A new movement for wall clocks is described in this paper. Up to now, there is no clock which have the two following advantages together, silence and long battery life. At present, some clocks are very silent but the battery life ought to be limited to aprox. one year. On the other hand, clocks with long battery life are loud and even noisy for some people. This new movement solved those demerits by the use of new gear construction.
