Sinn Model U 200 (EZM 8) & Model U 200 SDR (EZM 8)

Diver’s 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. 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 (EZM 8) is a perfect addition to Sinn’s renowned collection of U 200 models. At the same time, this model fulfills the wish of many customers for a diver’s watch with a smaller diameter (37 mm) and lower weight—without compromising on functionality!

Germanischer Lloyd confirms and certifies the pressure resistance of model series U200 (EZM 8) to a diving depth of 2,000 meters as well as temperature resistance and function based EN 250 and EN 14143, the European standards for diving equipment.
