FIELD: physics.
SUBSTANCE: clock has a clock mechanism, an arrow mechanism, a clock face with an aperture with an indicator disc underneath. The aperture is surrounded by a movable indicator frame, the rotating mechanism of which includes at least one transmission mechanism interfaced with the wheel system of the clock mechanism, wherein the gear ratio of the wheels of the transmission mechanism is selected such that the angular velocity of the indicator frame is equal to or is a multiple of the angular velocity of the second pinion of the clock mechanism. The transmission mechanism is in the form of a first gear wheel and a second gear wheel, mounted on the same axis and engaged with the pinion of the second wheel.
EFFECT: larger useful space on the clock face, improved functional capabilities of the clock face, designing a reliable mechanism which provides continuous rotation of the movable indicator frame on the clock face with constant angular velocity which is equal to or is a multiple of the angular velocity of the second pinion of the second wheel of the clock mechanism.
