100% SWISS MADE SAPPHIRE CRYSTAL

Only diamonds are harder than sapphire crystal. With a hardness level of 9 Mohs sapphire crystal is second in the ranking. Our watch crystals we use on the SWISS MADE version of our PEARL DIVER are made of synthetic sapphire, produced with the so called Verneuil-Method. (click for more information)

The Verneuil method (or Verneuil process or Verneuil technique), also called flame fusion, was the first commercially successful method of manufacturing synthetic gemstones, developed in the late 1883 by the French chemist Auguste Verneuil. It is primarily used to produce the ruby, sapphire and padparadscha varieties of corundum, as well as the diamond simulants rutile, strontium titanate and spinel. The principle of the process involves melting a finely powdered substance using an oxyhydrogen flame, and crystallising the melted droplets into a boule. The process is considered to be the founding step of modern industrial crystal growth technology, and remains in wide use to this day. (WIKIPEDIA)

We entrusted SEBAL SA with the production of our sapphire crystal for the watches. A Swiss Company producing sapphire crystal products for various famous Swiss Brands since 1978. Their longterm experience with hard materials led us to work with them and we did not regret it. With the help of state of the art machines, they are able to work with these hard materials very precisely.

Here is a shoot of the production:

As you can see, our SWISS MADE PEARL DIVER feature a true "gem" stone in the front and it will certainly protect your watch face and thanks to the UV filter, help to keep the colors fresh like on the first day.

All these premium features are coming with a price of course. Costing about 12 times the price of an Asian made Sapphire Crystal. But we wanted to do something special for our Swiss Made model and the customer feedbacks are all very positive.
