FIELD: physics.
SUBSTANCE: clock with an analemma contains a body, a dial, a clockwork, an analog time indicator, a drive annual wheel, an analemma module containing a contour of the analematic "eight" and a sun pointer, while the analemma module additionally contains a radius cam and an angle cam kinematically connected with the drive wheel, while the angle cam drives the analemma disk wheel by means of the transfer mechanisms, and the radius cam transmits motion to the sun pointer by means of the transfer mechanisms so that, when the analemma disk rotates, the sun pointer moves strictly along the trajectory indicated by the contour of the analematic "eight".
EFFECT: simplifying the clock design with the analemma, reducing the overall clock dimensions with the analemma with simultaneous increasing the accuracy in displaying the true time on the clock and displaying the magnitude of the sun declination.
