Cyma Watch Co. was founded in Le Locle, Switzerland, in 1862 by the brothers Theodore and Abraham Schwob from La Chaux-de-Fonds. Theodore’s father-in-law was a salesman at Zenith and had some capital to support their enterprise. The company specialized in wrist alarm watches, of which the movements were made in-house. Other companies also used these movements. In 1896, Cyma merged with Frédéric-Henri Sandoz’s Tavannes Watch Co.

Tavannes Watch Co. was founded in 1891 by watchmaker Henri-Frédéric Sandoz from Le Locle and was named after a town. Sandoz obtained several Swiss patents to improve pocket watches.

Tavannes in collaboration with Cyma produced complicated watches using the most modern machines. Around 1905, they began developing pocket chronometers with spiral springs made from a nickel steel alloy by Charles Edouard Guillaume. In 1919, a workshop was set up to manufacture pocket and marine chronometers. They also used the marine chronometer developed by Paul Ditisheim with a central second and exchangeable escapement section. The company achieved many successes with its deck watches in the chronometer competitions of the Neuchâtel Observatory. Even before World War I, they began developing wristwatches. 

In 1969, the companies Cyma, Tavannes Watch Co. and DOXA merged to form Synchron AG, to which the Auréole company has belonged since 1972, but Tavannes Watch Co. has been independent again since 2008 and mainly sells watches in the USA.
