Watch Fit Tool

For sports watches, Lug-to-Lug (L2L) is what matters most. Bulky is fine — overhang is not.

Which one fits you

Both need much the same wrist — roughly 48–65mm 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 and Amazfit Pop 3R share a near-identical 45.8mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

On the wrist the Amazfit GTR 3 feels lighter (32g vs 55.48g, case only).

Among the 212 46mm watches we hold thickness for, the Amazfit GTR 3 is thinner than 93%, so it wears flatter than its width suggests.

Among the 461 46mm watches we hold thickness for, the Amazfit Pop 3R is thinner than 97%, so it wears flatter than its width suggests.
