Cheetah Square vs Pop 3R
Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 48mm, the Cheetah Square is the safer pick — it stays proportionate down to roughly 46mm, where the Pop 3R starts to hang over the edge. Above 48mm both sit cleanly, and the Pop 3R gives you more presence.
The Pop 3R wears larger than the Cheetah Square (45.5mm vs 38.7mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Cheetah Square is the slimmer of the two (9.9mm vs 10.8mm), so it slides under a cuff more easily.
On the wrist the Cheetah Square feels lighter (37g vs 55.48g, case only).
The Cheetah Square is thinner than 74% of the 39mm watches we track and the Pop 3R than 97% of the 46mm ones — so both wear flatter than their widths suggest.
The Pop 3R is 6.8mm wider, 1.5mm longer, 0.9mm thicker and 18.5g heavier than the Cheetah Square.
