Watkins Electric Music (WEM) is a British company founded in 1949 by Charlie Watkins and his brother Reg. WEM started as a record shop in Tooting Market, London, later moving to a small shop in Balham where the brothers began selling guitars and accordions.

From the 1950s to the 1970s WEM manufactured guitars, amplifiers, PA systems and the famous CopiCat tape loop delay. The company still existed in  2011 and was still run by Charlie Watkins at that time, focusing on accordions and a new version of the CopiCat. Charlie Watkins died in 2014.

Charlie Watkins was the amp expert, while brothers Sid and Reg made the guitars in the Watkins factory in Chertsey. In 1969 they decided to separate the product lines into separate companies, the guitars were made under the Wilson brandname, Wilson being their mother's maiden name.
