Which one fits you

On wrists narrower than about 45mm, the Amazfit Active is the safer pick — it stays proportionate down to roughly 38mm, where the Samsung Galaxy Watch6 Classic - LTE · 43mm starts to hang over the edge. Above 45mm both sit cleanly, and the Samsung Galaxy Watch6 Classic - LTE · 43mm gives you more presence.
