Clear Transparent Smartwatch Sapphire Glass For Smart Wearable Device
Product Description:
Anti-reflective sapphire glass mulai digunakan oleh brand asal Swiss pada pertengahan tahun 2000. Jam tangan Panerai seri terbaru menggunakannya sebagai standar. Begitu juga Patek Philippe, Audemars Piguet, Omega, Tag Heuer, dll.
Kelebihan anti-reflective sapphire glass adalah kombinasi ketahanan sapphire crystal dan bahan campurannya yang mampu memantulkan bayangan dan cahaya. Tidak seperti anti-reflective coating, anti-reflective sapphire glass tidak menampakkan warna kebiru-biruan pada crystal jam.
