Which one fits you
On wrists narrower than about 54mm, the Amazfit Balance 2 is the safer pick — it stays proportionate down to roughly 50mm, where the Garmin Fenix 7X Pro Solar starts to hang over the edge. Above 54mm both sit cleanly, and the Garmin Fenix 7X Pro Solar gives you more presence.
The Garmin Fenix 7X Pro Solar wears larger than the Amazfit Balance 2 (51mm vs 47.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Balance 2 is the slimmer of the two (12.3mm vs 14.9mm), so it slides under a cuff more easily.
On the wrist the Amazfit Balance 2 feels lighter (43g vs 96g, case only).
Among the 83 47mm watches we hold thickness for, the Amazfit Balance 2 is thinner than 81%, so it wears flatter than its width suggests.
Among the 48 51mm watches we hold thickness for, the Garmin Fenix 7X Pro Solar is thinner than 90%, so it wears flatter than its width suggests.
