Which one fits you
Both need much the same wrist — roughly 48–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit GTR 3 Pro and Amazfit GTR 4 share a near-identical 46mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Amazfit GTR 3 Pro feels lighter (32g vs 34g, case only).
Among the 211 46mm watches we hold thickness for, the Amazfit GTR 3 Pro is thinner than 96%, so it wears flatter than its width suggests.
Among the 211 46mm watches we hold thickness for, the Amazfit GTR 4 is thinner than 98%, so it wears flatter than its width suggests.
