Size, specs & wrist fit compared

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 GTR 4 Limited Edition wears larger than the Pop 3R (46mm vs 45.5mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the GTR 4 Limited Edition feels lighter (49g vs 55.48g, case only).
The GTR 4 Limited Edition is thinner than 84% of the 211 46mm watches we hold thickness for, the Pop 3R than 97% — so both wear flatter than their widths suggest.
The GTR 4 Limited Edition is 0.5mm wider, 0.5mm longer, 0.4mm thicker and 6.5g lighter than the Pop 3R. 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.
Amazfit GTR 4 Limited Edition
Case 46.0mm · Lug-to-lug 46.0mm · Thickness 11.2mm · 49g
Balanced Fit
46mm 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 46mm, 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.
