Sinn EZM3 603.010

The diving watch EZM 3 is a mechanical watch made for the toughest diving jobs. This is because you can always rely on classical mechanics anywhere where a watch with a quartz movement could pose a risk due to electronic interference or failure of the internal power supply. This is especially true when these mechanics are protected by sophisticated Sinn technology.

Filling the case with a protective gas ensures optimum start conditions for our Ar-Dehumidifying Technology. The integrated drying capsule also absorbs the inevitable humidity which diffuses into the watch. The combination of carefully selected material dimensions and qualities together with perfect workmanship and complex sealing measures — such as double O-rings on the screwable crown — permits the approved use of the diving watch EZM 3 for a diving depth of 500 meters, corresponding to a pressure of 50 bar. This is an extreme performance value for which Magnetic Field Protection is crucial: an additional, solid soft iron sheath around the movement protects the accuracy of the watch up to magnetic field influences amounting to 100mT (=80,000 A/m).

All functions and printing on the dial not relevant to diving are muted in red.

History of Sinn Watches

Founded in 1961 by Helmut Sinn, a former World War II pilot and blind flight instructor, Sinn Watch Company quickly gained recognition for its aviation-inspired timepieces. Specializing in navigation clocks and pilot chronographs, Sinn's reputation for precision and durability was cemented during the 1980s and 1990s when their watches accompanied German astronauts on several space missions. These accomplishments demonstrated the brand's commitment to creating reliable timepieces capable of withstanding extreme conditions.

A new era began in 1994 when certified engineer Lothar Schmidt acquired the company, introducing significant technological advancements. Under Schmidt's leadership, Sinn pioneered innovations such as Ar-Dehumidifying Technology, DIAPAL lubrication-free escapements, and TEGIMENT hardened steel cases. Today, Sinn remains at the forefront of horological innovation, producing high-quality timepieces that blend traditional craftsmanship with cutting-edge technology. The brand's dedication to excellence and continuous improvement ensures its lasting legacy in the world of high-end watchmaking.
