Siri on Apple Watch cannot set timers or alarms after WatchOS 27 update

That isn’t expected behavior. Apple’s watchOS 27 guide still lists setting alarms and timers with Siri as supported. → Take action with Siri on Apple Watch - Apple Support

Since the Timer and Alarms apps work manually, I’d try resetting Siri rather than the Watch again. On the iPhone go to Settings > Siri (or Apple Intelligence & Siri) > Talk & Type to Siri, turn Siri off, then turn it back on. Restart both devices afterward. Apple specifically recommends that step when Siri isn’t working properly on Apple Watch. → If Siri isn't working on your Apple Watch - Apple Support

Also try the same “set a timer” request directly on the iPhone. If it works there but the Watch still says the Clock app isn’t installed, that points more toward a watchOS 27/Siri issue. I wouldn’t erase or unpair the Watch again at this point.

My watch Siri Timer commands were working just fine after I upgraded both to iOS 27. HOWEVER, after I enabled the Siri Beta, no joy.

I went into Settings | Siri on the phone and backed off to “regular” Siri from Siri AI (Beta), and watch Siri Timer commands are now working again.

I get that it’s a Beta, but doesn’t literally EVERYONE use voice commands on their watch to set timers?

Hope it gets fixed soon so I can have my cake and eat it too.

I reported this on Apple's feedback page. apple.com/feedback. I recommend everyone experiencing the setting a timer on Apple Watch using Siri to do the same.

Have you unpaired and re-paired your watch? That has resoved the issue for many people.

Also, make sure that both your watch and phone are updated to 27.0.1.

Same here. Can’t set a timer with Siri SI on my Apple Watch Ultra 2. Siri responds by saying it can’t set a timer because the clock app is not available on this device. I can only set a timer manually on the Apple Watch using the Timer App.

Numerous people have reported that unpairing and re-pairing the watch (a procedure that takes about 10 minutes, most of it hands-off) resolves the issue.

Came here because I was having the same issue. Consequently later that day, I received the watchOS 27.0.1 update, and that seems to resolved the issue for me. If you haven’t done that update yet, recommend trying that.

I was on Siri beta and I've had the problem with no timers or no alarms on Apple Watch.

I went and turned off Siri and then turned it back on and I changed back to Siri Classic vs. Siri Beta and the timer and alarms on watch now works again.

I don't know if it was Siri Beta or the turning Siri off and on that worked.

I really wanted to avoid that hassle and was just going to wait until the next watch OS update. But I decided to unpair/pair and that worked. Thanks. But now my Infographic watch face no longer allows me to add the Stocks complication. It has a checkmark saying it is OFF. Selecting that does nothing, thinking it would select it and turn it on. So I select another complication for that space (Top left) and that works. Then I go back to select Stocks and that option is totally gone. Frustrating.

Same problem for me on 12th gen Watch and iPhone 18 Pro. Setting timer using Siri beta on phone is no problem. Using Siri beta on Watch with 27.0.1 does not work. Changing back to Siri Classic and now setting timer on Watch with Siri works just fine.

I had the same problem with my Ultra 3. I ended up erasing the watch and setting it back up as new. Working normally now.

I've installed watchOS 27.0.1 and it fixed the issue for me.

Turning off, and leaving off, Siri beta is what did it for me. Didn’t need to do anything else.

I factory reset my watch to no avail. But, turning off the new Siri fixed my issues on both my watch and phone. Won’t be doing the new Siri.

While Siri sometimes worked on my Watch when I had Siri AI enabled, it was VERY slow and sometimes failed.

Being an impatient type, I disabled Siri AI and now when I Siri on my watch she responds quickly again.

Looking around the internet a bit more it seems that many people are having issues with Siri on the Watch if Siri AI is enabled.

Hope that Apple fixes this soon. I would like to enable Siri AI but not at the expense of most losing Siri on my watch.

I am also facing the same problem that after updating my watch, Apple Watch Series 10 GPS and iPhone 17 with iOS 27.0.1. I am not able to start the timer on my watch commanding Siri.

Have you tried unpairing and re-pairing the watch? Is the watchOS up-to-date?
