Iwatch
hello, i just got my new iwatch, and i’m having trouble synchronizing the watch to my iphone
Apple Watch Series 6, watchOS 7
What kind of trouble is that? Is it a brand new watch or was it paired with another iPhone before?
See here for detail guidance how to pair the watch with an iPhone
Set up and pair your Apple Watch with iPhone - Apple Support
Check the Trouble pairing? section in there as well.
