Garmin Venu 3 Review - Lightweight Comfort, Stylish Design

The moment I first put on the Garmin Venu 3, I was impressed by its refined look and premium feel. The round dial with narrower bezels creates a more immersive visual experience, and the 1.4-inch AMOLED display is bright, colorful, and easy to read - even under direct sunlight. Unlike rugged sports watches, the Venu 3 has a sleek design that blends well with everyday outfits.

What stood out to me was the quality of materials. The Corning Gorilla Glass 3 and brushed metal bezel give it a solid, durable feel that resists scratches from daily wear. The lightweight build makes it easy to wear all day - whether I’m running, cycling, or sleeping. The soft silicone strap feels gentle on the skin, stays breathable even when sweating, and is ideal for extended use.

With my smaller wrist, I tried both the Venu 3 and Venu 3S models. I preferred the 3S - its 41mm case fit more snugly and felt more balanced, especially for those with slimmer wrists or a preference for a compact design. The hidden button layout on the right side also gives the watch a cleaner, more streamlined appearance. You can check our article of Garmin venu 3 vs 3s.
