Since the update to watchOS 10.0.1 and iOS 17.0.2, the calendar on my Apple Watch doesn't sync anymore.
It displays the old appointments, from before the updates. The new and changed items are simply not shown.

No, not on the Apple Watch itself. But on your iPhone; the Apple Watch app on your phone, which controls your Apple Watch.
You will see in the app, in the list of installed/enabled apps, the Calendar slide will be set to ‘enable’.
Just slide it to disable. The Calendar app will be uninstalled from the Apple Watch.
After that just re-enable and the Calendar will re-appear on your watch.
Hello Captain-_-Chaos,
Your Apple Watch should show you events from the past six weeks and (in some views) for the next two years. If it isn't syncing the new events or changes you make in Calendar on your iPhone, there are a few troubleshooting steps we can try to refresh that connection.
If you're still not seeing those new or updated events, please contact Apple Support for more advanced support options. You can connect from the Get Support portal in most countries.
Cheers!
Thank you for your suggestions. I haven’t been able to put them to the test.
I solved the problem myself by uninstalling the Calendar app in the Apple Watch menu on my iPhone and re-installing the app. Everything worked perfectly after that.
Hi, can you tell me how you uninstalled the calendar app on your Apple Watch? Is the built in calendar app or a separate app you purchased? Thanks.
It is the built-in calendar app.
but the issue was already solved.
as you can read above.
If I understood correctly it was solved by uninstalling the calendar app so my question was how to uninstall the calendar app so I can fix the same issue. I don’t get the option to uninstall the calendar app. I’m not sure what you meant by “the Apple Watch menu” on your iPhone. Is that menu on settings? On the Watch app? I’m also using WatchOS 10 and iOS 17 as well. Thank you.

Hiya,
in agreement with you - been struggling to follow the advice on how to remove or disable a built-in app on an Apple Watch! Found this online just now and tried it but it is not possible to delete the Calendar app from the Apple Watch following these instructions! Grrrrr.....

Open the Apple Watch app on your iPhone. Scroll to installed apps. De-select Calendar (slide to disable).
Restart the Apple Watch.
the calendar app will disappear from your Apple Watch.
After that, just return to the Apple Watch app on your iPhone and slide the Calendar selection button to enable. Restart your Apple Watch. The calendar app will be reinstalled on your Apple Watch.
With all due respect, I have tried to do exactly as you describe - a number of times - except that I do not have the options you have to make it work. I appreciate your efforts to be helpful and am grateful that someone is trying to share what worked for them.
Where things do not seem to be the same is that your menu options sound very different to mine and I suspect for the other person who has also asked some questions seeking clarity on how you managed to get this to work when neither of us can.
Incidentally, I have done some investigating and it does appear that the calendar app cannot be removed the way you are describing? Bringing me back to the point - you seem to have different options on your operating system.
Thanks again for taking the time to share your advice and to repeat it. There really is no need to reply unless you can see why there is a difference between your operating system and mine: given we are both stating we are using the most up to date versions.
You’re right. I’ve checked and the option I described above isn’t available.
Turns out: I did all that with the app ‘WeekCal’ … assuming that was the calendar app.
I’m so sorry for the mis-understanding. I feel really stupid now 🫢
Haha - no worries! Thanks so much for getting back and clarifying.
The potential good news is that you have a Calendar app and by doing what you described above it then started to work with updating between phone and apple watch?!
Will give it a try on the Weekcal app and see how I get on. Thanks again!
you guys keep saying „uninstall Calendar” but HOW?? OS 8.8.1 does not give such an option
Tried everything and Apple Calendar will still not sync. Thanks anyways.
After trying everything here, this worked. Also pressing the button gives you no feedback, but the sync happened on my watch about 10 seconds later.

I was having the exact same issue: calendar changes made on my computer were not syncing to my watch. I discovered that the calendar app on the Apple Watch syncs only with the iPhone. So after making calendar changes on a Mac, I needed to open the calendar app on my phone and allow the changes to sync there. Once I did, the changes appeared on my watch was well.
Not sure if the same applies to everyone, but hopefully that's helpful to a few folks.
