Amazfit GTR Mini 2 Review: A Slim Recovery Watch That Tracks More Than You’d Expect

The GTR Mini 2 makes sense if you want something much lighter than the Amazfit T-Rex for everyday wear. At 24.6 grams without the band, owners say they forget it is there. That matters for sleep tracking, bulky watches make side sleeping uncomfortable, and this one doesn’t.

The recovery-relevant data is solid. Owners who compare it with a chest strap report morning resting heart rate trends within a few BPM. The morning readiness score is the useful part for training: it gives you a simple nudge toward a hard day or an easy one.

Sleep tracking deserves special mention. Like every wrist tracker, its sleep stage numbers are estimates, so watch the trends rather than single nights. The sleep score gives you a quick at-a-glance number each morning without having to open the app.

Where it falls short versus the $300+ watches: no HRV-based recovery scores, no training load analysis, and the GPS is connected (uses your phone) rather than built-in. For a $90 watch, though, those are fair trade-offs.

Build quality gets good marks from owners. The aluminum case looks more expensive than it is, and skin irritation complaints are rare in the reviews.

The Balance 2 is the bigger step up. It has a 1.5 inch AMOLED screen under sapphire glass, up to 21 days of battery in typical use, 10 ATM water resistance, free offline maps and official HYROX training modes.

For recovery, it reads your sleep, heart rate variability and daily strain through the Zepp app, then rolls that into a single readiness style score so you know whether to push or back off. It is a better fit than the GTR Mini 2 if you train for hybrid events, lift seriously or want maps on your wrist.

If you would rather track recovery without a watch, see our Amazfit Helio Ring review, or the T-Rex 3 for something tougher.
