Oris - ProPilot X Calibre 400 Laser
It's actually a shame that this new product only worked in two dimensions. The titanium dial of the new ProPilot X Caliber 400 Laser has to be seen to be believed to experience this mesmerizing effect. If you move the watch slightly, the dial changes color, from blue to green, purple, like the color of iridescent beetles.
In fact, it is based on the principles of biomimicry, a phenomenon specifically found in nature called optical interference. This means that red light waves are dimmed while only blue and green waves are reflected. It's hard to believe, but there isn't a single drop of color pigment on the dial. This innovative treatment involves surface manipulation that splits the light into its component parts, creating a stunning rainbow effect that changes depending on the viewing angle.
