Instinct® E – 40 mm vs Venu 4 45mm
Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 47mm, the Instinct® E – 40 mm is the safer pick — it stays proportionate down to roughly 42mm, where the Venu 4 45mm starts to hang over the edge. Above 47mm both sit cleanly, and the Venu 4 45mm gives you more presence.
The Venu 4 45mm wears larger than the Instinct® E – 40 mm (45mm vs 40mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Venu 4 45mm is the slimmer of the two (12.5mm vs 13.6mm), so it slides under a cuff more easily.
On the wrist the Venu 4 45mm feels lighter (38g vs 41g, case only).
Among the 539 40mm watches we hold thickness for, the Instinct® E – 40 mm is thicker than 98% — it will sit high even though the case width reads modest.
Among the 385 45mm watches we hold thickness for, the Venu 4 45mm is thinner than 70%, so it wears flatter than its width suggests.
The Venu 4 45mm is 5mm wider, 5mm longer, 1.1mm thinner and 3g lighter than the Instinct® E – 40 mm. Both are circular.
