Some calendar events not showing on Apple watch

Try unlinking and relinking your watch. This solved the problem for me. Make sure you are backed up and you will get an option to restore it when you relink. Hope this helps.

Have done that multiple times, including moving to a new 6S+ from a 5S, unlinking/relinking several times. I even started fresh on the watch (didn't restore from a backup) when going to the new iPhone. No joy.

Me too, Watch 2.0, 9.01 and calendar events schedule by others not showing on watch

Another IBMer here and I experienced the same thing.

Unpairing and then again pairing did it for me.

I spoke again with Apple support yesterday, although this time with the 4th level of support, and they have confirmed finally that they acknowledge there is an issue with how MDM is working, and suspect it could require a fix on both Apple's and external MDM soft systems to resolve.

Apple wanted screen shots of my MDM profile and restrictions to help clarify the issue, and said to expect another patch shortly in the future - not sure if it will be an iPhone or Watch update

For the IBMers out there, I have raised this internally to our Traveler team, and they are already engaged with Apple on this through our partnership.

Thank you! I hope the patch comes soon.

I did a complete wipe of my phone and re-built it and re-paired with Watch. Calendar events showed up just fine until I added MaaS360 and IBM Traveler. Then no events appeared even from iCloud calendars.

This is still an issue for me. I just purchased the watch with apple care. Is anyone in apple working on this issue ? I think it is a very important feature the most important besides telling the time i.e. what's my next appointment.

I don't have any issues anymore, latest iOS and WatchOS Releases running; even in my MDM managed environment everything fine.

I have the same issue as everyone else. Calendar entries appear on the iPhone correctly but are not showing on the Apple Watch. Unfortunately I have now lost confidence on the calendar on the watch and have to confirm all days meetings on the iPhone before continuing.

The meeting appear on the iPhone correctly but does not appear on the Apple Watch. The original meeting request comes from Lotus Notes and I am using Awesync to sync my Notes calendar with a Google Calendar. The google calendar is then synced with the iPhone, which in turn, displays them on the watch. Long way around, but it works (most of the time).

In Lotus Notes, if I copy the missing entry to a new entry (same time, place, date, etc) that new duplicate entry filters down to my phone and appears correctly on the Apple Watch. For some reason, there must something wrong with the original meeting request is is not allowing it to be displayed on the watch.

The iWatch only sync well with the default iphone's calender. Goto: Setting->Mail, Contacts, Calenders->Default Calender, Choose whatever account you want to create your events in (e.g. Work in iCloud). Then in future events that you create in the Calender, just make sure it is created in the same account.

It is annoying and Apple, please fix this problem in WatchOS3.
