Swollen sapphire glass
The Concordia is equipped with a#x27special glass, the challenge was to create an ultra-resistant watch that remains perfectly legible. We l 'have therefore endowed d ' a bulging sapphire glass, anti-glare treated, d ' a thickness of 3 millimeters.
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.
