Which one fits you
Both need much the same wrist — roughly 44–61mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit GTR Mini wears larger than the Garmin Fenix 7S Pro Solar (42.8mm vs 42mm 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 14.1mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTR Mini feels lighter (36.2g vs 63g, 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.
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 GTR Mini is 0.8mm wider, 0.8mm longer, 4.8mm thinner and 26.8g lighter than the Garmin Fenix 7S Pro Solar. Both are circular.
