Amazfit
Active 2 vs Cheetah Square
Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 46–63mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Active 2 wears larger than the Cheetah Square (43.9mm vs 38.7mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Active 2 feels lighter (29.5g vs 37g, case only).
The Active 2 is thinner than 99% of the 44mm watches we track and the Cheetah Square than 74% of the 39mm ones — so both wear flatter than their widths suggest.
The Active 2 is 5.2mm wider, 0.1mm shorter and 7.5g lighter than the Cheetah Square.
