The last time we tore down an LG smartwatch, we were pleased to find screws securing an o-ring sealed rear door. Today we're heating our iOpener and feeling a little sad.

However, thanks to a handy pry notch, things aren't too bad. But you will need to replace the adhesive before re-sealing the watch, to maintain that IP67 water resistant rating.

IP67 is a water and dust resistance rating that guarantees the device to be dust-tight, and able to survive submersion in 1 meter of water for 30 minutes.
