Which one fits you
On wrists narrower than about 45mm, the Amazfit Bip U Pro is the safer pick — it stays proportionate down to roughly 43mm, where the Amazfit GTS 2e starts to hang over the edge. Above 45mm both sit cleanly, and the Amazfit GTS 2e gives you more presence.
The Amazfit Bip U Pro and Amazfit GTS 2e share a near-identical 35.5mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit GTS 2e is the slimmer of the two (9.9mm vs 11.4mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTS 2e feels lighter (25g vs 31g, case only).
Among the 109 36mm watches we hold thickness for, the Amazfit Bip U Pro is thicker than 76% — it will sit high even though the case width reads modest.
The Amazfit GTS 2e is middle-of-the-pack for thickness among the 140 36mm watches in the database.
