For protection against surface scratching, we offer a case steel that has been hardened to about 1200 Vickers on some of our models.
The hardened layer acts like a protective coat around the case,continuously merging with the hardness of the base material. The surface of a watch case featuring Tegiment is far better protected against scratching than a normal steel watch Area.
