Hairspring In 1675, Huygens and Robert Hooke invented the spiral balance spring , or the hairspring, designed to control the oscillating speed of the balance wheel .
In his first year, he developed the first iteration of the later iconic Swiss railway clock. The version which was first displayed at the Bahnhofplatz (plaza) adjacent of Zürich Hauptbahnhof (Zürich Central Station) lacked the 'minute' and 'second' hands. [6] Hilfiker would improve upon the design with the addition of a 'minute' hand in 1943.

The very small and light swing wheel, the balanced minute hand, and the small shortened arbors with extra fine pivots, all conduce to the end in view."
