Which one fits you

On wrists narrower than about 48mm, the Garmin Vivoactive 5 is the safer pick — it stays proportionate down to roughly 44mm, where the Amazfit Pop 3R starts to hang over the edge. Above 48mm both sit cleanly, and the Amazfit Pop 3R gives you more presence.

The Amazfit Pop 3R wears larger than the Garmin Vivoactive 5 (45.5mm vs 42.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

On the wrist the Garmin Vivoactive 5 feels lighter (36g vs 55.48g, case only).

The Amazfit Pop 3R is thinner than 97% of the 46mm watches we track and the Garmin Vivoactive 5 than 82% of the 42mm ones — so both wear flatter than their widths suggest.

The Amazfit Pop 3R is 3.3mm wider, 3.3mm longer, 0.3mm thinner and 19.5g heavier than the Garmin Vivoactive 5. Both are circular.
