  • silicon nitride ceramic plate omega factories

    The base plate is ceramic, eliminating the need for jewelled bearings, since arbors can sit directly in the base plate, boosting the efficiency of the movement. Then the wheels of the gear train are made of silicon, which is both friction-free and also more rigid thanks to the redesigned tooth profiles.
