Everything is achieved via a laser treatment that changes the watch’s titanium dial in such away that the light waves that get reflected back to your eyes only contain a certain spectrum of the visible light, and therefore give you an impression of color. Normal light contains all the colors of the visible spectrum (and more that are not visible). If a certain range – the longer red waves, for example – gets destroyed, only the medium green and shorter blue waves get reflected. It’s color creation by addition. We’ve also added a second layer that splits the visible light into its components and creates a shimmering rainbow effect. How you see this depends on your viewing angle.
