Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 43mm, the Amazfit Active is the safer pick — it stays proportionate down to roughly 38mm, where the Garmin Venu 3S starts to hang over the edge. Above 43mm both sit cleanly, and the Garmin Venu 3S gives you more presence.
The Amazfit Active wears larger than the Garmin Venu 3S (42.36mm vs 41mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Active is the slimmer of the two (10.75mm vs 12mm), so it slides under a cuff more easily.
On the wrist the Amazfit Active feels lighter (27g vs 40g, case only).
Among the 723 42mm watches we hold thickness for, the Amazfit Active is thinner than 87%, so it wears flatter than its width suggests.
The Garmin Venu 3S is middle-of-the-pack for thickness among the 374 41mm watches in the database.
The Amazfit Active is 1.4mm wider, 5.1mm shorter, 1.3mm thinner and 13g lighter than the Garmin Venu 3S.
