Which one fits you
On wrists narrower than about 49mm, the Amazfit Cheetah Square is the safer pick — it stays proportionate down to roughly 46mm, where the Xiaomi Redmi Watch 3 Active starts to hang over the edge. Above 49mm both sit cleanly, and the Xiaomi Redmi Watch 3 Active gives you more presence.
The Amazfit Cheetah Square and Xiaomi Redmi Watch 3 Active share a near-identical 38.7mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit Cheetah Square is the slimmer of the two (9.9mm vs 10.9mm), so it slides under a cuff more easily.
On the wrist the Amazfit Cheetah Square feels lighter (37g vs 42g, case only).
Among the 339 39mm watches we hold thickness for, the Amazfit Cheetah Square is thinner than 74%, so it wears flatter than its width suggests.
