Which one fits you
Both need much the same wrist — roughly 48–67mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Garmin Fenix 7 Pro Solar wears larger than the Amazfit Pop 3R (47mm vs 45.5mm 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 14.5mm), so it slides under a cuff more easily.
On the wrist the Amazfit Pop 3R feels lighter (55.48g vs 79g, 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.
The Garmin Fenix 7 Pro Solar is middle-of-the-pack for thickness among the 98 47mm watches in the database.
The Garmin Fenix 7 Pro Solar is 1.5mm wider, 1.5mm longer, 3.7mm thicker and 23.5g heavier than the Amazfit Pop 3R. Both are circular.
