Which one fits you
On wrists narrower than about 44mm, the Amazfit Pop 3S is the safer pick — it stays proportionate down to roughly 13mm, where the Amazfit Bip S starts to hang over the edge. Above 44mm both sit cleanly, and the Amazfit Bip S gives you more presence.
The Amazfit Bip S wears larger than the Amazfit Pop 3S (35.3mm vs 11mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Amazfit Bip S feels lighter (31g vs 57g, case only).
Among the 128 35mm watches we hold thickness for, the Amazfit Bip S is thicker than 80% — it will sit high even though the case width reads modest.
