Instinct 3 Solar Tactical Edition 45mm
Which one fits you
Both need much the same wrist — roughly 47–65mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit Pop 3R wears larger than the Garmin Instinct 3 Solar Tactical Edition 45mm (45.5mm vs 45mm 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 14.9mm), so it slides under a cuff more easily.
On the wrist the Garmin Instinct 3 Solar Tactical Edition 45mm feels lighter (52g vs 55.48g, 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 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.
