FIELD: watches and other time measuring instruments.
SUBSTANCE: group of inventions relates to clock technology, in particular to a clock with a built-in calendar containing a clock mechanism, a calendar mechanism, a time indication means, a date indicating means. Technical result is achieved due to that calendar mechanism design corresponds to specified number of days of one of twelve (12) months of year, and date indication means provides indication of date of specified month. Clock can be used as part of a clock set containing, for example, 12 hours.
EFFECT: technical result is enabling simplification of design of clock mechanism with calendar with simultaneous reduction of its dimensions, as well as in creating a device which implements a new principle of operating a clock with a built-in calendar, which provides more reliable indication of the current date of the month, simplified use of clocks and a mechanism with such a calendar, increased durability thereof.
