The History of Cyma Tavannes Watch Company Cyma is a watch brand that has long been associated with accuracy. Even the name Cyma, derived from the French cime for top or summit indicated the aims of the company, that of reaching the pinnacle of of accuracy. Cyma can trace its routes back to the Schwob brothers Joseph and Theodore, who initially established cyma in 1862 as a watch manufacturer that assembled watches from components derived from multiple Swiss sources. At about the same time 1871, Henri Sandoz established Sandoz & Cie in Le Locle. However Sandoz moved to Tavannes in 1891, just North of Biel where he focused on the manufacture of highly complex repeaters and chronographs. Soon after this move Sandoz formed a developed a business relationship with the Schwob brothers and Cyma was officially registered in 1903. Sandoz used the most modern of manufacturing processes and produced very high quality time-pieces, trademarked as Tavannes, Cyma and Cyma Tavannes. The quality of the product allowed Tavannes/Cyma to develop into one of the largest Swiss watch manufacturers by 1910. Even basic models were very accurate and many were consequently sold as officially tested chronometers. By the 1920s, Cyma had followed a growing trend to standardize watch part manufacture, but typical of the company, it wasn’t enough to just produce parts that were interchangeable, they had to be precision made to ensure long term accuracy.
