Sapphire Watch Window
In the late 1960's, conventional inorganic glass used for sapphire watch window (cover glass) was rapidly being replaced with single crystal sapphire - an artificial jewel.
Orbray's technological capabilities are highly valued in the Swiss watch industry, as Orbray has been able to meet the demand of recent design trends for uniquely-shaped sapphire watch window while still maintaining the high quality that is essential for luxury watch components.
Pink sapphire
While sapphire watch window is generally colorless and transparent, colored cover glass is also in demand for limited luxury watches. Using the EFG method, Orbray succeeded in mass growing uniformly-colored, large sized, single crystal pink sapphire. The pale pink sapphire watch window can bring about an unparalleled, elegant design with the hardness harder than the normal sapphire (Hv=2200)
