Calendar Not Syncing

I'm experiencing incorrect syncing with Facebook events. I have the Facebook calendar (or whatever it's called) turned off everywhere (phone, Mac, iPad), yet a few days ago I started seeing Facebook events as a complication on the watch face. If I looked at the calendar app on the watch, sometimes the Facebook event was there and sometimes it wasn't. It never appeared on the phone. Very confusing.

Restarting the phone and watch didn't fix it. Resetting the sync data (via the iPhone watch app) seems to have worked, but judging by others' experiences, I don't expect it to stick.

Running watch OS 2.0 and iOS 9.0.2 on an iPhone 5S.

I really wish I could delete the Facebook calendars entirely, but that seems to be impossible.

I've done exactly what you have done with exactly the same results. Selecting the icon My Watch on iPhone5s, then General, scrolling to bottom select Reset, then selecting last item of three "Reset Sync Data". Holding selection down generates a grey background on the selection. Releaseing the "Reset Sync Data", selections returns to its orange font and but nothing happens. Watch still not updated. Frustration!!!! Appreciate your post, now if Apple would issue an update, but that's too easy.

I went in to the Apple Store for "Genius Bar" assistance after exhausting all options that I could do on my own. They performed diagnostics but were unable to identify any issues apart from the lack of syncing. They didn't recognize this as a "known problem" even though I repeatedly said that there were multiple support threads on the topic. They have taken my watch and sent it to be diagnosed and repaired by the central service center. They were unable to revert the OS in the Apple Store. I will update once I get a response...it continues to be in "Diagnosing Product" status....

Don't know if this is a pereament fix, but on the iWatch went to SETTINGS, GENERAL, and RESET. That Reset removed all data from the watch. Had to setup watch again with Restore selection after all data was removed. Calendar is now working.

I tried the same method: Settings-Reset-Restore but the problem is stil there! Calendar NOT syncing!

Sorry that didn't work for you. For me, it did take about an hour for the iWatch to fully get its Calendar back.

This is ridiculous. Everything on exchange worked perfectly yesterday. Today, suddenly none of my exchange appointments are syncing. I only have one exchange calendar and it is the only calendar that syncs with my Apple Watch. Why are apple products becoming increasingly buggy? Is it just me or does it seem like major features are becoming major weaknesses in apple product releases! Oh and I've reset, repaired, reenabled everything that forum members recommended to no avail.

I Agree very frustrating. Oh and don't waste your money if you read the Forum advice to purchase Fantastical as a fix. I spend the dollars only to find the product is impacted in the same way as Apple calendar

Having the same problem with one work (MS Exchange) account and one Google Account with multiple calendars.

After reading most replies I tried deleting ALL my Other Calendars from Google (in the Calendar Settings) - This included Country Holidays, etc, and it immediately fixed the problem and the watch synced with the iPhone (showing both my Exchange calendar and any Google Calendars I own and have visible in my iPhone).

I have been having the same problems with syncing for about a week. I have tried most of the suggestions outlined in this chain of messages without success. This is one of my favorite features of the Apple Watch.

I eventually relented and reset the watch and paired it as a new device. It ***** because I lost a lot of settings and setup work that is done but solved the problem when no amount of calendar fiddling seemed to work. All I care about is that it's back on my watch and I hope it stays that way until Apple can get it fixed in the next update. :-/

I just received a notification from Apple, indicating that OS 2.01 for Apple Watch is available for download. The notification notes that the update fixes Calendar syncing issues. Has anyone downloaded the update? Is the problem fixed?

Thanks for letting us know about the update. I'm downloading it now. Unfortunately I moved jobs and don't have an MDM on my phone anymore so I have no way to test the fix. However I strongly suspect this update does address the problem since the release notes specifically mentioned fixing problems syncing calendar events from a MANAGED phone to the watch.

I have downloaded and installed the new iOS Watch 2.0.1 but the problem it is still there!

I have also updated iOS to 9.1 but the problem has not been solved.

Maybe my problem it is different from yours.

I can insert an appointment from my iPhone 5 and after few seconds it will be sync with my Microsoft Exchange calendar.

When I use apple watch to create an appointment it appears immediately on my iPhone (with Exchange calendar color!) but this appointment remain only on my iPhone. NEVER SYNCRONIZED with my Exchange calendar.

If I can do a small change (one letter on title) on this appointment immediately will be syncronized with my Exchange calendar.

It is really frustrating!
