Which one fits you

On wrists narrower than about 51mm, the Watch 5 46mm is the safer pick — it stays proportionate down to roughly 49mm, where the Watch Ultimate 2 starts to hang over the edge. Above 51mm both sit cleanly, and the Watch Ultimate 2 gives you more presence.

The Watch Ultimate 2 wears larger than the Watch 5 46mm (48.5mm vs 46mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Watch 5 46mm is the slimmer of the two (11.3mm vs 12.9mm), so it slides under a cuff more easily.

On the wrist the Watch 5 46mm feels lighter (63g vs 80.5g, case only).

The Watch 5 46mm is thinner than 83% of the 46mm watches we track and the Watch Ultimate 2 than 75% of the 49mm ones — so both wear flatter than their widths suggest.

The Watch Ultimate 2 is 2.5mm wider, 1.8mm longer, 1.6mm thicker and 17.5g heavier than the Watch 5 46mm. 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.

Balanced Fit

46.7mm on a 55mm wrist

10:09TUE 12lug to lug 46.7mmyour wrist 55.0mm

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 46.7mm, so you could go bigger.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 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. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
