Which one fits you
On wrists narrower than about 48mm, the Amazfit Active 2 is the safer pick — it stays proportionate down to roughly 46mm, where the Samsung Galaxy Watch8 - Wi-Fi · 44mm starts to hang over the edge. Above 48mm both sit cleanly, and the Samsung Galaxy Watch8 - Wi-Fi · 44mm gives you more presence.
The Amazfit Active 2 and Samsung Galaxy Watch8 - Wi-Fi · 44mm share a near-identical 43.9mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Samsung Galaxy Watch8 - Wi-Fi · 44mm is the slimmer of the two (8.6mm vs 9.9mm), so it slides under a cuff more easily.
On the wrist the Amazfit Active 2 feels lighter (29.5g vs 34g, case only).
The Amazfit Active 2 is thinner than 99% of the 316 44mm watches we hold thickness for, the Samsung Galaxy Watch8 - Wi-Fi · 44mm than 99% — so both wear flatter than their widths suggest.
The Amazfit Active 2 is 0.2mm wider, 2.1mm shorter, 1.3mm thicker and 4.5g lighter 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.

Balanced Fit
43.9mm 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 43.9mm, 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.
