Add a new dimension of wonder to your style with the Blackest Swiss Made Self-Winding Watch by Chronotechna. This incredible watch actually uses aerospace super-black coating, the darkest man-made substance. Reminiscent of a black hole, the Blackest Watch face actually absorbs 99.9% of incident light. Because of this, you can see the face in virtually any conditions, including direct sunlight and even underwater. Pairing with this incredible design is complete with Grade X1 Super-Luminova. Even in lower light, the hands and indices stand out with exceptional color. Inside the 316L stainless steel case is a Swiss automatic self-winding movement. It has a power reserve of 42 hours with a daily accuracy of -10/+10 seconds. Finally, all of this stunning design is complete with an interchangeable premium handmade Italian leather strap with a quick-release band system.
