This article explains how you can fix when your calendars won’t sync. Your Apple Watch Face may display the wrong date and events you created or updated aren’t showing correctly on your Apple Watch. You may experience this problem with various calendar services, such as Google Calendar, Exchange ActiveSync, or Apple Calendar etc. For example, your watch may show incorrect date and time information and may say “no more events” even though you know there are events.
Your Apple Watch face can be customized. You can personalize your clock face to display the Calendar complication. However, this would be useless if your calendar information did not update and sync with your iPhone or iCloud account.
