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 Huawei Watch GT 6 - 46mm 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 Huawei Watch GT 6 - 46mm is the slimmer of the two (11mm vs 14.9mm), so it slides under a cuff more easily.
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.
Among the 211 46mm watches we hold thickness for, the Huawei Watch GT 6 - 46mm is thinner than 88%, so it wears flatter than its width suggests.
The Huawei Watch GT 6 - 46mm is 1mm wider, 1mm longer, 3.9mm thinner and 0.7g lighter than the Garmin Instinct 3 Solar Tactical Edition 45mm. Both are circular.
