For all our watches we have made the choice to work with 316L steel, this alloy is recognized for its durability and also its great resistance to corrosion, two elements which we consider essential for the boitier of our watches.
From an aesthetic point of view, 316L steel is a stainless steel whose brightness lasts in time and does not tarnish. It also recycles very easily and in full.
The sapphire glass is obtained from aluminium oxide crystallized at 2050 °C, it has the same chemical properties as the natural sapphire. Thanks to this the sapphire glass is a very resistant component, it is the second most hard material after the diamond (it is for example 7 times harder than the hardened steel).
Thus the sapphire glass is a glass that breaks or is very difficult to scratches, it will cross the time to wonder with your watch.
