Which one fits you
Both need much the same wrist — roughly 43–58mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit Bip U and Amazfit Bip U Pro share a near-identical 35.5mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
Among the 109 36mm watches we hold thickness for, the Amazfit Bip U is thicker than 76% — it will sit high even though the case width reads modest.
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.
