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 Pop 3R wears larger than the Samsung Galaxy Watch8 - Wi-Fi · 44mm (45.5mm vs 43.7mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch8 - Wi-Fi · 44mm is the slimmer of the two (8.6mm vs 10.8mm), so it slides under a cuff more easily.
On the wrist the Samsung Galaxy Watch8 - Wi-Fi · 44mm feels lighter (34g vs 55.48g, case only).
The Amazfit Pop 3R is thinner than 97% of the 46mm watches we track and the Samsung Galaxy Watch8 - Wi-Fi · 44mm than 99% of the 44mm ones — so both wear flatter than their widths suggest.
The Amazfit Pop 3R is 1.8mm wider, 0.5mm shorter, 2.2mm thicker and 21.5g heavier than the Samsung Galaxy Watch8 - Wi-Fi · 44mm. 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 45.5mm · Lug-to-lug 45.5mm · Thickness 10.8mm · 55g
Balanced Fit
45.5mm 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 45.5mm, 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.
