Which one fits you

On wrists narrower than about 48mm, the Garmin Fenix 7S Pro Solar 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 Fenix 7S Pro Solar (45.5mm vs 42mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Amazfit Pop 3R is the slimmer of the two (10.8mm vs 14.1mm), so it slides under a cuff more easily.

On the wrist the Amazfit Pop 3R feels lighter (55.48g vs 63g, case only).

Among the 461 46mm watches we hold thickness for, the Amazfit Pop 3R is thinner than 97%, so it wears flatter than its width suggests.

Among the 661 42mm watches we hold thickness for, the Garmin Fenix 7S Pro Solar is thicker than 80% — it will sit high even though the case width reads modest.

The Amazfit Pop 3R is 3.5mm wider, 3.5mm longer, 3.3mm thinner and 7.5g lighter than the Garmin Fenix 7S Pro Solar. Both are circular.

For sports watches, Lug-to-Lug (L2L) is what matters most. Bulky is fine — overhang is not.
