GTR 4 Limited Edition
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 4 Limited Edition wears larger than the Amazfit Bip 6 (46mm vs 40.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Amazfit Bip 6 is the slimmer of the two (10.45mm vs 11.2mm), so it slides under a cuff more easily.
On the wrist the Amazfit Bip 6 feels lighter (27.9g vs 49g, case only).
The Amazfit Bip 6 is middle-of-the-pack for thickness among the 530 40mm watches in the database.
Among the 211 46mm watches we hold thickness for, the Amazfit GTR 4 Limited Edition is thinner than 84%, so it wears flatter than its width suggests.
