Which one fits you
On wrists narrower than about 50mm, the Google Pixel Watch 3 45mm is the safer pick — it stays proportionate down to roughly 47mm, where the Amazfit Balance 2 starts to hang over the edge. Above 50mm both sit cleanly, and the Amazfit Balance 2 gives you more presence.
The Amazfit Balance 2 wears larger than the Google Pixel Watch 3 45mm (47.4mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Google Pixel Watch 3 45mm feels lighter (37g vs 43g, case only).
The Amazfit Balance 2 is thinner than 81% of the 47mm watches we track and the Google Pixel Watch 3 45mm than 71% of the 45mm ones — so both wear flatter than their widths suggest.
The Amazfit Balance 2 is 2.4mm wider, 2.4mm longer and 6g heavier than the Google Pixel Watch 3 45mm. 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.

Sweet Spot
47.4mm on a 55mm wrist
Across the wrist it works — 3.8mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 47.4mm.
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.
