Hi brenton184,
It sounds like you need help pairing your Apple Watch to a new iPhone. If so, be sure you have the following below found in the article here: How to pair your Apple Watch with a new iPhone - Apple Support
"Here's what you need
- Your Apple ID and password (so you can turn off Activation Lock)
- Your old and new iPhone both need to be connected to Wi-Fi
- Your Apple Watch and iPhone both need to be at least 50 percent charged
- Your Apple Watch passcode (get help if you forgot your passcode)"
Based on the devices or access you have to the prior iPhone follow the remaining steps in the article to transfer your data and pair.
As mentioned in the last section from the same article:
"If you transferred your content to your new iPhone using your computer, but Health and Activity content is missing
If you use iCloud to keep Health up to date on your old iPhone, your data will automatically update on your new iPhone whenever you're connected to Wi-Fi and signed in to iCloud. On your old iPhone and your new one, go to Settings > [your name] > iCloud and make sure that Health is on.
If you don't use iCloud, you can try to restore from a computer backup of your old iPhone. If you have your old iPhone and didn't erase it, make a new iCloud backup or encrypted computer backup. Then erase your new iPhone and restore it from the new backup. Remember to pair your Apple Watch and iPhone again. If you use a computer, make sure that you encrypt your backup.
If you don't have your old iPhone or you can't back it up, you can't recover your Health and Activity content."
Hope the information helps.
Cheers.
