Advantages & Disadvantages of Acrylic Crystals on Vintage Watches
While all advanced Rolex watches are fitted with crystals make from profoundly scratch-safe engineered sapphire, more established Rolex watches were produced with crystals produced using a plastic-like material known as acrylic. The primary Rolex watch to at any point be fitted with a sapphire crystal was the reference 5100, Rolex’s first-historically speaking quartz watch that was delivered as a restricted arrangement and controlled by the Beta-21 development.
