The COTEetCI 4D Tempered Glass provides comprehensive, high-grade protection for the screen of your Apple Watch Series 7 (45mm). Engineered with a real 4D curved edge design, this protector ensures total coverage, extending protection beyond the flat screen surface and incorporating a stylish black frame around the edges. Built to withstand daily wear and tear, the glass boasts a 9H surface hardness, making it significantly stronger than regular plastic PET film. This high resistance level provides effective defense against scratches, bumps, and sharp objects, ensuring your watch display remains pristine. Furthermore, the surface is treated with a nano-coating, making it anti-fingerprint and resistant to hand perspiration, allowing for easy cleaning with a simple wipe. Despite its protective capabilities, the COTEetCI 4D Tempered Glass maintains exceptional visual quality. It offers high transparency with a light transmission rate of over 98%, ensuring that the brightness and clarity of your Apple Watch display are not diminished. The ultra-thin design is engineered to maintain high touch sensitivity, ensuring that the protective layer does not impede the watch's functionality or responsiveness. Installation is designed to be straightforward, though care is advised. The product is specifically cut for the Apple Watch 45mm model, ensuring a perfect fit. The combination of its durable, scratch-proof material and its elegant, crystal-clear finish makes the COTEetCI 4D Tempered Glass an essential accessory for maintaining the aesthetic and functional integrity of your device.
