It was revealed in the previous paper that the performances of IF gears are superior to those of several kinds of conventional watch gears.
Thereupon it has been tried to apply IF gears to a watch, and the variation rate of torque ratio of both IF gears and the conventional watch gears which were designed for the same watch under the same conditions has been measured.
The results are as follows.
1) The variation rate of torque ratio of IF gears is about 40% less than that of the conventional watch gears.
2) The uniformity of the variation rate of IF gears is better than that of the conventional watch gears.
