Which one fits you
On wrists narrower than about 59mm, the Huawei Watch 5 42mm is the safer pick — it stays proportionate down to roughly 45mm, where the Noise Scout Kids starts to hang over the edge. Above 59mm both sit cleanly, and the Noise Scout Kids gives you more presence.
The Huawei Watch 5 42mm and Noise Scout Kids share a near-identical 42mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Huawei Watch 5 42mm is the slimmer of the two (10.5mm vs 12.8mm), so it slides under a cuff more easily.
On the wrist the Noise Scout Kids feels lighter (45g vs 51g, case only).
Among the 655 42mm watches we hold thickness for, the Huawei Watch 5 42mm is thinner than 89%, so it wears flatter than its width suggests.
The Noise Scout Kids is middle-of-the-pack for thickness among the 642 42mm watches in the database.
The Huawei Watch 5 42mm is 0.3mm wider, 13.2mm shorter, 2.3mm thinner and 6g heavier than the Noise Scout Kids.

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.

Case 42.0mm · Lug-to-lug 42.5mm · Thickness 10.5mm · 51g
Balanced Fit
42.5mm 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 42.5mm, 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.

Lugs Overhang
55.7mm on a 55mm wrist
The lugs run 0.4mm past each edge of your wrist — this is a size too big.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 55.7mm — look a size down.
Worn about 20mm further up your forearm it would clear — the arm is roughly 55.9mm across there.
