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.
