    About Custom
    Product parameters glasssurface technologypolishing ,chamfermiddle height random.contace me if you have other specific needsThese round sapphire glass crystals come in a variety of thicknesses and diameters, are nearly unbreakable crystals making them highly prized by watchmakers. These watch crystals can be glued into most watch cases or pressure fit into most plastic watch crystal gaskets. Each sapphire watch crystal comes with a slightly polished bevel edge to give the watch crystal a nice finished look once it has been installed. These generic sapphire glass crystals can be used to replace the watch crystals of almost every name brand watch popular today, especially high-end watch crystals like those in Rolex watches, saving you both time and money. Except for sapphire glass, if you need another watch part, please contact me.Welcome to long-term cooperation. Please try to offer more details as below when you place an order: 1. Buyer offers an original sample or related mounting parts and special request for attention or change. 2. If you can not offer a sample, please try to offer more details as possible as you can

    About Sapphire Glass
    SAPPHIRE CRYSTAL (sapphire glass) generally refers to synthetic sapphire, generally used in the manufacture of the watch glass.
    It is resistant to wear with tungsten titanium alloys and high-tech ceramics. but sapphire materials can wear resistance and
    withstand the strong impact, and some of the same or higher hardness of the material (e.g., millstone, sandpaper, nail, granite,
    concrete wall, and floor, etc.) so sapphire glass are not likely to scratch the surface of these materials.
