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.
Then follow the onscreen instructions to finish pairing your watch.
