Your Kogan IP68 Multisport GPS Smart Watch comes with a protective plastic film installed on the screen to protect it in transit.
If there is any bubbling on the screen when your watch first arrives, this is due to the application of the protective plastic film:
Carefully remove the protective film by peeling it from the edges to reveal the new screen underneath.
If you find that the screen itself is damaged, please contact Kogan.com Support.
