Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 51mm, the Watch Fit 4 Pro is the safer pick — it stays proportionate down to roughly 47mm, where the Watch D2 starts to hang over the edge. Above 51mm both sit cleanly, and the Watch D2 gives you more presence.
The Watch Fit 4 Pro wears larger than the Watch D2 (40mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch Fit 4 Pro is the slimmer of the two (9.3mm vs 13.3mm), so it slides under a cuff more easily.
On the wrist the Watch Fit 4 Pro feels lighter (30.4g vs 40g, case only).
Among the 356 38mm watches we hold thickness for, the Watch D2 is thicker than 90% — it will sit high even though the case width reads modest.
Among the 539 40mm watches we hold thickness for, the Watch Fit 4 Pro is thinner than 77%, so it wears flatter than its width suggests.
The Watch Fit 4 Pro is 2mm wider, 3.5mm shorter, 4mm thinner and 9.6g lighter than the 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.

Case 48.0mm · Lug-to-lug 48.0mm · Thickness 13.3mm · 40g
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.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 48mm.
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.

Balanced Fit
44.5mm 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 44.5mm, so you could go bigger.
