Struggled through latest update on iPhone for Iwatch. Now the iwatch is displaying message to continue on iPhone which is complete. Tried Pairing again but now wants the 6 digit code from Iwatch that is not displayable because of display to continue iPhone.

yesterday my Iwatch worked fine. Today not so much.

Start by tapping the "I" button on your Watch"bottom right corner", which will bring up your device's name. Then on your iPhone, tap the device name that matches the one displayed on your Apple Watch. You'll see a six-digit code will appear, which you'll enter on your iPhone.

I have same problem. My solution is to return the watch as I am still within my 14 day window.
