In addition to the good mechanical characteristics of DLC, the DLC coating also impresses with excellent biocompatibility. DLC coatings do not contain any allergenic metals and additionally serve as protection against nickel contents.

Watch cases coated with DLC have a longer life span. Due to the hardness of the DLC coating, accidental intrusion of hard particles or damage is almost impossible. The dial and movement are also protected by the stability and robustness of the DLC case.

In addition to its outstanding protective qualities, each timepiece with a DLC coating stands out with its particularly elegant and aesthetic appearance. Our Topograph and Zirkel Edition Bauhaus have a deep black finish that is suitable for every occasion and every style of outfit. The perfect combination of sophisticated technology and aesthetics.

Nobody wants scratches on their watch. Whether on the glass or the case. Stainless steel can also be scratch-prone when exposed to other harder metals. The harder the case material, the more scratch-resistant the watch. For this reason, DLC-coated housings are extremely hardened and thus more scratch-resistant than PVD material.

First (Front) Surface Mirrors This product has the reflective surface on the first or 'front' surface of the glass. First surface mirrors are used in imaging equipment and applications where the reflected image must be not pass through the substrate. This eliminates the slight bending of light that occurs when an image passes through the glass, reflects off the back, and then returns through the glass as with commercial mirrors. This coating is commonly specified on our custom ground and polished optics. For stock purposes, the 97% reflective mirror coating is put on the front surface of float glass with a clear SiO2 protective coating. However this coating is still very sensitive to scratching and is further sprayed with a light blue coating that must be pealed off prior to use.

Despite the robust character of a DLC-coated watch, the smooth surface of the DLC coating ensures that it feels comfortable on the wrist. The smoothness of the casing precisely reflects the characteristics of the graphite content of the black DLC coating.
