Vulcain earned its noblest title in the mid-20th century. In 1947, the “Fabrique de Montres Vulcain” presented the first genuinely operational alarm wristwatch. The idea of incorporating an alarm within a watch was not entirely new. But no watchmaker had ever succeeded in developing a standard-size movement capable of producing a sound powerful enough to awaken its owner. In rising to this challenge, Robert Ditisheim called upon the talents of the finest watchmakers and engineers. After five years of research and development, he presented the famous mechanical hand- wound Cricket calibre, equipped with two barrels, one for the movement and the other for the alarm, emitting a strident sound reminiscent of the shrill chirping of a cricket – hence its name.
