Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 45mm, the Garmin Venu 3S is the safer pick — it stays proportionate down to roughly 43mm, where the Amazfit GTR Mini starts to hang over the edge. Above 45mm both sit cleanly, and the Amazfit GTR Mini gives you more presence.
The Amazfit GTR Mini wears larger than the Garmin Venu 3S (42.8mm vs 41mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit GTR Mini is the slimmer of the two (9.25mm vs 12mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTR Mini feels lighter (36.2g vs 40g, case only).
Among the 315 43mm watches we hold thickness for, the Amazfit GTR Mini is thinner than 99%, 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 GTR Mini is 1.8mm wider, 1.8mm longer, 2.8mm thinner and 3.8g lighter than the Garmin Venu 3S. Both are circular.
