Garmin vs Amazfit

Why these two watches, and not a brand-wide verdict

“Garmin versus Amazfit” is not answerable at the brand level, because the two catalogs barely overlap in price. Garmin sells watches from under $200 to over $1,000. Amazfit's flagship costs about what Garmin's entry-level lifestyle watch costs. A comparison that sets a $1,000 fēnix against a $300 Amazfit tells you nothing except that money buys things.

So we picked the only honest matchup: the two watches that carry the same manufacturer list price of $299.99. Garmin states that figure in its own vívoactive 6 press release; Amazfit states it on its own Balance 2 page. Street prices move below both, and the live numbers on this page come from the price layer rather than from us, but the list prices are identical and that is what makes the comparison fair.

Everything that follows is the makers' own published material plus the published validation record. Neither watch has been in this building. Nobody here has run either battery down or compared either track against a surveyed route, and where we quote an endurance figure it is labeled manufacturer-stated because that is exactly what it is.

Round one: the spec sheet, which Amazfit wins and it is not close

We should say this plainly before the rest of the page complicates it. At $299.99 list, Amazfit publishes four things Garmin does not publish at all:

Read the first row again, because it is the one most reviews get wrong by omission. Garmin's battery table for this watch, in Garmin's own owner's manual, has exactly five rows: smartwatch, battery saver, GPS only, all satellite systems, and all satellite systems with music. There is no all-systems-plus-multi-band row. That absence is not an oversight in the documentation — it is how you read a spec sheet for a receiver generation. Garmin publishes a multi-band row for every watch that has one, including the lifestyle Venu 4. The vívoactive 6 does not get one because the hardware cannot run that mode.

The Amazfit, at the same list price, states dual-frequency reception across six constellations. On hardware for positioning, that is the better receiver on the only evidence either company offers: their own specifications.

And the endurance figures are not a fluke of measurement

Amazfit states 33 hours in its dual-band mode against Garmin's 17 in its single-frequency all-systems mode. We carry each maker's accuracymode rather than its flattering one — the same rule applied to every watch on this site — so this is roughly the least favorable framing Amazfit could ask for, and it still states nearly double. The cost arithmetic follows from it:

• Garmin vívoactive 6: $17.59 per manufacturer-stated GPS hour, in all-satellite-systems mode.
• Amazfit Balance 2: $7.27 per manufacturer-stated GPS hour, in dual-band Accuracy GPS Mode.

Both are computed at page load from live listing prices divided by the makers' own stated hours. If a price is stale the arithmetic is withheld rather than guessed, because a derived number built on a remembered price looks more trustworthy than an estimate while being exactly as invented.

Round two: who has ever checked any of it

Here is where the page turns over, and it is worth being precise about the shape of the difference, because the obvious version of this argument is false.

The false version:“Garmin is validated, Amazfit is not.” No. No independent validation of the vívoactive 6 exists that we could find — not of its optical heart rate, not of its sleep staging, not of its positioning. On our evidence hierarchy this Garmin sits at manufacturer specification, which is two tiers below where a reader assumes a market leader sits.

The true version: Garmin has appeared in the literature at all, and Amazfit has not. Two Garmin watches were among the eight tested against a trundle wheel accurate to 1 cm by Gilgen-Ammann, Schweizer and Wyss (2020). A Garmin device was one of the five wearables worn against a single-lead ECG reference across 536 nights by Dial et al. (2025). We could find no Amazfit device in either, nor in the Brigham and Women's polysomnography comparison, nor in anything else we were able to read.

And Garmin's record, when it does appear, is not flattering. The Garmin finished last of the five deviceson nocturnal HRV agreement in Dial et al. The 2020 GPS study predates the dual-frequency receivers now standard, so it describes brand engineering history rather than any watch currently sold — a caveat we attach every time we use it. So the honest claim is not that Garmin's numbers have been proved good. It is that Garmin's numbers are the kind of thing third parties test, and the results are public whether Garmin likes them or not.

The one place Amazfit does worse than silence

A brand with no validation record is the normal state of this market, not a scandal. Most devices we rank sit at the bottom of the hierarchy. What moves Amazfit below that floor is a specific editorial choice on its own website.

Amazfit publishes an FAQ page titled “How accurate is the GPS on the Amazfit Balance 2?” — exactly the right question. Its answer is the phrase “industry-leading GPS accuracy”, supported by the dual-band hardware claim and a promise of a connection that works “even under tall buildings or trees”. There is no methodology on the page. No reference instrument. No measured figure. No named test. No comparison set.

That is a superlative accuracy claim with nothing attached that anyone outside the company could check, and it is the reason the Balance 2 scores 2.5 on evidence here — half a point below what we give a maker that simply says nothing. Silence is honest. A ranking claim with the method removed is the thing this site was built to flag, and we apply that rule to the brand we like as readily as the brand we do not.

Round three: the strap, which is the whole ballgame for data quality

If you have read anything else here you know where this site lands on wrist optical heart rate. The 2025 placement study put 28 people through rest, cycling, burpees and a treadmill ramp with a Polar H10 chest strap as the reference, and the wrist was the worst position tested. The single largest improvement available to anyone's training data is not a newer watch; it is a strap across the chest, for well under a third of either watch's price.

Which makes the next fact decisive. Garmin's vívoactive 6 manual documents pairing wireless sensors “using ANT+ or Bluetooth technology”, names the HRM 200, HRM 600, HRM-Fit and HRM-Pro series specifically, and tells you to use ANT+ rather than Bluetooth if you want running pace and distance from the strap. A $299 Garmin can be told to stop guessing your heart rate.

Amazfit's Balance 2 page, which we read in full, does not mention external sensor pairing anywhere. It does not mention ANT+. Its only Bluetooth references are phone calls and phone pairing. We are stating an absence in the documentation, not a defect in the hardware — the watch may well pair a strap, and if Amazfit documents it somewhere we did not reach, we will correct this page. But a buyer who needs that capability cannot confirm it from the maker's own product page, and on a site that treats published documentation as the evidence, an unstated capability cannot be scored as present.

Two more absences on the same page, recorded the same way: VO2 maxis not named anywhere on Amazfit's Balance 2 page, while Garmin's manual carries a VO2 max topic for this watch; and no route out of the Zepp app — no export, no named third-party service — is described. Whether a wrist VO2 max estimate is worth having is a different question, and we have measured answers to it on VO2 max accuracy by device.

What each watch is actually for

The Amazfit case, stated as strongly as it deserves

A great deal of what people buy a $300 watch for is not peer-reviewable. Offline maps on an unfamiliar trail either work or they do not, and you will know within a mile. A sapphire lens either scratches on a doorframe or it does not. A watch that states 21 days either reaches Sunday or it does not. Dual-band reception is hardware, and the claim that it is present is a specification rather than a performance promise.

Those are the Amazfit's wins, and they are real wins at a price where Garmin offers none of them. The cheapest Garmin we rank with a published multi-band row is a Forerunner, and it costs materially more than this Amazfit while publishing less stated endurance. If you are buying on published capability per dollar, the Balance 2 is the best number on this site, and we are not going to bury that because its evidence tier is weak.

The Garmin case, which is narrower than Garmin's marketing suggests

The vívoactive 6 is not the better watch on paper and we are not going to pretend otherwise. What it is, is the cheaper end of an ecosystem that keeps producing numbers other people can test, plus a documented path to the one sensor upgrade that measurably improves the data. It estimates VO2 max, runs PacePro, computes HRV status and Body Battery, and records running dynamics — and, as we go through on training status, it does notget Garmin's training status, acute load or training readiness layer. Garmin's own feature list names none of those three for this watch. If that analysis stack is why you want a Garmin, this is the wrong Garmin, and the Forerunner 570 comparison is the page that costs that decision out.

The verdict

Buy the Amazfit Balance 2 if you are buying published capability and you accept that nobody independent has checked the output. Dual-band GNSS, free offline maps, a sapphire lens, 10 ATM and a stated 33 dual-band GPS hours is a specification Garmin does not sell at this price, and for navigating, swimming and long days out it is the better instrument on the documents. Go in knowing the accuracy claim is unmethodized and that you are trusting the brand rather than a measurement.

Buy the Garmin vívoactive 6if a chest strap is part of your plan, or will be. That one capability — documented in Garmin's manual, absent from Amazfit's page — outweighs every spec-sheet row above it for anyone whose actual complaint is that their heart-rate data looks wrong during intervals. It is also the right answer if you want your data in an ecosystem that third parties keep testing, unflattering results and all.

Buy neitherif positioning accuracy is specifically the weakness you are upgrading away from. The Garmin cannot run a multi-band mode at all, and the Amazfit's dual-band reception has never been measured by anyone outside the company. The honest answer at that point is to spend past this price bracket — the running watch ranking has the watches with both the hardware and a published measurement record, and the GPS accuracy comparison has every figure anyone has actually measured.
