Smartwatch 2 ECG
Which one fits you
On wrists narrower than about 43mm, the Amazfit Smartwatch 2 ECG is the safer pick — it stays proportionate down to roughly 37mm, where the Amazfit Pop Pro starts to hang over the edge. Above 43mm both sit cleanly, and the Amazfit Pop Pro gives you more presence.
The Amazfit Pop Pro and Amazfit Smartwatch 2 ECG share a near-identical 35.5mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit Pop Pro is the slimmer of the two (11.4mm vs 13.7mm), so it slides under a cuff more easily.
On the wrist the Amazfit Pop Pro feels lighter (31g vs 49g, case only).
Among the 109 36mm watches we hold thickness for, the Amazfit Pop Pro is thicker than 76% — it will sit high even though the case width reads modest.
Among the 105 35mm watches we hold thickness for, the Amazfit Smartwatch 2 ECG is thicker than 96% — it will sit high even though the case width reads modest.
