A balance wheel, or balance, is the ... Robert Hooke first applied a metal spring to the balance in 1658 and Jean de Hautefeuille and Christiaan Huygens improved it ...
Drawing of one of his first balance springs, attached to a balance wheel, by Christiaan Huygens.. There is some dispute as to whether it was invented around 1660 by British physicist Robert Hooke or Dutch scientist Christiaan Huygens, with the likelihood being that Hooke first had the idea, but Huygens built the first functioning watch that used a balance spring.

Hooke's law: the force is proportional to the extension Bourdon tubes are based on Hooke's law. The force created by gas pressure inside the coiled metal tube above unwinds it by an amount proportional to the pressure. The balance wheel at the core of many mechanical clocks and watches depends on Hooke's law. Since the torque generated by the ...

c. 1657: Anchor escapement probably invented by Robert Hooke (1635–1703). [15] c. 1657: Balance spring added to balance wheel by Robert Hooke (1635–1703). [16] [17] c. 1722: Grasshopper escapement invented by John Harrison (1693–1776); Harrison created the H1, H2, H3 & H4 watches (to solve the longitude measurement problem). [18]
One of Hautefeuille's most important achievements was his proposal to use a spiral spring with a balance wheel in place of a pendulum to control a clock. In the 1670s, he was involved in a dispute with Christiaan Huygens , who along with Robert Hooke claimed priority. [ 2 ]
Dials that showed minutes and seconds became common after the increase in accuracy made possible by the balance spring (or hairspring). [112] Invented separately in 1675 by Huygens and Hooke, it enabled the oscillations of the balance wheel to have a fixed frequency. [177]
