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
