Which one fits you
On wrists narrower than about 50mm, the Watch X2 Mini is the safer pick — it stays proportionate down to roughly 45mm, where the Watch X3 starts to hang over the edge. Above 50mm both sit cleanly, and the Watch X3 gives you more presence.
The Watch X3 wears larger than the Watch X2 Mini (47.4mm vs 43.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Watch X2 Mini feels lighter (37.8g vs 43g, case only).
The Watch X2 Mini is thinner than 93% of the 43mm watches we track and the Watch X3 than 98% of the 47mm ones — so both wear flatter than their widths suggest.
The Watch X3 is 4.2mm wider, 4.2mm longer and 5.2g heavier than the Watch X2 Mini. 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
43.2mm 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 43.2mm, 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
47.4mm 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.
