Step 1:Connect the charger to the iWatch. although the iWatch comes out of the box with a full charge, for safety, just plug in the charger that comes in the package and broadcast the magnetized end to the back of the iWatch.
Step 2:Turn on the iWatch. you can press the button on the side for 1-2s and then you will see the Apple logo. Then, select the language and continue.
Step 3:Open the iWatch app on your iPhone. A message will appear on your iWatch asking if you want to open the iWatch app pre-installed on your iPhone (assuming you have updated to iOS 8.2 and above). Click Agree, and the connection process will begin.
Step 4:Point your iPhone's camera at the iWatch screen. Just follow what the app asks you to do and try it out, and it should pair successfully and automatically. Upon success, a dynamic point cloud will show you that you have been successfully paired. If it fails, pair manually: Tap "I" on the iWatch's display and you'll see it list the iWatch's device name.
Step 5:Agree to all the terms and set a passcode. Once this is done, you will be asked to receive terms and conditions, Siri, diagnostics and support for your device via iCloud. These are not options, they are mandatory. You will also be asked to create a password. Minimum 4 digits or longer.
Step 6:Decide if you want your iPhone to lock your iWatch. a message will pop up on your iWatch asking you this question. It basically says that once your watch is on your wrist and paired, you don't need to enter a passcode. Click Yes (if you change your mind later).
Step 7: Wait for the sync. iWatch traverses all your apps and loads the ones that are appropriate for IWatch. A slowly filling progress circle indicates your progress. This can take upwards of 10 minutes. So keep your iPhone handy and charged, with your iWatch next to it, and you're ready to go have a drink.
