FIELD: watches and other time measuring instruments.;SUBSTANCE: invention relates to the field of watchmaking, to clock mechanisms with pointer indication of time, and more specifically to clock mechanisms of complicated type with indication opened under action of gravity depending on position of clock in space. Essence: the clock gravitational-rotary mechanism contains at least one shutter of indication closure, connected to it, at least one weight, as well as at least one spring, wherein at the vertical position of the gravitational-rotary mechanism, the gravity force acting on said at least one weight is greater than the spring resilience, which enables to displace said, at least one weight and the associated indication shutter to the required "closed"/"open" position, and in the horizontal position of the gravitational-rotary mechanism the gravity force acting on said at least one weight is less than force of elasticity of spring, which allows to move at least one weight and associated indicator shutter in position "open"/"closed". Clock with gravitation dependence of indication from position of clocks in space, comprising body, clock mechanism, dial with at least one aperture for display of additional indicator, arrows, additionally contain declared gravitational-rotational mechanism.;EFFECT: technical result is simplification of design of gravitational-rotational mechanism for on-demand display of additional indication located on the dial, high readability of the clock face, easy use of the sophisticated clock with multiple apertures for displaying the information, for example, displaying the date, day of the week, and the like; besides, with the help of the proposed mechanism it is possible to close the main indication or the minutes hand, or the clock hand, or both hands if it is necessary to indicate only the additional indication, for example, the lunar calendar or time indication in different time zones.;16 cl, 9 dwg
