Which one fits you
On wrists narrower than about 47mm, the Epix Pro Gen 2 42mm is the safer pick — it stays proportionate down to roughly 44mm, where the Venu 3 starts to hang over the edge. Above 47mm both sit cleanly, and the Venu 3 gives you more presence.
The Venu 3 wears larger than the Epix Pro Gen 2 42mm (45mm vs 42mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Venu 3 is the slimmer of the two (12mm vs 14.1mm), so it slides under a cuff more easily.
On the wrist the Venu 3 feels lighter (47g vs 63g, case only).
Among the 661 42mm watches we hold thickness for, the Epix Pro Gen 2 42mm is thicker than 80% — it will sit high even though the case width reads modest.
Among the 386 45mm watches we hold thickness for, the Venu 3 is thinner than 76%, so it wears flatter than its width suggests.
The Venu 3 is 3mm wider, 3mm longer, 2.1mm thinner and 16g lighter than the Epix Pro Gen 2 42mm. Both are circular.
