Diving watches must meet the highest requirements in terms of reliability and robustness. So it’s no wonder they place high demands on design, construction and material. That’s why many divers rely on Sinn watches. And they also appreciate the many benefits provided by the U200 (EZM 8). For example, connoisseurs swear by the seawater-resistant case made of German submarine steel, the captive bezel hardened with TEGIMENT Technology and the patented Ar-dehumidifying technology that provides enhanced freedom from fogging. With characteristics like these, the U200 is a perfect addition to our renowned collection of U models. At the same time, this model fulfills the wish of many customers for a diving watch with a smaller diameter (37 mm) and lower weight – without compromising on functionality!
