The Blanc edition trades night for light, a crisp white dial with contrasting subdials and a tachymetre bezel, beneath a domed sapphire crystal in a 316L black PVD case. Full-face lume: the entire dial glows after dark, not just the hands. Miyota automatic. Serial-numbered between the lugs, on the face, and on the caseback. Built to be worn out, not put away.
