Which one fits you

On wrists narrower than about 44mm, the Lily 2 is the safer pick — it stays proportionate down to roughly 37mm, where the Fenix 7S Pro Solar Edition starts to hang over the edge. Above 44mm both sit cleanly, and the Fenix 7S Pro Solar Edition gives you more presence.

The Fenix 7S Pro Solar Edition wears larger than the Lily 2 (42mm vs 35.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Lily 2 is the slimmer of the two (10.1mm vs 14.1mm), so it slides under a cuff more easily.

On the wrist the Lily 2 feels lighter (24.4g vs 63g, case only).

Among the 655 42mm watches we hold thickness for, the Fenix 7S Pro Solar Edition is thicker than 81% — it will sit high even though the case width reads modest.

The Lily 2 is middle-of-the-pack for thickness among the 105 35mm watches in the database.

The Fenix 7S Pro Solar Edition is 6.6mm wider, 6.6mm longer, 4mm thicker and 38.6g heavier than the Lily 2. 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

42mm on a 55mm wrist

10:09TUE 12lug to lug 42.0mmyour wrist 55.0mm

Across the wrist it works — 6.5mm spare each side — but a tall watch on this wrist. Fine over a sleeve, awkward under one.

On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 42mm, 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.

Well inside your wrist on every measurement — you have room to go a size up if you want more presence.

On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 35.4mm, so you could go bigger.
