In 2015, Klokers designed the emblematic klok-01 based on the circular slide rule invented in 1630..

A time calculation device, the dial is comprised of 3 coplanar graduated discs with a graphical design bringing back fond memories of mathematical calculation instruments. Thanks to its simple styling, the flat-sided case features a distinctive utilitarian look, creating an overall sense of balance and pleasure.

In the centre of the glass, forming a focal point, a yellow disc characterises the overall logic of the design, contributing a bright touch and forcefully emphasising the character of this timeless timepiece. Like a sun bursting with energy and promise, yellow has today become a symbolic colour of this 21st-century.
