Automatic watches on a three day Yom Tov
May one wear an automatic (kinetic) watch [which is currently working] over a three day Yom Tov?
Over a regular Shabbos, perhaps the watch has enough “power” to last over 24 hours without any movement, but in this case it is different…
What does Rav Weiss hold regarding this?
As long as the watch has not stopped working he may wear it on Shabbos. He has no intention to do anything to his watch which is running. The incidental charging my way of his movement is not considered melacha. In any event Kinetic watches generally have enough power to last for a few months once proprely charged.
