Which one fits you
On wrists narrower than about 49mm, the Google Pixel Watch 4 - 45mm is the safer pick — it stays proportionate down to roughly 47mm, 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 Google Pixel Watch 4 - 45mm (46.6mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Amazfit Active Edge feels lighter (34g vs 36.7g, case only).
The Amazfit Active Edge is thinner than 65% of the 47mm watches we track and the Google Pixel Watch 4 - 45mm than 70% of the 45mm ones — so both wear flatter than their widths suggest.
The Amazfit Active Edge is 1.6mm wider, 1.6mm longer, 0.3mm thinner and 2.7g lighter than the Google Pixel Watch 4 - 45mm. Both are circular.
