We make the open-heart display window lens from a photochromic sunglass worn by pilots. This lens will darken with the intensity of the UV. We named this technology “Umbra”. Resembling the lunar eclipse when the sun is blocked by the earth, Umbra lenses present this astronomic beauty on the watch, making it more interesting.
