Sinn EZM 3 Pre Owned with ETA 2824-2 Movement

Klarna payment not available on this item

Used Sinn EZM 3 originally purchased from us in 2016 and complete with box and papers. It has the ETA 2824-2 movement opposed to the newer models having the Seletta SW200 movement. It comes on the original Sinn rubber strap with is worn and an original Sinn brown leather strap which is very well worn, but the pin buckle can still be used on another strap. 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.
