Instinct® E – 40 mm
Which one fits you
On wrists narrower than about 49mm, the Garmin Instinct® E – 40 mm is the safer pick — it stays proportionate down to roughly 42mm, where the Amazfit Active Edge starts to hang over the edge. Above 49mm both sit cleanly, and the Amazfit Active Edge gives you more presence.
The Amazfit Active Edge wears larger than the Garmin Instinct® E – 40 mm (46.6mm vs 40mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Active Edge is the slimmer of the two (12mm vs 13.6mm), so it slides under a cuff more easily.
On the wrist the Amazfit Active Edge feels lighter (34g vs 41g, case only).
Among the 117 47mm watches we hold thickness for, the Amazfit Active Edge is thinner than 68%, so it wears flatter than its width suggests.
Among the 540 40mm watches we hold thickness for, the Garmin Instinct® E – 40 mm is thicker than 98% — it will sit high even though the case width reads modest.
