Cyma SA is a Swiss manufacturer of luxury wristwatches, founded by brothers Joseph and Theodore Schwob in 1862.

By 1908, Cyma was advertising the resilience of their timepieces when exposed to electricity, magnetism and varying temperatures.

[1] The company is currently owned by Stelux International, Ltd.[2] a Hong Kong–based holdings firm which invests primarily in fine jewellery and watches, and is overseen by fellow Fédération de L'industrie Horlogère Suisse member Universal Genève.

[3] The Schwob brothers named the company cyma, a Latin word meaning "sprout", and the origin of the French cime ("summit").

On 9 September 2010, Cyma SA and E-Watch organised an event in Yverdon to launch their new brand collection, Myriad.
