Vladas jel svaki Etin mehanizam podleže DIN 8309 or ISO 764 standardima? Šta je u stvari modifikacija mehanizma?
ORIS watches are anti-magnetic in accordance with the definitions of the DIN 8309 or ISO 764 standards. These standards are based on the accidental exposure of a watch to a homogeneous magnetic field of 4,800A/m. As part of the test, the watch is placed in a magnetic field along three different axes, for one minute each time. In order to pass the test, a mechanical watch should not stop within the three periods indicated above. Further, the effect of the residual magnetism should not exceed 30 seconds per day for a gent’s watch and 45 seconds per day for a lady's watch. In today's world we are continuously exposed to electromagnetic fields of differing strengths. The metal case of an ORIS watch functions like a cage and protects the movement against magnetic fields as specified above. Nevertheless, the movement can be magnetized unintentionally. If this happens, it will inevitably be less accurate and the rate will be irregular. If this does happen, your official ORIS Customer Service has a machine that will demagnetize a mechanical watch quickly and easily.
