Which one fits you
On wrists narrower than about 50mm, the Honor Watch GS 3i is the safer pick — it stays proportionate down to roughly 48mm, where the Xiaomi Watch 2 starts to hang over the edge. Above 50mm both sit cleanly, and the Xiaomi Watch 2 gives you more presence.
The Honor Watch GS 3i and Xiaomi Watch 2 share a near-identical 45.9mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Honor Watch GS 3i is the slimmer of the two (10.7mm vs 11.8mm), so it slides under a cuff more easily.
On the wrist the Xiaomi Watch 2 feels lighter (36.8g vs 44g, case only).
The Honor Watch GS 3i is thinner than 97% of the 203 46mm watches we hold thickness for, the Xiaomi Watch 2 than 82% — so both wear flatter than their widths suggest.
The Honor Watch GS 3i is 1.6mm shorter, 1.1mm thinner and 7.2g heavier than the Xiaomi Watch 2. Both are circular.

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.

Balanced Fit
45.9mm 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 45.9mm, 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.

Sweet Spot
47.5mm on a 55mm wrist
47.5mm across a wrist that has the room for it, and nothing else about the case argues with the size.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 47.5mm.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
