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 321 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.

Watch Fit Tool
For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Case 42.8mm · Lug-to-lug 42.8mm · Thickness 9.3mm · 36g
Balanced Fit
42.8mm on a 55mm wrist
Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 42.8mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
- 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.
