FIELD: horology.
SUBSTANCE: group of inventions relates to time devices containing an ultra-thin clock mechanism, which can be wound manually or automatically, and a drum for an ultra-thin clock mechanism. Drum for ultrathin watches comprises a drum housing with a gear rim, in the central part of which there is a drum shaft, the outer hook of which is connected to the inner end of the spring installed inside the drum housing, the outer end of the spring is fixed to the inner hook of the drum housing, wherein said drum additionally comprises unidirectional rotation mechanism arranged inside drum shaft. Ultrathin clock mechanism contains the above drum installed on the cover, which is a single support element for the set of kinematically connected wheels of the clock mechanism, the movement to which is transmitted from the drum by means of the toothed rim of its housing with teeth of the wheels or gears of the clock mechanism.
EFFECT: creation of a clock mechanism with a thin drum, by means of which it is possible to make an ultrathin clock, the maximum thickness of which is 1.5 mm in case of manual winding, increase of accuracy, simplification of a technological process of manufacturing.
