Out of the commonly used types of glass available today, the sapphire crystal, on a watch provides the sturdiest form of protection from scratches. Due to its hardiness and quality material, this category is easily seen to be equipped with higher-grade timepieces.

With its renowned exclusivity and sturdiness, many watch enthusiasts look forward to owning watches paired with sapphire crystals. Read on to find out what it really is and the magnificent timepieces housing this wonderful type of glass.

What is a Sapphire Crystal Watch Glass

So, exactly what is a sapphire crystal watch glass? Well, it’s a dial covering providing a certain amount of hardiness. First invented in the 1960s, it’s renowned for its robustness as indicated by a 9 out of 10 on the Mohs scale, a measurement to calculate mineral hardness.

A sapphire crystal is made from a synthetic material as a result of crystallizing pure aluminum oxide at very high temperatures. Afterward, these raw sapphires go through a refined, costly process requiring special tools to slice, ground, and polish them. 

It’s then not so surprising that this type of glass is usually evident in the more premium timepieces.

Another prominent feature of sapphire crystal in watches is its clarity. As has been mentioned, the material is without a doubt, pretty hardy. Now, this results in a higher reflection on the glass.

Not to worry, most sapphire crystals in watches are applied with one or more layers of anti-reflective coating to bring the best legibility in reading time.

Now that you understand what sapphire crystal in watches really means, here are a few timepieces that bear the hardy and fantastic glass. All are worth adding to your collection of stunning timekeepers.
