Watch glass refers to a transparent shield over the surface of the clock. There are many different materials, which are used to manufacture watch glasses. They are usually made from one of three common materials depending on the brand, quality and uses of each watch. Each material has its advantages and disadvantages, so we understand the difference. Sometimes the glass is referred to as crystal, it should not be confused with the quartz crystal inside lots of watches, which regulates the timer.
Acrylic
The cheapest glass is actually plastic. acrylic plastic is strong, flexible and transparent. It can not destroy it, because it is very light. The downside is that you can easily scratch. Scratches can be removed, it is advisable to consult a jeweler about the best way to proceed. Children's watches are often acrylic glass, because they are not enough unlikely to be able to break even if they are not as careful as can be!
Mineral Glass
Most common form is a glass of mineral glass. This is accomplished using heat and chemicals in the treatment of ordinary glass to make it more resistant to scratches. If the glass is too scratched, will have to be replaced. Unfortunately, also affects the glass to make more disintegrate. From time to time, when the watch a small storm of glass shards of glass may consist of the excavation. If that happens, the cost of repair may exceed the value of the watch. Most of the watches, but not the end of their life in this way, so it need not be overly worried. But we should be careful, if the watch is broken glass, to prevent such a situation.
Sapphire Crystal
Watch the most desirable Glasses are made from synthetic or sapphire, or true. Synthetic sapphire is commonly used. This is made from crystalline aluminum oxide has the same characteristics Natural as the natural gem often used in jewelry, but without color. It is the most expensive way to create a watch glass, but the advantage is that the glass is extremely durable. Price Sapphire 9 in Moh scale (that is, on a scale that measures the relative hardness of all materials), and right for the diamond which measures the 10th All glasses are least likely to break or scratched. If something should be more concerned that the watch can damage the other surfaces! Sapphire is one of the features that are pushing the high end of the offer price. This is due to the value of sapphire and semi- because the use of expensive tools to cut sapphire and diamond shape have to be used to produce them. Premier brands such as Seiko and Citizen watches sapphire glass, often use their services.
