Please have a look at our vintage watches we have constantly listed on Chrono24. Schwöb Frères created the name Cyma as a brand name for Tavannes watches sold through the Schwöb Frères network. Cyma was short and easily pronounced, although being of Swiss-French origin it should be pronounced see-mah, which is not immediately apparent to English speakers. Eventually the name Cyma became much better known than either Tavannes or Schwöb Frères. The arrangement between Tavannes and Schwöb Frères wasn't an amalgamation; the two companies remained separate and watch continued to be made under the Tavannes name. The Tavannes Watch Co. sold watches as well as machinery to other companies, and Schwöb Frères continued to sell other watches under its other brand names. Sometimes it is said that "cyma" means summit in French but this isn't right, the French word for summit is "sommet". It appears that cyma came from the same Latin root as the French word "cime", which is usually translated as top or crown. Cyma-Tavannes was one of the few Swiss companies that up until the 1950s produced most of its own movements. They were a manufacture, not just assemblers who bought movements from other companies and put them into cases with their name on the dial. Cyma-Tavannes finally ceased all in-house production in 1966, the rights to the brand name were purchased by Chronos Holding.
