Garmin
Descent™ Mk3i – 43 mm (010-02753-13)
Garmin
Lily 2 Active
The Garmin Descent™ Mk3i – 43 mm wears larger than the Garmin Lily 2 Active (43mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Garmin Lily 2 Active is the slimmer of the two (11mm vs 14.3mm), so it slides under a cuff more easily.
On the wrist the Garmin Lily 2 Active feels lighter (29g vs 49.3g, case only).
