating bank and card.

Polar handles notifications and controls music playing on your phone. Its 32GB storage does not mean it works as a standalone music player. Garmin also offers ANT+ alongside Bluetooth, useful if your existing training accessories require ANT+; Polar uses Bluetooth LE.

Price & Value

The supplied reference prices are $549.99 for Garmin and $349.95 for Polar, a $200.04 gap. These are comparison benchmarks, not confirmed current street offers; check the actual selling price before buying.

At that gap, Polar is the stronger training purchase. Garmin earns its premium through several useful differences: a larger display, longer everyday battery life, stored music, payments, phone-connected calling, and broader connectivity. Pay extra when you expect to use that combination regularly.

The Verdict

Buy the Polar Vantage M3 for training value, offline maps, and longer GPS recording. It is our overall winner at the reference prices, especially for runners and hikers whose outings stretch well beyond a normal workout.

Buy the Garmin Forerunner 570 if you want a larger screen and regularly use wrist payments, stored music, or phone-connected calls. Its longer smartwatch battery and ANT+ support give existing Garmin accessory owners further reasons to spend more.

Frequently Asked Questions

Which watch is better for most runners?

The Polar Vantage M3 is our value pick because it combines multi-band GPS, offline maps, and longer training battery life. Choose Garmin when its music, payments, larger screen, and everyday battery advantage justify the extra cost.

Does the Garmin Forerunner 570 have ECG?

No, the Forerunner 570 does not support Garmin’s ECG app. The Polar Vantage M3 offers wrist ECG, but shoppers should not treat it as a medical diagnostic device.

Is the Garmin worth roughly $200 more?

Yes, if you will regularly use its stored music, payments, phone-connected calls, and larger display. For buyers focused on recording workouts and following unfamiliar routes, Polar offers better value at the supplied prices.

Which watch is better for long hikes or endurance events?

Choose Polar for its offline maps and up to 30 hours of performance training battery life. Garmin’s longer smartwatch rating does not carry over to GPS recording, where its rating is lower.

Can either watch play music without a phone?

Garmin supports onboard music playback, so you can listen through compatible Bluetooth headphones without carrying your phone. Polar provides controls for music on a paired phone; its larger storage capacity does not give it standalone music playback.
