Gold and black switch places in a subtle play of night and day. The anodised shiny aluminium bracelet of this fascinating Irony Chrono Alu shows a central row of gold links framed by black on the 12 o’clock side and black links framed by gold on the 6 o’clock side. The golden anodised shiny aluminium case holds a black aluminium bezel with a white tachometric scale. The high-contrast play of black and gold extends to the sun-brushed gold and black dial with a gold and black minute ring with black or white Arabic numerals (05, 15, 25, 30, 35, 40, 45, 55, 00). A second minute ring with fine black or white indexes and hour markers parallels the first. Large Arabic numerals mark hours 3, 4, 5, 7, 8 and 9 in black and 11, 12, and 1 in white. The chrono and continuous seconds counters have black creusé-effect dials, white numerals and white indexes and white hands; they are labelled MINUTES, DECIMALS and SECONDS. White tuning-fork hour and minute hands and a slim white chrono seconds hand mark the time.
