not able to pair Apple watch

Can you be more specific (error messages, etc.). Without knowing anything else, perhaps these articles will help:

Set up your Apple Watch - Apple Support

If your Apple Watch isn't connected or paired with your iPhone - Apple Support

I had not used my I watch in about 3 years since it had stopped working/wouldn’t charge. I was a few days out of warranty when I went into an Apple store so I thought I was out of luck. It wasn’t until this week that I figured I’d try charging it to see if by any chance it would come back to life; well it did. It’s prompting me to select a language and country, no issues there. When I get to the step to pair, my iPhone 11 isn’t reading the image nor the watch’s code for me to pair it manually. What else can I do/try?

If you have the apple id that paired the watch to this phone you don't have then you can do this;

To unpair and erase watch and remove Activation Lock.

On a computer, go to iCloud.com and sign in with your Apple ID.

Go to Find Iphone.

Select All Devices, then click your Apple Watch.

Click Erase Apple Watch.

Select Next until the device is erased.

Click the remove button next to your Apple Watch.

I have the same Apple ID, so logged into iCloud but the watch isn’t listed as a device on my account. I’ve also already tried resetting phone and watch, reset network settings on my phone, and confirmed airplane mode isn’t on.

Seems like my phone finally picked up the code, but it’s giving me a message I confirmed that the watch and my previous phone are not set up as a device under my iCloud account

You'll have to unpair it from the last phone it was paired too,you can only pair a watch to one phone at a time.

What if I no longer have that phone?

I tried but wasn’t successful. :(

I do not own a apple watch or computer or any other device you listed accept my iPhone 8.
