人體動能手表裏面要不要電池？

Such kind of automatic watch, in fact, appeared in late 60s in the last century in HK. It ultizied the mechanical movement of the forearm to wind up a spring in the watch. The spring then drived a balance-wheel to run the watch. Electronic watch stil not appeared at that time.

I suppose modern automatic watch ultizies the mechanical movement of the forearm as a source of energy to charge up a condenser or battery to run the electronics of the watch.

人體動能手表裏面要不要電池？
→精工裝的是電容器。和電池功能相同。
你沒聽說過精工嘅kinetic手表嗎？
→有的。
如果要的話，電池要定期更換嗎？
→無論是充電電池或電容器，都是得更換的。(我換過許多次了，現在都自已改成一般電池。)

如果是自動上鋉的人體動能手錶不需要電池



沒聽說過精工嘅kinetic手表


如果真的有電池,當然一定要更換

不需要，但不是叫做人體動能，這是你自作嗎? 半個世紀以來都只是叫做自動手錶，英文是automatic 。
