Which one fits you

On wrists narrower than about 46mm, the Active is the safer pick — it stays proportionate down to roughly 38mm, where the Cheetah Square starts to hang over the edge. Above 46mm both sit cleanly, and the Cheetah Square gives you more presence.

The Active wears larger than the Cheetah Square (42.36mm 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 10.75mm), so it slides under a cuff more easily.

On the wrist the Active feels lighter (27g vs 37g, case only).

The Active is thinner than 87% of the 42mm watches we track and the Cheetah Square than 74% of the 39mm ones — so both wear flatter than their widths suggest.

The Active is 3.7mm wider, 8.1mm shorter, 0.8mm thicker and 10g lighter than the Cheetah Square. Both are rectangle.

For sports watches, Lug-to-Lug (L2L) is what matters most. Bulky is fine — overhang is not.
