I can’t unlock my IWatch after I changed iPhone. it says it is already paired with my old iPhone but I erased that iPhone entirely (forgot to unpair the watch before doing it though) so now it is not paired with it and it does not let me pair it with the new one. I tried reset manually (press crown button while placed on the charger it doesn’t work either

Apple Watch SE, watchOS 7
My old iPhone is now completely erased , so when I open it I need to set it up again and the Apple Watch app does not recognize my watch , it asks me to pair it again.. :( so it is not paired to any of the two phones
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.
Thanks you very much , it worked :)
You have to unpair it from your old phone here;
