Hey 100rab,
I understand that you're having some trouble with pairing the Apple Watch to the iPhone. I'll be happy to help out.
It looks like from the picture that Bluetooth is not turned on for the iPhone. Make sure that Bluetooth, as well as Wi-Fi, are toggled on for the iPhone. If that doesn't help with pairing, try restarting the iPhone and Apple Watch.
Restart your iPhone, iPad, or iPod touch
