In addition to these more playful design references, the HM5 draws on what the 70s meant for the watch industry as well, namely the prevalence of quartz movements and digital displays. You can see here two models that directly contributed to the HM5's conception - the first is a quartz LED watch from Girard-Perregaux (who make the base movement used in the HM5) and the second is an Amida Digitrend, a rudimentary mechanical response to the former.
