Which one fits you
Both need much the same wrist — roughly 45–61mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Amazfit GTS 3 and Amazfit GTS 4 share a near-identical 36mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit GTS 3 is the slimmer of the two (8.8mm vs 9.9mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTS 3 feels lighter (24.4g vs 27g, case only).
Among the 139 36mm watches we hold thickness for, the Amazfit GTS 3 is thinner than 96%, so it wears flatter than its width suggests.
The Amazfit GTS 4 is middle-of-the-pack for thickness among the 139 36mm watches in the database.
