Which one fits you
Both need much the same wrist — roughly 49–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Huawei Watch 4 and Samsung Galaxy Watch8 LTE Classic share a near-identical 46.2mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Huawei Watch 4 feels lighter (48g vs 63.5g, case only).
The Huawei Watch 4 is thinner than 86% of the 155 46mm watches we hold thickness for, the Samsung Galaxy Watch8 LTE Classic than 97% — so both wear flatter than their widths suggest.
The Samsung Galaxy Watch8 LTE Classic is 0.2mm wider, 0.2mm longer, 0.3mm thinner and 15.5g heavier than the Huawei Watch 4. Both are circular.
