If you want to offer your smartwatch the perfect and optimal display protection, then our UV light 3D armoured glass film is the best and safest choice for your smartwatch. This armoured glass film is applied with the help of a liquid, which is hardened using the UV lamp supplied. This prevents air bubbles from forming during installation. You should only use UV lamps when the entire armoured glass film is covered with the connecting liquid without air bubbles, otherwise the air bubbles can no longer be removed.
