The Apple Watch screen is protected by a sapphire panel, but only if we are talking about the stainless steel and Edition models, this is because the Sport model does not use such a material. Even so, based on sales estimates for the stainless steel Apple Watch and the Apple Watch Edition, analysts say that Apple will consume a fifth of the global production of sapphire watch panels. According to those with sources in Apple's distribution chain, Aurora Sapphire and HTOT supply its sapphire panels, both being traditional producers of such materials.
Unlike GT Advanced which tried to evolve with the help of Apple, Aurora Sapphire and HTOT have a lot of experience in producing sapphire panels, the latter company supplying this type of components for Apple for the first time. Although these companies supply the raw panels for Apple Watch, Lens Technology and Biel Crystal Manufactory finish the component for application over the Apple Watch screen. Apple has been using sapphire for years to protect iDevice cameras and Home buttons, starting with Touch ID, so it knows where to buy cheap and good products.
