The Basics

Through fluid lines and organic shapes, Dietrich has managed to create a collection of so-called Organic Time Companions that are thoroughly futuristic in appearance. The dial is made up of four different layers, adding depth to the face of the watch. The leaf-like hands reflect the inspiration Dietrich found in nature. The unique design of the case makes for a very comfortable wear while being substantial in size. The movement is automatic and displays hours, minutes, seconds and an additional 24-hour wheel. The OT-3 has a stainless steel case with yellow accents.
