We’ll certainly know the answer soon. More information at oris.ch. It has 21 jewels with a beat rate of 28,800, 4Hz. During tests undertaken by the Laboratoire Dubois, Calibre 400 deviated by less than 10 seconds a day after exposure to 2,250 gauss. The Oris caliber 400 is an automatic watch movement with a date. Using silicon for the anchor and escape wheel, along with non-ferrous material for the axes that hold the balance wheel, escape wheel and anchor, the impact of magnetic fields on Calibre 400 is reduced by more than 90% compared to standard Swiss mechanical movements. Magnetic fields have a direct effect on the hairspring causing the watch to gain or lose time or to come to a grinding halt. Fischli’s team devised a more reliable system based on a low-friction, slide-bearing system that only winds in one direction, which in turn is less complex and reduces wear and tear over the long run.Īnother directive for the new movement was to counter the magnetism we encounter in everyday life. Conventional rotors sit on a ball-bearing system and swing in both directions. Oriss professional divers watch, the AquisPro Date, is the latest watch to be equipped with Oriss in-house Calibre 400 movement. Oris also revisited the oscillating mass (or rotor) that generates the power for the mainsprings.
