Blackout concept also chose this material.
Recognized for its many qualities, stainless steel is the one that best illustrates this evolution in the dressing of wristwatches.
It is interesting to note that luxury watch brands, accustomed to gold and platinum, quickly adopted it with a preference for 316L steel – also known as surgical steel.
Robust, non-allergenic and resistant to corrosion, it sometimes benefits from surface treatments that improve its qualities, such as PVD (Physical Vapor Deposition), DLC (Diamond Like Carbon) or BOC coating (DLC base) * on our customizations.
More efficient but rarer, the 904L steel, used by Rolex, is for example exploited in the space sector and the chemical industry. The manufactures size Oyster cases in massive Oystersteel steel blocks belonging to this family of super alloys.
* The black treatment B.O.C (Blackout concept) is a unique innovation created after several years of research thanks to the assistance of physical engineers in Geneva. They also managed to find the best possible ultrasound treatment, thanks to the chemistry NGL of Nyon (VD). The preparation before treatment is of great importance.
When the maximum results are achieved, our work can begin.
We will keep our development technology secret. In addition, we will surely remain for a long time the only company to offer a 10-year warranty on the BOC (Blackout concept) treatment. Our technique brings a result of incomparable brilliance and depth of black.
We are close to the ceramic keeping the shades of steel. Also know that the treatment B.O.C (Blackout concept) does not fear the scratchs.
B.O.C. Treatment = Quality, Resistance and Longevity
