Which one fits you
On wrists narrower than about 46mm, the Apple Watch Series 11 GPS Aluminium 42mm is the safer pick — it stays proportionate down to roughly 44mm, where the Amazfit Cheetah Square starts to hang over the edge. Above 46mm both sit cleanly, and the Amazfit Cheetah Square gives you more presence.
The Amazfit Cheetah Square wears larger than the Apple Watch Series 11 GPS Aluminium 42mm (38.7mm vs 36mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Apple Watch Series 11 GPS Aluminium 42mm feels lighter (30.3g vs 37g, 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.
The Apple Watch Series 11 GPS Aluminium 42mm is middle-of-the-pack for thickness among the 139 36mm watches in the database.
The Amazfit Cheetah Square is 2.7mm wider, 2mm longer, 0.2mm thicker and 6.7g heavier than the Apple Watch Series 11 GPS Aluminium 42mm. Both are rectangle.

Watch Fit Tool
For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Case 44.0mm · Lug-to-lug 44.0mm · Thickness 9.9mm · 37g
Balanced Fit
44mm on a 55mm wrist
Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 44mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
- 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.
