429 Too Many Requests

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.

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.

Everything was working with 27.0.1 on both my watch 11 and iPhone 17… for a while. Then recently Siri responses started getting unbearably slow, until today it said it “couldn’t set a timer on this device” because it couldn’t find the timers app. Power cycling and toggling Siri didn’t work for me. Unpairing and repairing the watch fixed both the timers and the sluggish responses. Took about 20 minutes and the only thing I really had to do to get set up again was verifying cards in Wallet.

I had same issue- I just fixed it by these steps: Toggle Siri off on iPhone. Wait a moment. Toggle it back on. Power off Apple watch and iPhone. Restart both Apple watch and iPhone and this fixed the problem for me. I can now tell Siri on Apple Watch to set a timer, as I used to.

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.

Thank you. Turning off Siri and turning it back on solved my problem. All working fine now.

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.

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

Did you try unpairing and re-pairing the watch? I have a Watch 12 and an iPhone 17 Pro, both with 27.0.1 versions. I Siri AI is turned on. I can set alarms and timers using Siri on my watch. One thing I do notice is that it takes a couple of beats longer than it did with "Siri Classic." It's just long enough that I start to think it doesn't work but then it does.

The WatchOS update to 27.0.1 along with the iOS update to 27.0.1 fixed the bug for me, too.

Disappointing. This is the most basic functionality.

Good luck.

If you're expecting Apple to magically fix your problem, I wouldn't hold your breath.

Reboot, restore, erase and set up as new are the 3 big steps in troubleshooting most technical problems. Odds are one of those will fix it. If not, contact Apple support.

watchOS 27.1 has not yet been released. Do you mean 27.0.1?

Restarting watch doesn’t help. Disabling and enabling Siri is a hassle for me. It deactivates everywhere: watch, phone, homepod.

Unpair and re-pair the watch. Or disable Siri AI and go back to Siri Classic.

i'm having the same issue with Siri beta, tried disabling, restarting both devices, then enabling siri, restarting devices, and the watch still won't set a timer or work with homekit.

"classic" siri works just fine immediately after toggling it on, no resets required.

So 2 weeks later, and suddenly I can no longer set timers on my watch using Siri. 😡 I tried the turn off Siri AI -> reboot watch and phone and the classic Siri could set a timer. After turning Siri AI back on, no joy. Further testing shows Siri AI can’t find a bunch of built-in apps with “open [timers | clock | calendar | sleep | mail]”. I didn’t test them all, but having to re-pair the watch every 2 weeks is a non-starter for me.

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.

Yes, it's easy and relatively quick to unpair and re-pair your watch. No, I don't care that you don't believe me and would rather argue than do any troubleshooting. I respect your right to make your own choices.

Best of luck.

Yeah, it very well could. Did you try reverting to a non beta version?

I have the same problem, and it can't set reminders for me either. All of the apps are on my watch and working fine, and Siri on every other device is also working. I tried turning Siri off and on again but that didn't work, and I'm not going to go through the hassle of resetting my Apple Watch because that probably won't work either. As for the official 'support' article, it hasn't been updated in years seemingly and has parts that are just not accurate anymore. The issue seems to be relatively widespread; there's a MacRumours thread about the issue which is already a few pages long.

KiltedTim reported that it did work. And it doesn't take very long or require that you do much other than wait for it to finish. It's certainly worth trying. Or, you can just continue to live with the problem.

You should let Apple know what you're seeing:

Product Feedback - Apple

MacRumours has a very apt name.

Yes, it is a hassle. It's not an instant process, and it takes a long time to get everything set up like it was before. I have done it before to fix a different issue and it was, to put it politely, a nightmare. Plus, it didn't even fix the issue I was having...

From what I've read it's worked for one person, and another one or two have said it hasn't worked. At best it's a 50/50 chance, and I'm not wasting a few hours for something that doesn't have a 100% chance of working.

And as for MacRumours, I assume the comment about the name is to try and say they're exaggerating or something like that. I don't know. But I've seen other people talk about it on Threads and Twitter, and there's obviously a lot more that I haven't come across. This is a real issue that a decent chunk of people are having!

Unpairing and re-pairing doesn't require any additional setup. It's reading everything from your most recent backup. If it's a "nightmare" you're doing something wrong.

Well, if people are saying that on Threads and Twitter then it must be true. My error.

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.

Ditto. Mine was working fine in ios 27, but since 27.1 the timers or even requesting a 10 minute indoor walk doesn’t work. If I finally get it to work, I’ll request a 5 minute countdown, and Siri spins for 30 seconds so I have to request a shorter countdown to offset the death spin. What the heck apple. I guess it’s back to normal Siri and Gemini.

I'm using Siri AI beta and watchOS 27.0.1. I have no problems setting timers with Siri.

In my case everything was working fine on 27 with Siri beta (although it was thinking sometimes too long) until 27.1

Well, about 20 minutes later the Stocks option reappeared. Weird. All is well again. Thanks again.

Yes, it sometimes takes a litle bit after a re-pair for everything to load again. When I restored my new Watch from my old watch backup, it awhile for some of my Infographic complications to show up again.

Glad you got it working.

Glad that fixed it — thanks for letting us know!

Worked me also. Thanks!!

Turning Siri off and back on did not fix mine. I am on the Siri beta if that makes a difference.

I have not. I am on the public release of iOS 27.0, but on the Siri “beta”.

Thank you. Timers are again setting quickly and I now see the expected Siri logo in action at the bottom of the Watch screen.

My bad. WatchOS 27.0.1 indeed.

Without pairing or doing whatever, it just fixed itself when I checked today.

Glad to hear that!

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.
