• Drain the battery below 25% before you start on this repair. A charged lithium-ion battery can catch fire if it's punctured or damaged
• Power the watch off and take it off its charger before you open it
• Warm the display edge with the iOpener, then cut the adhesive with the knife, no more than 2 to 3mm in, so you don't cut the display cables. Use the iFlex on the display edge only, never near the battery
• Open the display only to about 45 degrees: its cables are still connected underneath
• The display cable sits in a ZIF connector. Peel its tape back only partly, lift the lock bar and slide the cable out, then push it fully back in before you lock it again
• Track your screws on a magnetic mat and handle them with tweezers, so each tiny screw goes back in the right place
• The battery connector sits under a bracket held by a 1.1mm Y000 screw. Remove the bracket and lift the connector straight up with a spudger
• Keep metal tools away from the battery, and never bend, crush or puncture it. Lift the old battery slowly with a plastic pick, keeping it shallow, as the display cables run underneath it
• Remove every bit of the old battery adhesive and clean the case with isopropyl alcohol. Peel the liner from the new battery's adhesive, press the battery into place and reconnect it, then check the watch powers on and charges before you seal it
• Clean the old display adhesive off the case and the display with isopropyl alcohol, then fit new precut LCD screen adhesive, or run a thin bead of B7000 glue around the case edge, and press the display down evenly while it sets
• If your watch doesn't turn on after the repair, force restart it: hold the side button and the Digital Crown together for at least 10 seconds, until the Apple logo appears
