Which one fits you
On wrists narrower than about 48mm, the Garmin Bounce 2 is the safer pick — it stays proportionate down to roughly 45mm, where the Amazfit GTR 4 Limited Edition starts to hang over the edge. Above 48mm both sit cleanly, and the Amazfit GTR 4 Limited Edition gives you more presence.
The Amazfit GTR 4 Limited Edition wears larger than the Garmin Bounce 2 (46mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit GTR 4 Limited Edition is the slimmer of the two (11.2mm vs 12.4mm), so it slides under a cuff more easily.
On the wrist the Garmin Bounce 2 feels lighter (26.5g vs 49g, case only).
Among the 211 46mm watches we hold thickness for, the Amazfit GTR 4 Limited Edition is thinner than 84%, so it wears flatter than its width suggests.
Among the 312 43mm watches we hold thickness for, the Garmin Bounce 2 is thinner than 76%, so it wears flatter than its width suggests.
