She owned and operated Watson Antique and Classic Cars with her husband, and later served as a director on the Florida Limousine Association of South Florida and served on the Dade County Limousine Advisory Board.

Following its incorporation in 2003, Watson served on the Miami Gardens City Council from 2003 to 2010 and was the vice-mayor from 2007 to 2009.

Watson ran in the Democratic primary on February 8, 2011, and faced former Miami Gardens City Councilwoman Sharon Pritchett and Erhabor Ighodaro.
