Which one fits you
Both need much the same wrist — roughly 49–67mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit Active Edge and Xiaomi Watch S3 eSIM share a near-identical 46.6mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Amazfit Active Edge feels lighter (34g vs 44g, case only).
The Amazfit Active Edge is thinner than 65% of the 110 47mm watches we hold thickness for, the Xiaomi Watch S3 eSIM than 74% — so both wear flatter than their widths suggest.
The Xiaomi Watch S3 eSIM is 0.4mm wider, 0.4mm longer and 10g heavier than the Amazfit Active Edge. Both are circular.
