Description
This model is an example of the most important type of watch escapement - the balance wheel mechanism. The impulse from the escape wheel is transferred to the balance by two levers. This type of escapement was used by the Dutch scientist Christiaan Huygens (1629-1693) in his balance spring watch of 1675.
