Voutilainen introduces a completely innovative display of the time based on System 1 and System 2 human behaviour, as studied by Nobel Prize-winner Daniel Kahneman. The Vingt-8 ISO breaks with System 1 behaviour, whereby time is read at a glance using a deeply entrenched “code”, and instead elicits System 2 behaviour in which telling the time acquires a deeper, more intellectual dimension. This heightened awareness of time is translated by hour and minute hands which are superimposed on each full hour, and opposed at each half-hour. The angle between the two hands is always the same, whatever the time. The secret lies with the minutes disc that turns with the hour hand so that the minutes hand can mark the elapsed minutes.
