Which one fits you
On wrists narrower than about 45mm, the Amazfit GTS 2 Mini is the safer pick — it stays proportionate down to roughly 43mm, where the Amazfit GTS 3 starts to hang over the edge. Above 45mm both sit cleanly, and the Amazfit GTS 3 gives you more presence.
The Amazfit GTS 2 Mini and Amazfit GTS 3 share a near-identical 35.8mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Amazfit GTS 2 Mini feels lighter (19.5g vs 24.4g, case only).
Among the 141 36mm watches we hold thickness for, the Amazfit GTS 2 Mini is thinner than 73%, so it wears flatter than its width suggests.
Among the 139 36mm watches we hold thickness for, the Amazfit GTS 3 is thinner than 96%, so it wears flatter than its width suggests.
