Which one fits you
Both need much the same wrist — roughly 49–68mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Samsung Galaxy Watch8 LTE Classic wears larger than the Xiaomi Watch 2 (46.4mm vs 45.9mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch8 LTE Classic is the slimmer of the two (10.6mm vs 11.8mm), so it slides under a cuff more easily.
On the wrist the Xiaomi Watch 2 feels lighter (36.8g vs 63.5g, case only).
The Samsung Galaxy Watch8 LTE Classic is thinner than 97% of the 158 46mm watches we hold thickness for, the Xiaomi Watch 2 than 82% — so both wear flatter than their widths suggest.
The Samsung Galaxy Watch8 LTE Classic is 0.5mm wider, 1.1mm shorter, 1.2mm thinner and 26.7g heavier than the Xiaomi Watch 2. Both are circular.
