FIELD: physics; clocks.
SUBSTANCE: invention relates to chronology, clock mechanisms with arrow indication of the current time and can be used in making and using unconventional secret wrist, table or pocket mechanical clocks. To simplify the design and improve usability, improve compactness of the device, improve visual appeal and mystique of clocks, while improving performance of indication means when transmitting motion in secret clocks, having a clock mechanism with a motor, a clock face formed by fixed and movable glasses and having a peripheral opaque region and a transparent region inside the opaque region, indication means located in the transparent region and moved by vibratory movements of the movable glasses, means of converting rotary movement of the motor of the clock mechanism into vibratory movement of the movable glasses and means of converting the vibratory movement of the movable glasses into the rotary movement of the indication means, according to the invention, the means of converting rotary movement of the motor of the clock mechanism into vibratory movement of the movable glasses are in the form of crank shafts mounted in the peripheral opaque region of the clock face, and the means of converting vibratory movement of the movable glasses into rotary movement of the indication means are in the form of crank shafts mounted in the transparent region of the clock face.
EFFECT: providing circular vibratory movements of movable glasses.
