FIELD: physics.
SUBSTANCE: body of the marking has a wall or casing, a cavity and a fixing device. The wall or casing is in form of a cavity boundary and has a cover with a peripheral element, a post with support members, and a bottom. The cover and the bottom are arranged opposite each other. The post with support members is placed between the bottom and the cover. The peripheral element is placed in the cavity and is able to interact with an area on the surface of the post. The support members are placed under the cover and are in form of outermost areas of supports and are placed opposite each other. The fixing device is formed by the support members and the cover with the peripheral element. The wall or casing is able to provide access into the cavity through the cover with the peripheral element, which is able to partially turn about the post. A head is formed by areas on the bottom, post, cover and one support member. A tail is formed by other oppositely lying areas on the bottom, post, cover and another support member. The peripheral element is placed in the head or tail.
EFFECT: reduced material consumption, simplification and unification of clock-face markings of wall clocks.
