A clock device could be made using an idea close to the idea that the pendulum clock designers and creators had. If a pendulum having a bar and
along the circumference of the disc 18 are the permanent magnets 1thru 12 which move past the electrical magnet 14 with each rotation of the disc 16. Mounted on the central axle O of the disc 18 is the wheel 16 having 12 cuts along its circumference as the number of magnets on the disc 18. Engaged on the wheel and on an eccentrically located axle O1 on the support 13 are two pairs of gears 19, 20 and 21, 22 having a transmission ratio of I=19/20.21/22 as needed for the hand 17 to make one turn around the central axle for 30 or 20 minutes. The wheel 21 is mounted on 20 and 22 - on the hand 17 and freely on the axle O. A radial axle O3 is mounted on the back side of the disc 18 and a screw is provided in it for fastening the arch vane 23 ensuring rotation around the axle O3 when the screw is turned.
