Carolus IX - Brown Calf

The calf leather has a rich, warm brown tone that catches the light beautifully, and the soft curves of the case wrap around my wrist better than any rectangular watch I’ve owned. It's quickly become my daily wear.

The tonneau shape is what sold me—it sits on the wrist with this soft, understated curve that feels more like a tailored accessory than just a watch. I've worn it daily for a month and the calf leather has already developed a subtle patina that looks even better than day one.

The brown calf leather has a beautiful patina right out of the box, and the cushioning on the inner strap makes it comfortable for all-day wear. Really pleased with how the tonneau shape sits on the wrist.
