Apple Watch Ultra locking while on wrist

I have an Apple Watch Ultra running the latest release (9.1 build 20S75) and have had continuous issues with the watch locking itself. It has occurred while wearing multiple types of straps including the Ocean Band, Sport Loop, and the Alpine Loop. I wear my bands pretty tight (tight enough that they leave indentations on my wrist 360 degrees).


I've worn Apple Watches since 2016, and this only started happening with Watch OS 9 / Apple Watch Ultra.


Before the inevitable question, yes, I searched for similar posts and no, I didn't find any that had relevant answers.


Has anyone else been experiencing this issue with Watch OS 9 and/or Apple Watch Ultra? Any ideas on a fix? I'd prefer to avoid the un-pair / re-pair route, but will try it if it's a viable solution.


Thanks in advance.

I had the same problem with an Apple Watch 9 that I just bough. After I read all the support pages, tightened the strap, cleaned the sensors on the back, made sure the wrist sensor was on etc etc it still didn't solve the problem. The watch locked after 10 seconds while on my wrist.

The occurred to me the issue was not with the watch. The issue was with the iPhone (11) that the watch is synched to. I phones have different personalised modes of us - work / personal / driving / sleep. For some reason the iPhone was in sleep mode during the day and this was causing the Apple Watch to lock after 10 seconds as it would do during the night. On the locked phone check if you're on sleep mode. if so hold down the mode button at the bottom of the screen and select personal or work. I did this and immediately the Apple Watch was unlocked while on my wrist and the problem was solved. Hope this helps.

This is becoming a bit of a circular conversation. I've verified that wrist detection is enabled, but the watch randomly locks itself (as if it's not detecting my wrist).


The question was if others are having the same issue and if so what (if anything) has been done. I oversee iOS and Android developers, so I'm comfortable with the process of submitting bugs directly to Apple, but before I do that I wanted to see if others were 1) experiencing this as well, 2) if they have a fix. If 1 no, (which thus far seems like it) then I'll submit a bug ticket and move on.


Thanks.

It’s not because of the tattoos! I know a ton of people that are having the same problem that have zero tattoos. It’s always a different answer when you talk to someone at Apple. I’ve owned several watches from Apple, and never had this problem. You would think when they put out a new watch even if there is a problem they could figure it out. I had my watch for a week (bought it at the Apple Store) they told me I could replace it with a refurbished one. Yeah, like I want a refurbished watch to replace my brand new full price watch. Hopefully they can get this figured out and quit making up excuses!

If the watch is less than 14 days old and you bought it from Apple, you can return it for a refund and buy a new one. Don't go through the Genius Bar. Just bring back all of your packaging and your receipt and return it.

Nope. Not loose. It is snug. Not close enough to my hand that it would lock it. And I don't sleep with the watch. I have shifted it up a bit and that doesn't seem to help because it will slide down. Wearing it on the other hand... yea tried that, it is better but........ ridiculous that I can't wear the watch on my preferred arm because it keeps locking. I will say that the watch (series4 did it too) is causing marks on my wrist. Not a band issue. Directly below the watch. The detection eye is causing a "bruise" on my wrist. It goes away after a couple days, yet it should not be happening. That must have something to do with it. I showed it to my friend and she was surprised because I don't know how this could be happening.

My series 8 is doing the same thing. Mine will even lock when am scrolling through it. It locks when am wearing during a workout. It’s annoying. I have had Apple Watches since the first one, always wore the on the same wrist, on the same way but this is the first time I’ve had an issue.


I solved it by turning off the passcode 😂. But I need a resolution because I prefer it locked.

It’s not your tattoos. There is some sort of issue here as I bought a series 8 today. I took off my series 6 (which has been running perfectly). Put on the 8 and it’s been doing it to me since.

If the poster to whom you replied has tattoos, it could well be that that is the root cause of their problem. Tattoos are a known issue for this type of device (not just Apple's). That doesn't mean that it is the only possible cause.

Yes!! My ultra watch locks up every 10 seconds. Tech support with apple walked through every step still no resolution—- sent it off twice only to get “can not duplicate” —- although every time I get it back out it on my wrist it does same thing! Yes band is tight, wrist Detection is enabled —- completely frustrated and my watch is only 7 months old. Don’t understand why they won’t just replace my watch??

did you get it resolved ??
