Model EZM 2 (case model 403) is a dive watch by Sinn, part of the Sinn EZM line from 1997 through 2005. It was replaced by the Sinn EZM 2B in 2006.


Sinn first introduced the Model 403 case as part of the Sinn EZM line in 1997. This would be EZM 2 and, like Sinn EZM 1, featured a left-side crown, rotating bezel, and large rugged case. The dial is black with white luminous markers and red accents. EZM 2 was produced until 2005. The original EZM 2 case measured 41 mm diameter.

In 2006, a civilian version, Sinn UX appeared and the EZM version was re-designated EZM 2B. This used a larger 44 mm case, though still used the model number 403.
