Which one fits you
On wrists narrower than about 51mm, the Apple Watch SE 3 GPS + Cellular 44mm is the safer pick — it stays proportionate down to roughly 46mm, where the Huawei Watch D2 starts to hang over the edge. Above 51mm both sit cleanly, and the Huawei Watch D2 gives you more presence.
The Apple Watch SE 3 GPS + Cellular 44mm and Huawei Watch D2 share a near-identical 38mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Apple Watch SE 3 GPS + Cellular 44mm is the slimmer of the two (10.7mm vs 13.3mm), so it slides under a cuff more easily.
On the wrist the Apple Watch SE 3 GPS + Cellular 44mm feels lighter (33g vs 40g, case only).
The Apple Watch SE 3 GPS + Cellular 44mm is middle-of-the-pack for thickness among the 356 38mm watches in the database.
Among the 356 38mm watches we hold thickness for, the Huawei Watch D2 is thicker than 90% — it will sit high even though the case width reads modest.
The Apple Watch SE 3 GPS + Cellular 44mm is 4mm shorter, 2.6mm thinner and 7g lighter than the Huawei Watch D2. Both are rectangle.

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
44mm 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 44mm, 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
48mm on a 55mm wrist
Across the wrist it works — 3.5mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
