Be warned the adhesive ifixit sells does not work! I used 3 strips following this guide to a T and each time the screen popped off after a few hours of wearing. Just buy a new watch.

Thank you for your answer. So basically I don't need to transfer any parts from the old screen to the new screen in order to keep the full features.

Does anyone know if the screen is paired to the device? As in if I replace the screen will I still have true tone?
