FIELD: instrument making.
SUBSTANCE: universal timepiece comprises a first dial bearing geographical labels which correspond to different time zones and which define a circuit of 24 hours, second dial bearing a 24 hour circle which is concentric to first dial and configured for rotation. At second dial bearing time markings are arranged opposite geographical labels of first dial to indicate local time. Timepiece comprises manual means to shift selectively some of geographical labels by 1/24th of a revolution, to make it possible to change, by one hour, local times associated with geographical labels during a change from wintertime to summertime or from summertime to wintertime. Manual control means comprise a manual control member, configured to be activated from outside of timepiece and moving sectors clock face, which are located in first dial and are designed to control said control member for angular displacement by 1/24 turn relative to first dial. On movable sectors of dial there are geographic reference points, which correspond to items, in which there is transition to summertime. Said means include, on one side, multiple sprockets, rotating in first dial so that each of them is kinematically connected to one of moving sectors of dial, and on other opposite side programming disc configured to rotate with help of control member. On programming disc there are multiple pins, each of which can interact with one of sprockets to turn after bringing into rotation programming disc.
EFFECT: fast determination of time in different time zones at transition from winter to summer time and back.
