Plastic and mineral crystals were yesterday's standard. Today, proper
luxury watches use sapphire crystal as a cover and protection. In our shop too, you will find some
women's wristwatches and men's watches with sapphire crystal. But why is sapphire crystal so robust, and is it indestructible? Learn more in this article about the properties of sapphire crystal and discover ladies' and men's watches from our shop.
The king of watch crystals
Sapphire crystal is considered the "king of watch crystals." It is actually as hard as sapphire. Only diamond and a few other materials such as tungsten carbide are harder. Sapphire crystal is synthetically produced using the Verneuil process and is highly pure aluminum oxide. Nevertheless, it should not be treated with diamond-coated tools or pointed objects in any way, or struck against them. Even though sapphire crystal is scratch-resistant, it sometimes seems as if small scratches have formed despite the manufacturer's promise. But most of the time, this is just abrasion.
This means that softer metals have left their marks on the sapphire crystal. However, these can be removed quickly and easily with a standard eraser. By the way, you can easily distinguish sapphire crystal from inferior mineral glass by placing a drop on the glass. If the drop runs down easily, it is mineral glass. But if it stays in place and only runs down slowly, it is sapphire crystal.
Our wristwatches with sapphire crystal
We have selected a ladies' watch and a
men's watch for you that have a watch crystal made of sapphire. The Citizen CB0230-81E is a high-quality radio-controlled wristwatch from the Promaster series and is therefore also a dive watch. For dive watches, it is especially important that the dial is protected from water ingress, which is why sapphire crystal is particularly well suited for this purpose. Our ladies' watch is a Bulova watch. The stylish and elegant
wristwatch impresses with its high-quality design. A two-tone stainless steel bracelet, rhinestones on the dial, and the scratch-resistant sapphire crystal make this watch something very special.
