Garmin HRM 600 vs Polar H10: Worth $80 More?

Both of these are chest straps, not watches, and both give you the accurate heart rate data that wrist sensors can’t touch. But they aim at different buyers: one is a do-everything strap for the Garmin faithful, and the other is the cheap, universal standard that just works.

Here’s the short version before we dig in: the Polar H10 is the smarter buy for most people, and the Garmin HRM 600 earns its price only in specific cases.

Key Differences

• Price: The Garmin HRM 600 runs $169.99. The Polar H10 launched at $89.95 and often sells around $80 — roughly half the cost.
• Running dynamics: The HRM 600 measures cadence, ground contact time, vertical oscillation and stride length. The H10 tracks heart rate and heart rate variability, not running form.
• Battery type: Garmin uses a rechargeable battery good for about 2 months per charge. Polar uses a replaceable CR2025 coin cell rated for 400 hours of use.
• Standalone recording: The HRM 600 can record an activity on its own, no watch needed. The H10 stores just one training session in memory.
• Compatibility: The H10 broadcasts over Bluetooth, ANT+, and 5 kHz GymLink, so it pairs with practically any watch, app, or gym machine. The Garmin plays best inside the Garmin ecosystem.

Deep Dive Comparison

Design & Comfort

The Polar H10 is a known quantity: a 60-gram pod on a textured strap that stays put during sprints and burpees, with a case built from a mix of ABS, glass-fiber ABS, polycarbonate, and stainless steel electrodes. Garmin hasn’t published a weight for the HRM 600, but it follows the same slim-pod-on-a-strap formula. Comfort between the two is close enough that it won’t decide your purchase — both disappear once you cinch them under the sternum. Fit matters more than badge here, and both use standard replaceable straps.

Battery Life

This is where the two straps play by different rules, so read the numbers carefully. Garmin’s “up to 2 months” is a rechargeable claim under typical use. Polar’s 400 hours (about 16.7 days) is pure active recording time on a coin cell you replace rather than recharge. If you train an hour a day, that Polar cell lasts well over a year before you swap it.

The honest takeaway: Garmin wins on the raw calendar-time chart, but the Polar’s replaceable battery means zero downtime — you’re never stuck waiting for a charge before a workout.

Health & Fitness Features

Accuracy is a wash, and that’s a compliment to Garmin. The Polar H10 is the strap researchers and reviewers use as the reference for “correct” heart rate, thanks to its ECG-based electrodes and accelerometer. The Garmin HRM 600 matches that chest-strap-grade heart rate and then piles on extras: heart rate variability and full running dynamics — cadence, ground contact time, vertical oscillation, and stride length. If you’re a runner chasing form data, the Garmin gives you numbers the Polar simply doesn’t collect. If you only care that your heart rate is right, they’re even.

Smart Features

Neither strap does music, payments, or notifications — that’s not their job. What matters here is how they talk to your other gear. The Polar H10 is the connectivity champ: Bluetooth, ANT+, and 5 kHz GymLink all at once, so it links to a Peloton, a Garmin watch, an Apple Watch app, and Zwift without drama. The Garmin HRM 600 counters with standalone activity recording — it can capture a whole session by itself and sync later, which is genuinely useful if you’d rather run without a watch. Different strengths, and your setup decides which one you’ll actually use.

Price & Value

At $169.99, the Garmin HRM 600 is a premium accessory. The Polar H10 at $89.95 (often near $80 on the street) delivers the same trustworthy heart rate for roughly half the money. Unless you specifically need running dynamics or watch-free recording, that price gap is very hard to justify.

The Verdict

The Polar H10 is the winner for most buyers, and it isn’t close on value. You get the same benchmark-grade heart rate accuracy as the Garmin, it pairs with literally everything you own, and it costs about half as much. Buy the Polar H10 if you want one strap that just works across your watch, your gym bikes, and your training apps without paying a premium.

Buy the Garmin HRM 600 only if two things are true: you run with a Garmin watch, and you actually want running dynamics like ground contact time and vertical oscillation — or you want to record workouts with no watch at all. In that narrow lane, the extra $80 buys real features. For everyone else, the H10 is the strap to get.

Frequently Asked Questions

Which is better, the Garmin HRM 600 or the Polar H10?

For most people, the Polar H10 — it delivers the same trusted heart rate accuracy for roughly half the price and connects to almost any device. The Garmin HRM 600 is only “better” if you specifically need running dynamics or watch-free activity recording.

Does the Garmin HRM 600 track running form data the Polar H10 can’t?

Yes. The HRM 600 measures running dynamics — cadence, ground contact time, vertical oscillation, and stride length — plus heart rate variability. The Polar H10 sticks to heart rate and HRV and does not capture running form metrics.

Is the Garmin HRM 600 worth almost double the Polar H10’s price?

Only for a specific buyer. If you’re a Garmin runner who wants form metrics and standalone recording, the $169.99 price is justified. If you just want accurate heart rate for your watch or apps, the $89.95 Polar H10 gives you the same core accuracy and saves you around $80.

Will the Polar H10 work with my Apple Watch, Peloton, or Zwift?

Yes — that’s its biggest strength. With Bluetooth, ANT+, and 5 kHz GymLink, the H10 pairs with Apple Watch fitness apps, Peloton bikes, Zwift, and Garmin devices alike. It’s about as universal as a heart rate strap gets.

Can either strap record a workout without a watch or phone?

The Garmin HRM 600 can — it records a full activity on its own and syncs later, which is handy if you’d rather train without a watch. The Polar H10 only holds a single training session in its internal memory, so it’s not built for regular watch-free logging.
