Which one fits you
On wrists narrower than about 48mm, the Samsung Galaxy Watch8 - Wi-Fi · 40mm is the safer pick — it stays proportionate down to roughly 45mm, where the Amazfit Balance starts to hang over the edge. Above 48mm both sit cleanly, and the Amazfit Balance gives you more presence.
The Amazfit Balance wears larger than the Samsung Galaxy Watch8 - Wi-Fi · 40mm (46mm vs 40.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch8 - Wi-Fi · 40mm is the slimmer of the two (8.6mm vs 10.6mm), so it slides under a cuff more easily.
On the wrist the Samsung Galaxy Watch8 - Wi-Fi · 40mm feels lighter (30g vs 35g, case only).
