Section: Questions Category: Halacha TAGS:make b'patish winding Halacha - kinetic watch | Submitted by ilan flax Answered by Rav Peretz Moncharsh | Question: | Answer: While a mechanical self-winding watch may be worn on Shabbos or Yom Tov as long as it has not stopped running, even though the spring will be tightened. However the same does not apply to a "kinetic" watch where the movement of the wrist generates electricity that recharges the watch's battery and may not be worn at all on Shabbos or Yom Tov.
