Instinct 3 Solar Tactical Edition 45mm
Which one fits you
Both need much the same wrist — roughly 47–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit Balance wears larger than the Garmin Instinct 3 Solar Tactical Edition 45mm (46mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Balance is the slimmer of the two (10.6mm vs 14.9mm), so it slides under a cuff more easily.
On the wrist the Amazfit Balance feels lighter (35g vs 52g, case only).
Among the 211 46mm watches we hold thickness for, the Amazfit Balance is thinner than 98%, so it wears flatter than its width suggests.
Among the 386 45mm watches we hold thickness for, the Garmin Instinct 3 Solar Tactical Edition 45mm is thicker than 83% — it will sit high even though the case width reads modest.
