Which one fits you

On wrists narrower than about 45mm, the Lily 2 Active is the safer pick — it stays proportionate down to roughly 40mm, where the Forerunner 570 - 42mm starts to hang over the edge. Above 45mm both sit cleanly, and the Forerunner 570 - 42mm gives you more presence.

The Forerunner 570 - 42mm wears larger than the Lily 2 Active (42.4mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Lily 2 Active is the slimmer of the two (11mm vs 12.9mm), so it slides under a cuff more easily.

On the wrist the Lily 2 Active feels lighter (29g vs 42g, case only).

Both are middle-of-the-pack for thickness among the 42mm and 38mm watches in the database.

The Forerunner 570 - 42mm is 4.4mm wider, 4.4mm longer, 1.9mm thicker and 13g heavier than the Lily 2 Active. Both are circular.
