Step 3

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.

That isn't glue holding the cover in place. That is the rubber gasket used to waterproof the device. It WILL get damaged and you WILL have to replace it.

Step 4

Lay the watch face down.
Carefully swing open the back cover by folding the back cover 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.

Step 5

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.

Conclusion

To reassemble your device, follow these instructions in reverse order.
