Which one fits you
On wrists narrower than about 47mm, the Samsung Galaxy Watch8 - LTE · 40mm is the safer pick — it stays proportionate down to roughly 45mm, where the Huawei Watch Fit 4 Pro starts to hang over the edge. Above 47mm both sit cleanly, and the Huawei Watch Fit 4 Pro gives you more presence.
The Huawei Watch Fit 4 Pro and Samsung Galaxy Watch8 - LTE · 40mm share a near-identical 40mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Samsung Galaxy Watch8 - LTE · 40mm is the slimmer of the two (8.6mm vs 9.3mm), so it slides under a cuff more easily.
The Huawei Watch Fit 4 Pro is thinner than 77% of the 539 40mm watches we hold thickness for, the Samsung Galaxy Watch8 - LTE · 40mm than 82% — so both wear flatter than their widths suggest.
The Samsung Galaxy Watch8 - LTE · 40mm is 0.4mm wider, 1.8mm shorter, 0.7mm thinner and 0.4g lighter than the Huawei Watch Fit 4 Pro.
