Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 49–68mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit Balance 2 and Oppo Watch X2 share a near-identical 47.4mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Oppo Watch X2 is the slimmer of the two (11.8mm vs 12.3mm), so it slides under a cuff more easily.
On the wrist the Amazfit Balance 2 feels lighter (43g vs 49.7g, case only).
The Amazfit Balance 2 is thinner than 81% of the 47mm watches we track and the Oppo Watch X2 than 90% of the 48mm ones — so both wear flatter than their widths suggest.
The Oppo Watch X2 is 0.2mm wider, 0.8mm shorter, 0.5mm thinner and 6.7g heavier than the Amazfit Balance 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.

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.
