Which one fits you

On wrists narrower than about 45mm, the Garmin Lily 2 Active is the safer pick — it stays proportionate down to roughly 40mm, where the Samsung Galaxy Watch8 - Wi-Fi · 40mm starts to hang over the edge. Above 45mm both sit cleanly, and the Samsung Galaxy Watch8 - Wi-Fi · 40mm gives you more presence.

The Samsung Galaxy Watch8 - Wi-Fi · 40mm wears larger than the Garmin Lily 2 Active (40.4mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Samsung Galaxy Watch8 - Wi-Fi · 40mm is the slimmer of the two (8.6mm vs 11mm), so it slides under a cuff more easily.

The Garmin Lily 2 Active is middle-of-the-pack for thickness among the 356 38mm watches in the database.

Among the 509 40mm watches we hold thickness for, the Samsung Galaxy Watch8 - Wi-Fi · 40mm is thinner than 83%, so it wears flatter than its width suggests.

Garmin Lily 2 Active vs Samsung Galaxy Watch8 - Wi-Fi · 40mm on a wrist

Put Garmin Lily 2 Active and Samsung Galaxy Watch8 - Wi-Fi · 40mm on the same arm, sized to your own wrist, and turn it. Side by side or stacked on one spot, whichever answers the question faster.

  • Garmin Lily 2 Active 38mm case, standing 11mm off the wrist.
  • Samsung Galaxy Watch8 - Wi-Fi · 40mm 40.4mm case, 42.7mm lug-to-lug, standing 8.6mm off the wrist.

Whether that clears your wrist edges is the question worth answering, and it depends on your wrist rather than on the case diameter.

Case shapes are generated from each watch's published measurements — case width, lug-to-lug and thickness — not from manufacturer 3D models, so the proportions are accurate while the dial is generic.
