This year, Chronoswiss will provides a variation on its signature Opus watch – the skeletonized automatic Opus Chronograph and Grand Opus Chronograph, both of which are now available in black.  These watches get their “black magic” from Chronoswiss’s “Dianor” DLC (diamond like carbon) coating process.  I do not get the sense that “dianor” is anything exceptional, but rather the brand name that Chronswiss has chose to use for marketing effect.   Chronoswiss does claim, however, that Dianor is different from many commercially available coatings and is the result of an original, patented process.  “Using a pulsating ray of light, a plasma is created in a vacuum environment that is aimed at the substrate to be coated. Thus, a much higher amount of diamond is created that produces more than double the hardness of the coating.”  Minutiae.

The model still maintains the classic Chronoswiss characteristics with a fluted screw-down bezel, screw-down polished case back in addition to a solid metal oignon-style crown and screw-in lugs with patented Autobloc System. The hands are painted bright red and/or luminous white.
