Hello atierney65,
Thanks for asking the Apple Support Communities about your Calendar events not showing on your Apple Watch.
First, please check the settings and all info here: Check and update your calendar on Apple Watch - Apple Support
Are your events syncing with the paired iPhone? If not, check the troubleshooting here: If your iCloud Contacts, Calendars, or Reminders won’t sync - Apple Support
If this is only occurring on the Apple Watch, that second article also has you check sync: "Force sync Calendar data on Apple Watch
To force sync Calendar data on your Apple Watch:
- Open the Watch app on your iPhone and tap the My Watch tab.
- Tap General, then tap Reset.
- Tap Reset Sync Data.
If a family member set up your Apple Watch for you, you can't force sync Calendar data. "
Thanks and have a wonderful day.
