Sapphire crystal refers to a synthetic material used in the watch industry, known for its exceptional hardness and scratch resistance.

Part of speech: noun
Definition: In the watchmaking industry, 'sapphire crystal' pertains to a synthetic sapphire produced through a crystallization process that results in a material nearly as hard as natural diamond. This incredible hardness grants it superior scratch resistance, making it an ideal choice for the protective cover over the watch face. Unlike mineral glass or acrylic, sapphire crystal can withstand the rigors of daily wear, significantly enhancing the longevity and maintaining the pristine appearance of timepieces. Its transparency and clarity also ensure that the watch dial can be viewed without distortion. Due to these properties, sapphire crystal is predominantly found in high-end watches, where durability and aesthetic appeal are paramount.
