Step-by-Step Process
Step 1: Power down your watch
Before starting repairs, take your watch off the charger and power it down.
Remove the watch band.
Step 2: Unscrew the back cover
Use a Tri-point Y00 screwdriver to remove the four 4.0 mm-long screws securing the back cover.
Step 3: Pry open the back cover
Insert an opening tool into the seam between the back cover and the metal housing.
Twist the opening tool to create a gap.
Don't try to remove the back cover all the way yet. The sensor flex cable is still connected to the motherboard.
Step 4: Disconnect the sensor flex cable
Lay the watch face down.
Carefully swing open the back cover by folding it to the opposite site of the created gap.
Use the flat end of a spudger to pry up and disconnect the sensor flex cable from the motherboard.
Remove the back cover.
Make sure the rubber gasket is undamaged. If damaged, replace it with a new one during reassembly to maintain proper water resistance.
Step 5: Disconnect the flex cables
Use the pointed end of a spudger to disconnect the hall sensor-, the display-, and the crown button flex cable.
Step 6: Unscrew the motherboard
Use a Phillips screwdriver to remove the 4.4 mm-long screw securing the motherboard.
Step 7: Remove the motherboard
Use your fingers to lift the motherboard out from the watch assembly towards the bottom of the watch.
During reassembly, make sure none of the flex cables become trapped underneath the motherbaord.
Step 8: Remove the core assembly
Place the corner of the flat end of a spudger [link|https://guide-images.cdn.ifixit.com/igi/DWVpLVtrHTSFfHIb.full|in the small opening|new_window=true] of the barometric sensor, on the opposite side of the display connector.
Twist and tilt the spudger to lever the core assembly out of the metal housing.
Thread the display flex cable through the opening in the core assembly.
Remove the core assembly.
Step 9: Heat the display
Step 10: Separate the display from the watch frame
If your display is cracked, keep glass shards contained by applying a strip of tape over the glass.
Use your finger to steadily push the display down through the watch's metal housing to separate the display from the frame.
Remove the display.
