Book excerpt: In the 1960s, Bulova introduced tuning fork technology into their Accutron watches. Instead of a balance wheel, a tuning fork controls the watch timing mechanism. This improves timekeeping accuracy without daily watch winding.Millions of Bulova Accutron watch styles were sold from 1960 to 1977 through retail channels. A watch style defines the watch including the movement, case, dial and band.This Guide is the first comprehensive book on the over 1,100 styles of Bulova Accutron watches. Each watch style in this book is pictured and may include the original sell price and Bulova description.This authoritative work also documents Accutron competitor watches such as: Citizen Hisonic, Cosmotron, Universal Geneve, Russian Slava, Esa F300, Swiss Beta 21, Omega Megasonic and Longines Ultra-quartz.
