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.
