Does Rolex use sapphire Crystal?
By 1991, the Rolex Perpetual was the last watch to possess a acrylic crystal. Now, all Rolex watches feature the sapphire crystal. Some versions, such as the Datejust also feature a small Cyclops lens, which magnifies the date through the sapphire crystal. Sapphire crystal outperforms mineral glass in durability, scratch resistance, and long-term performance for serious watch applications. From our experience supplying military units, the choice between these watch crystal materials determines whether your timepiece remains functional when conditions deteriorate.Quartz watches are tough and can easily last for decades with a little care and the occasional battery change. On the other hand, automatic watches, with their intricate mechanical movements, can be passed down through generations with some regular servicing and good maintenance.
