Can my Apple Watch detect a fall if it's in my pocket or on a lanyard around my neck?

If you want the Apple Watch to perform to specification and as marketed, it needs to be worn on your wrist. Please review the information in the Apple Support article I’ve linked to below. Please note, even wearing the watch incorrectly on your wrist can affect the performance of a wrist watch.

I strongly suspect Jeff Donald is correct but if this is a health issue, you may want to contact Apple support to be sure.

But again, if it is a serious health issue, please talk to your doctor. If it's too uncomfortable to wear the watch, they may recommend a non-Apple device that can be worn off the wrist. Your health and safety must come first.

I think Carol B. may be on the right track. There are purpose-built devices that can be warn on a lanyard. As their only purpose is to detect falls, they may work better for you.

I'm sure you're right, Idris. Guess I'll have to suck this up and find another device.

Thanks, All!

As Carol B. said, your health and safety is the important thing here.

Best of luck!
