Watches glasses - What are the differences?

For some buyers of a watch, durability and quality are important, for other buyers the price is decisive. You are looking for a watch and come across all kinds of different terms; crystal glass, mineral glass, plastic glass and sapphire glass. But, what do these types of glass actually mean and how do they affect the price?

Plastic glass is a type of glass that is usually developed for the cheaper watches. It is a light type of glass that is very difficult to break, partly due to its flexibility. Cheap and difficult to break sounds interesting. So what's the catch? Because plastic is a softer material, it can be damaged quite easily, which is a shame if you are very happy with your watch and would like to use it for a longer period of time.

Mineral glass is about seven times harder than plastic glass. This makes it scratch resistant, but at the same time more fragile. The production of this glass is done by heating glass crystals. The advantage of mineral glass is that it is very clear and can be repaired quite cheaply.

Crystal glass is about three times harder than mineral glass. This makes it slightly more exclusive than the previous two types of glass. It is scratch resistant and less likely to break than mineral glass due to its hardness.

The most durable of the different types of glass is by far the synthetic sapphire glass. Due to the hardness of this glass, it is very scratch resistant and will only be damaged under extreme conditions. It is the strongest, clearest and most durable watch glass there is. The hardness of this type of glass has a 9 on the Mohs scale. That is only surpassed by diamonds.

Olivier Bruyneel watches has put a lot of emphasis on quality and durability. A timeless design with a beautiful world map in the background, protected by highly scratch-resistant sapphire glass, ensures that you can enjoy your watch for as long as possible.
