The new permanent collection from watch microbrand royalty, Unimatic

Unimatic has made a name for itself as a microbrand full of surprises. Their sleek, minimalist approach to the classic dive watch captured our attention, and they've teased us with limited edition one-off designs for years. Well, no more. These four striking watches make up their brand-new permanent Unimatic Classic series. With the effortless look and precision detailing that they're known for, this collection is a planted flag for Unimatic—a demonstration to the world of what a performance timepiece can be. Masterfully made in Italy, the UC4 is a robust military watch with a fixed bezel, adding some toughness while maintaining a sharp silhouette.
