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 Samsung Galaxy Watch8 LTE Classic starts to hang over the edge. Above 49mm both sit cleanly, and the Samsung Galaxy Watch8 LTE Classic gives you more presence.
The Samsung Galaxy Watch8 LTE Classic wears larger than the Amazfit Cheetah Square (46.4mm vs 38.7mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Cheetah Square is the slimmer of the two (9.9mm vs 10.6mm), so it slides under a cuff more easily.
On the wrist the Amazfit Cheetah Square feels lighter (37g vs 63.5g, case only).
