This scratch, shock and drop-resistant screen protector from PanzerGlass keeps your watch safe from just about anything life might throw at you. The front is made of tempered glass, while the transparent plastic frame is made with D3O Bio, the world's most advanced plant-based protection material, trusted to protect military elite forces and professional athletes alike. And to make sure the strength is top notch, the screen protector has been drop-tested under 1 x Military Grade Standard conditions. That means it can withstand several drops from a height of 1.2 meters or a groping-around-in-the-dark-and-accidently-knocking-your-watch-off-the-bedside-table kind of height.
