Some Apple Watch Series 3 units restart on their own when they are near medical equipment

We are in the third generation of Apple Watch, but I confess that from the very first step there is a relatively annoying problem: it turns and moves, my watch restarts on its own, out of nowhere. It doesn’t seem to be a problem with my hardware itself, after all I had the original Apple Watch, the Series 2 and now the Series 3 (all with the same problem). Everything indicates, then, that this is a software problem, without any external interference – unless I have medical equipment here at home and didn’t know it.

Yes, because according to reports from some users, the new Apple watch (with or without cellular connectivity, it is good to note) is restarting alone when used within intensive care units (ICU) of some hospitals. The first thing that comes to mind, without a doubt, is a possible interference with specific medical equipment.

In one case, a user said he gave his wife an Apple Watch Series 3 Christmas, so that she could easily check messages even while working in the ICU. The problem is that the clock practically restarted every hour and, even changing the unit at Apple, the new clock continued to present the same problem.

In the Apple discussion forum there are several similar reports. The solution, apparently, is to put the watch in Airplane Mode, which is obviously not a good thing since you simply leave the device unusable like that.

It is worth noting that, in the Apple Watch manual, the company makes it clear that the watch can cause interference with medical devices. The reverse (medical equipment causing interference with the watch), however, is not mentioned in the product manual. Check it out:

Medical device interference. Apple Watch contains components and radios that emit electromagnetic fields. The Apple Watch, some of the bracelets, the Apple Watch Magnetic Charging Cable, the Apple Watch Magnetic Charging Case and the Apple Watch Magnetic Charging Dock contain magnets. These electromagnetic fields and magnets can interfere with pacemakers, defibrillators or other medical devices. Keep a safe distance between your medical device and the Apple Watch, your wristbands, the Apple Watch Magnetic Charging Cable, the Apple Watch Magnetic Charging Case and the Apple Watch Magnetic Charging Dock. Consult your doctor and the medical device manufacturer for information specific to your medical device. If you suspect that your Apple Watch, your wristbands, the Apple Watch Magnetic Charge Cable, the Apple Watch Magnetic Charge Case and the Apple Watch Magnetic Charge Dock are interfering with your pacemaker or other medical device, stop using them.

Interestingly, based on the reports, it appears that the problem affects only a few units of the Apple Watch Series 3. Who knows, all of this might also not be solved with a software update…
