Which one fits you
Both need much the same wrist — roughly 49–66mm 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 2 and Amazfit GTR 4 New share a near-identical 46.4mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit GTR 2 is the slimmer of the two (10.7mm vs 11.2mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTR 2 feels lighter (39g vs 49g, case only).
Among the 158 46mm watches we hold thickness for, the Amazfit GTR 2 is thinner than 93%, so it wears flatter than its width suggests.
Among the 149 47mm watches we hold thickness for, the Amazfit GTR 4 New is thinner than 77%, so it wears flatter than its width suggests.
