Some calendar events not showing on Apple watch

Just purchased an Apple Watch Series 3 running Watch OS 4.0.1 and encountered this bug within the first hour. Outlook meeting invites from another person that I have accepted do not appear on the Watch calendar unless I toggle the entry to private and back to not private. This bug means I cannot trust that the calendar on my watch is accurate. Very disappointing.

• This is to all. This is February 6, 2017 and my iwatch calendars still won't sync. 2 hours on phone with Apple and they are still working on it. Now I understand why I haven't used this watch for 6 months.

I have the same issue. They are Outlook events that I have accepted. They show fine on the iPhone calendar, but not on the watch.

Exact same issue as well, but the appointment will show up immediately as soon as it is marked as private on the iPhone's calendar. This definitely appears to be a bug.

I too have this exact issue - calendar requests do show up on my "modular" watch face, but when i click on the event, it opens the calendar app on the watch and the event isn't there. This is for meetings I have accepted.

Same problem for exchange invites I've accepted. Setting as Private as someone mentioned above makes it immediately show up on the watch. Please fix this major issue!

I'm experiencing the same issue. I haven't managed to nail down any consistent behaviour for what shows up vs. what doesn't, but exchange calendar events definitely don't always look in sync with what I see on the phone vs. the watch.

I Am experiencing the same thing! I have two Google calendars (1 personal and one a shared work calendar) and event from both calendars merge and show on my iPhone perfectly but only ONE calendar's events show on my watch. It's kind of important I get this to work too, as I cannot put personal events like haircuts onto my work calendar that is shared. Strangely enough the shared calendar is the one that shows on my watch and not my personal one. must be a know problem by the looks of things....come on Apple find a solution for us all!

Same issue here. An accepted invitation from someone outside my organization showed up on Outlook and also on my iphone and ipad. It did not show on the watch. Setting it to private made it show up immediately. I took it off of private, and it appears to be staying. Please fix this, Apple!

Same issue, though it seems to be related to meetings I have been invited to, or repeating events. I tried marking "Private" on an entry that wasn't showing in my Exchange calendar (which I accepted an invite for) but it switched back. Still not showing on watch.

Same issue here. Seems random but if you can't rely on your calendar there is a problem.

Add one more to the list.

Same issue: some events do not display on the watch calendar, glance, or complication. Like others, the common thread appears to be events that originate via email invitation.

Thanks for the tip on setting to Private - crappy workaround, but better than forcing a re-pairing every day.

I'm also having this issue with Exchange calendar events, and it seems like I've found a temporary workaround (but it doesn't last forever).

Go to the Watch app on the iPhone and go to General > Reset > Reset Sync Data. This will resync calendar and contacts data. After hitting this button (there is no feedback telling you it's working), the calendar event will re-appear on the watch.

It might work for a while, but then it'll happen again (at least it does for me).

Similar issue, on my watch face it says not events today but when I open the calendar the event is present (on the watch).
