The Perseid meteor shower expressed by the "Nanoparticle Metal Layering Technology"

Created using "Nanoparticle Metal Layering Technology", the dial captures the beauty of a meteor‑lit night sky. Its expression shifts with light, recalling the fleeting brilliance of the Perseid meteor shower. A subtle gradation deepening toward the perimeter, enhanced by a clear coating, evokes the profound depth of outer space.
An uncompromising devotion to detail, enhancing a sharp brilliance

Hands and index, meticulously finished with contrasting hairline and mirror surfaces, along with the diamond‑cut frame of the calendar window, introduce sharp, shimmering accents against the deep black background. Together with the motif of a meteor shower, these refined details infuse the dial with a sense of dynamic movement and vivid energy.
