Apple Watch cellular setup fails with 'Couldn't Sync iCloud Data' error

I have spent two days trying to set up my new Apple Watch Cellular with my iPhone 15, but I keep encountering a persistent issue. When attempting to configure the watch, I receive the error message: “Couldn't sync iCloud data,” with options to either cancel or delete iCloud data. I have repeatedly selected “Delete data,” but nothing happens, and the Apple Watch app on my iPhone simply displays a “Server error” message.

At this point, I’m frustrated and disappointed. I’ve spent £500 on a product that I can’t even use. Both my iPhone and Apple Watch are updated to the latest iOS, so I expected a smooth experience. This watch doesn’t reflect the usual Apple quality—it feels like a rushed cheap product, and I'm frankly fed up. Apple's products are deteriorating.

I was having the same issue and ended up going to the Genius Bar at my local Apple Store and they were able to figure it out. The issue was I had another Apple device (iPad in my case) with the Apple ID I was attempting to set up on the Apple Watch, and that other Apple device did not have a passcode setup/enabled. Once I put a passcode on the other Apple device, I was then able to enter that passcode on the new Apple Watch when asked and everything else in the setup completed as normal. Hope this helps.
