The simplicity and the color contrast dominate this Irony Chrono, with the textured black rubber strap and matt aluminum case setting off the tachymetre scale in black on the aluminum bezel and the black dial. Three sub dials with red hands and white numerals on black dials catch the eye. Bold white hour, fine minute markers and Arabic numerals at the minutes 5, 15, 25, 35, 40, 45 and 55 ring the chrono-zone, and a bold date white-on-black window is positioned at 4. Black hour and minute hands with white tips and a white seconds hand mark the time.
