A fascinating window on a sophisticated high-tech machine. This stylish Irony Chrono Retrograde has a matt black silicon rubber strap with textured relief adding elegance to classic form. The satin-brushed steel case holds a matt steel bezel with embossed screw-top hour markers and engraved black Arabic numerals at 15, 18, 21 and 24 hours. The grooved black dial contrasts red, white and black-on-white indices and highlights enhancing the 30-second, 5-minute, and 60-minute totalizer arcs; the continuous seconds counter is a grooved black dial framed by a black-on-white scale. A minute ring and a tachymeter scale frame the flange. White superlite indices and a Roman numeral XII mark the hours; a black-on-white date window appears at hour 4. Slim tie-shaped hour and minute hands with white superlite highlights mark the time and complement the thin red central second hand of the 30-second counter.
