Electricity on Shabbat: Difference between revisions

# However, if it is still running some poskim hold that it is permitted to wind it on Shabbat, however, others hold it is forbidden.<ref>Yabia Omer 6:35 explains that it is permitted since the whole issue with winding the watch is that it is equal to fixing it but if it didn’t stop that isn’t considered fixing it to prevent it from stopping. Even though the Mishna Brurah 338:15 is strict unless there is a need for someone sick unless you can find a non-Jew. Piskei Teshuvot 338:9 cites the Daat Torah 338, Minchat Shabbat 80:240, and Darkei Chaim VShalom 419 as lenient. Teshuvot Vhanahagot 1:202 quotes that Rav Chaim Ozer was lenient. In his discussion, Yabia Omer has some interesting comparisons to discuss this halacha. He writes that it is comparable to the Nodeh Beyehuda YD 201:35 who says that you can put boards into the mikveh and that’s not a problem of having a mikveh formed with something that’s mekabel tumah since it didn’t start like that even if those boards are preventing the mikveh from becoming invalid. Similarly, the Trumat Hadeshen writes that you can preemptively fix the letters of a mezuzah so that they don’t fade too much and it isn’t considered an issue of not writing the mezuzah in order. Lastly, it is like the Eliya Rabba who says that you can soak meat that was out for three days since you’re keeping status quo and just preventing its status from becoming forbidden and that isn’t considered fixing (tikun).</ref>  

# Wearing a smartwatch or fitbit on Shabbat is forbidden.<ref>[http://www.zomet.org.il/?CategoryID=398&ArticleID=1050 Rabbi Rozen on zomet.org] explains that even if all the observable noises and notifications that the watch makes are turned off simply wearing it is forbidden since it isn't appropriate for Shabbat.</ref>
