Santos Mods

Santos mods bring an angular case to your wrist. Light and dark dials and different metal colours give this collection a variety of expressions.

1 variant · Free shipping within Germany

How to choose your Santos mod

An angular case can feel different from a round watch of similar diameter. Compare the product photos and dimensions with a watch that already fits you well. We can help you personally with questions about fit.

Our product pages show each variant with its own photos and specifications. Standard models are delivered within Germany within 5 working days of receipt of payment.
