FIELD: physics.
SUBSTANCE: secret clock comprises a housing consisting of a transparent front glass and a transparent rear glass which form a transparent region, and an opaque rim of the housing, a clock mechanism which comprises a mechanism for winding and moving arrows, a spring motor, a transmission mechanism, a main wheel system, a stroke with a governor, an arrow mechanism and a time indication means with coaxial hour and minute hands; the mechanism for winding and moving arrows, the motor and the transmission mechanism are located inside the opaque rim of the housing and are kinematically coupled with a transparent driving disc located in the transparent region; the main wheel system, the stroke with a governor and the arrow mechanism are located in the transparent region between the transparent front glass and the transparent rear glass, and the stroke with a governor is made in the structure of the tourbillon, which is arranged such that the axis of rotation of carriage of the tourbillon is coaxial with the axes of the hour and minute hands.
EFFECT: larger area of the transparent region, enabling the tourbillon and part of the units of the clock mechanism to be mounted in the transparent region, improved functional capabilities of the wheel system of the clock, smaller dimensions of the secret clock mechanism and larger space for the motor, while allowing installation of a more powerful motor in the clock and a longer operating range.
