Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 42mm, the Lily® 2 Classic is the safer pick — it stays proportionate down to roughly 37mm, where the Instinct® E – 40 mm starts to hang over the edge. Above 42mm both sit cleanly, and the Instinct® E – 40 mm gives you more presence.
The Instinct® E – 40 mm wears larger than the Lily® 2 Classic (40mm vs 35.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Lily® 2 Classic is the slimmer of the two (10.1mm vs 13.6mm), so it slides under a cuff more easily.
On the wrist the Lily® 2 Classic feels lighter (20.6g vs 41g, case only).
Among the 539 40mm watches we hold thickness for, the Instinct® E – 40 mm is thicker than 98% — it will sit high even though the case width reads modest.
The Lily® 2 Classic is middle-of-the-pack for thickness among the 105 35mm watches in the database.
The Instinct® E – 40 mm is 4.6mm wider, 4.6mm longer, 3.5mm thicker and 20.4g heavier than the Lily® 2 Classic. 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.
Lay your arm flat on a table, palm facing up
Measure across the flat top of your wrist (not the circumference)
Measure at the point where you wear your watch — typically just below the wrist bone
Wrist width ≠ circumference. We need the flat width across the top of your wrist where the watch sits, not how far around.

Balanced Fit
40mm on a 55mm wrist
Across the wrist it works — 7.5mm 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 40mm, so you could go bigger.
- 1. Lay your arm flat, palm up.
- 2. Measure the flat width across the top of your wrist — not the circumference.
- 3. Measure where you wear it, just below the wrist bone.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. The default: depth about seven tenths of the width. Typical figures, not this model’s own.

35.4mm on a 55mm wrist
Well inside your wrist on every measurement — you have room to go a size up if you want more presence.
