Display and fit
The GTR 3 Pro and GTR 3 have round screens, while the GTS 3 has a square screen. The Pro has the highest resolution, while the GTS 3 has the largest diagonal measurement. Wareable describes the GTS 3 as a 42.4 mm aluminum case weighing 24.4 g, making it the lightest of the three in its comparison.
Health tracking
All three share BioTracker 3.0 optical sensing for heart rate, stress, and blood oxygen, and support five satellite positioning systems, according to Wareable. Wareable identifies temperature sensing as a Pro-only feature, but cautions that it was not especially reliable in its experience. These are consumer watch measurements, not medical diagnoses.

Battery life: rated figures, not promises
Amazfit stated up to 21 days of typical-use battery life for the GTR 3 and up to 12 days for the GTR 3 Pro. Wareable lists up to 12 days for the GTS 3. Its comparison also lists up to 35 hours of GPS tracking for the GTR 3 and Pro and up to 20 hours for the GTS 3.
These figures are not directly comparable guarantees: actual runtime varies with settings and use. Wareable notes that always-on display, continuous monitoring, GPS, and sleep features can reduce endurance. The clearest paper advantage is the GTR 3’s longer stated typical-use maximum.
