I forgot my Apple Watch passcode , I try to follow step to reset but it's still not work

Hi!

I see you forgot your passcode on your Apple Watch. If you have access to the Watch app on your iPhone, open it, then press on All Watches in the top left. Then, press the info button in the right of your Watch. Then, select Unpair. This will reset Apple Watch to factory settings.

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.
