- the mechanical timepiece provided with the posture detecting device of the present invention Even in such a posture, the swing angle of the balance with hair can be controlled extremely effectively. Therefore, the mechanical timepiece provided with the attitude detection device of the present invention can suppress the change in the instantaneous rate of the timepiece, and the conventional attitude detection device of the present invention shown by a square plot and a thick line in FIG. Compared to a mechanical watch that does not have a watch, the elapsed time from the entire volume with an instantaneous rate of about 0 to 5 seconds / day can be extended.
- the mechanical timepiece provided with the posture detecting device of the present invention has an instantaneous rate of about 32 hours or less, which is within about minus 5 seconds / day.
- the value of this duration is a duration in which the instantaneous rate in a conventional mechanical timepiece without the posture detecting device of the present invention is within about plus or minus 5 seconds / day, or about 1.45 of about 22 hours. It is twice.
- the attitude detection device of the present invention is small and highly accurate.
- the posture detecting device of the present invention has a simple structure and is suitable for realizing a mechanical timepiece with very high accuracy.
- attitude detecting device of the present invention is small and highly accurate, it can be used for machine tools, measuring machines, video equipment, recording equipment and the like.
