Which one fits you
On wrists narrower than about 51mm, the Watch 4 is the safer pick — it stays proportionate down to roughly 49mm, where the Watch Ultimate starts to hang over the edge. Above 51mm both sit cleanly, and the Watch Ultimate gives you more presence.
The Watch Ultimate wears larger than the Watch 4 (48.5mm vs 46.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch 4 is the slimmer of the two (10.9mm vs 13mm), so it slides under a cuff more easily.
On the wrist the Watch 4 feels lighter (48g vs 76g, case only).
The Watch 4 is thinner than 86% of the 46mm watches we track and the Watch Ultimate than 73% of the 49mm ones — so both wear flatter than their widths suggest.
The Watch Ultimate is 2.3mm wider, 2.3mm longer, 2.1mm thicker and 28g heavier than the Watch 4. 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.

Case 46.2mm · Lug-to-lug 46.2mm · Thickness 10.9mm · 48g
Balanced Fit
46.2mm 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 46.2mm, 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
48.5mm on a 55mm wrist
Across the wrist it works — 3.3mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
