FIELD: physics.
SUBSTANCE: invention includes a helekim scale which has, on a circle, numbers, marks or divisions from 1 to 18 and a helekim display apparatus on the helekim scale, where the helekim display apparatus is in form a second hand which makes one revolution per minute, and the helekim scale is in form of a clock-face having numbers, marks or divisions from 1 to 18 on a circle. The regaim scale is also displayed. Apparatus for driving the regaim and helekim display apparatus are also described in the claims. The invention can also be used in devices for high-precision measurement of periodicity of moon phases and calendar devices which use the periodicity of moon phases in their scale, for scientific-informative purposes for understanding how ancient people related to time and time measurement, as well as for decorative purposes since the turning speed of the regaim hand is very high and is visually attractive for the viewer.
EFFECT: device for displaying Jewish time units which has a simple design, is accurate and reliable, and can be installed in virtually any analogue watch.
