About the brand: One of America’s foremost manufacturers, Bulova was founded in the late 19th century by Joseph Bulova in Queens, NY. The brand quickly established itself as a maker of high quality watches, and became fully ingrained in American culture - even producing the first ever television commercial. Known for models like their Devil Diver, Sea King, and the later Accutron models, Bulova is something of the un-sung hero of American watchmaking, and a treasure trove for a vintage collector.
