　　全自动机械表不用电池，但要有发条的，和普通机械表**不同的是全自动机械表内没有人工上紧发条的手柄，而是在表内设置一个围绕发条齿轮的可转动的重锤，当人的手在运动的时候，重锤就做小幅度的圆周运动，带动发条齿轮，将发条上满，当发条紧到一定程度时，重锤仍在动，发条上满后齿轮空转，不再给发条上劲。

　　手表手动上弦为什么需要每天定时上满发条：手表运走能量靠的是发条的弹力提供的，当上满发条时，它的力矩较大，随着手表的运走，发条的发送，它的力矩也逐渐减小。手表从上紧发条到24小时这段时间，它的力矩输出是平稳的，此时走时也比较**，误差小。而超过24 小时以后，发条力矩会急骤下降，走失误差增大。为确保手表走时更准确，所以要每天定时上满发条。

　　柄头转多少圈可以满足手表走36小时以上：按照传动比推算，柄头转18 圈多一些，即可满足手表走时持续36小时。但是，由于每个人的上弦力度不一样，以及柄头内防水胶圈摩擦力的大小不同，因此，在发条完全放松时，柄头**旋转20圈以上。发条全部上紧，理论上可以延续走时40小时(特殊表款除外)，但是24小时后却不能保证手表走时精准度。

　　自动机械表怎么上发条：自动上弦手表其能量来源于佩戴者手臂的运动，故正常佩戴情况下(佩戴时间足8小时)不需手动上弦，只有因佩戴者运动量不足以给发条补充足够能量的时候，可采用手动上弦的方法来弥补，且上弦时表冠转动控制在二十圈以内。首次使用或超过40小时未曾佩戴过的自动上弦手表，应于再次佩戴时将表冠转动二十圈，以使发条初始上弦/再次启动机芯的驱动系统。

automatic mechanical watch battery, but to have the wound, and the only difference is the ordinary mechanical watch handle automatic mechanical watches no artificial wound, but set up a gear rotating around a hammer in the table, when the man's hand when in motion, heavy hammer on circular motion a small margin, driven by a spring gear, the spring is full of spring, when close to a certain extent, the hammer is still moving, idling gear full spring, not to wind up.

watch every time need manual winding wound up: the watch is on the wind energy. The elastic, when wound up, its torque is large, with a watch spring away, send its torque decreases gradually. Watch from the wound up to 24 hours during this period of time, its output torque is stable, the time is more accurate and less error. After more than 24 hours, a moment will drop sharply, lost error increases. In order to ensure that the watch is more accurate, it is time to wind up every day.

handle head to the number of laps can be more than 36 hours to meet the watch: in accordance with the transmission ratio of the calculation, the handle head to turn more than 18 laps, you can meet the watch to travel for 36 hours. However, due to the wind strength is not the same, and the handle head in waterproof apron friction of different sizes, therefore, in a completely relaxed, the handle head rotates about 20 times more than the best. The spring all tightened, theory can continue walking for 40 hours (special watch excepted), but after 24 hours, but can not guarantee the accuracy of the watch.

automatic winding automatic winding Watch: how the energy from the wearer's arm movement, so the normal wear condition (wear time for 8 hours) without manual winding, the wearer not only because of exercise for clockwork compensatory and enough energy, can be used to make up for the method of manual winding. And when the winding crown rotation control in the twenty circle. For the first time or more than 40 hours not wearing the automatic winding watches should be on again when wearing the crown is twenty turns, in order to make a initial winding drive system / start the movement again.
