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 GTR Mini and Samsung Galaxy Watch6 Classic - Wi-Fi · 43mm share a near-identical 42.8mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Amazfit GTR Mini is the slimmer of the two (9.25mm vs 10.9mm), so it slides under a cuff more easily.
On the wrist the Amazfit GTR Mini feels lighter (36.2g vs 52g, case only).
The Amazfit GTR Mini is thinner than 99% of the 315 43mm watches we hold thickness for, the Samsung Galaxy Watch6 Classic - Wi-Fi · 43mm than 84% — so both wear flatter than their widths suggest.
The Amazfit GTR Mini is 0.3mm wider, 0.3mm longer, 1.7mm thinner and 15.8g lighter than the Samsung Galaxy Watch6 Classic - Wi-Fi · 43mm. Both are circular.
