Which one fits you
On wrists narrower than about 48mm, the Fenix 7S Pro Sapphire Solar is the safer pick — it stays proportionate down to roughly 44mm, where the Venu X1 starts to hang over the edge. Above 48mm both sit cleanly, and the Venu X1 gives you more presence.
The Fenix 7S Pro Sapphire Solar wears larger than the Venu X1 (42mm vs 41mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Venu X1 is the slimmer of the two (7.9mm vs 14.1mm), so it slides under a cuff more easily.
On the wrist the Venu X1 feels lighter (34g vs 65g, case only).
Among the 661 42mm watches we hold thickness for, the Fenix 7S Pro Sapphire Solar is thicker than 80% — it will sit high even though the case width reads modest.
Among the 374 41mm watches we hold thickness for, the Venu X1 is thinner than 100%, so it wears flatter than its width suggests.
The Fenix 7S Pro Sapphire Solar is 1mm wider, 4mm shorter, 6.2mm thicker and 31g heavier than the Venu X1.
