Spectral perspectives light up the night. The black structured silicon strap of this excellent Irony Chrono Alu features an array of coloured microinjection dots ranging from purple through red and orange to yellow. The strap holds a silver aluminium case with stainless steel 316L crown and push buttons and a silver aluminium bezel with a black tachymeter scale. Surrounding the sun-brushed silver dial is a flange with a minute ring showing white indices on black and multiple colours. Similarly varied colour spectrums ring the black chrono and continuous seconds counter subdials, which show white hands. Large black Arabic skeleton numerals with white infills indicate hours 4, 8 and 12, and a white-on-black date window at hour 3 marks the time. Black hour and minute hands with highlights in a spectral range of superlite colours, along with a bright green central chrono seconds hand, mark the time.
