In 1887 the 22 year old Georges Emile Eberhard founded the manufacture d'Horlogerie Eberhard & Co in La Chaux-de-Fonds. The company launched the first chronograph in 1919 with a hinged case and articulated lugs on a strap, the chronograph operated with a single button. In 1935 the company presented the two button chronograph, allowing the wearer to start and stop the chronograph without setting it back to zero. Only four years later Eberhard & Co introduced its first chronograph with a rattrapante. 

On this watch the lower pusher works as a lock mechanism, the start and stop function is integrated in the crown. The split-seconds mechanism is controlled by the upper pusher.
