Launched on Kickstarter before its brother KLOK-02, the Klokers KLOK-01 pays homage to the slide rules, a once ubiquitous calculating instrument. Before the advent of cheap pocket calculators, slide rules were the fastest method for working out complex calculations. The Klokers Klok-01 display is a graphical representation of a slide rule using three rotating concentric rings to display the time along a vertical red line. The rings — one each for hours, minutes, and seconds — rotate at different speeds, making the whole dial a symphony of motion.

An integrated magnifying lens in the crystal ensures high legibility when reading the time. The 44 mm case is fabricated from a modern composite of stainless steel and polymers for maximum strength and comfort.

Klokers KLOK-01 is available on Kickstarter in yellow, grey, and indigo for € 349 (about $397 USD).
