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 Watch X3 wears larger than the Watch X (47.4mm vs 46.6mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch X3 is the slimmer of the two (11mm vs 12.1mm), so it slides under a cuff more easily.
On the wrist the Watch X3 feels lighter (43g vs 49g, case only).
The Watch X is middle-of-the-pack for thickness among the 121 47mm watches in the database.
Among the 85 47mm watches we hold thickness for, the Watch X3 is thinner than 98%, so it wears flatter than its width suggests.
The Watch X3 is 0.8mm wider, 0.4mm longer, 1.1mm thinner and 6g lighter than the Watch X. 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.
Oppo Watch X
Case 46.6mm · Lug-to-lug 47.0mm · Thickness 12.1mm · 49g
Sweet Spot
47mm on a 55mm wrist
47.0mm 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 47mm.
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.

47.4mm on a 55mm wrist
