Which one fits you

Both need much the same wrist — roughly 47–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.

The Venu 4 45mm wears larger than the Venu X1 (45mm vs 41mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Venu X1 is the slimmer of the two (7.9mm vs 12.5mm), so it slides under a cuff more easily.

On the wrist the Venu X1 feels lighter (34g vs 38g, case only).

The Venu 4 45mm is thinner than 70% of the 45mm watches we track and the Venu X1 than 100% of the 41mm ones — so both wear flatter than their widths suggest.

The Venu 4 45mm is 4mm wider, 1mm shorter, 4.6mm thicker and 4g heavier than the Venu X1.

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

45mm on a 55mm wrist

10:09TUE 12lug to lug 45.0mmyour 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 4753mm lug to lug. This one is 45mm, 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.
