The Gruen Watch Company was formerly one of the largest watch manufacturers in the United States. It was in business from about 1894 to 1958 and was based in Cincinnati, Ohio.
Dietrich Gruen, was born in Germany in 1847. At 15 years of age, he was sent away from home to become a watchmaker's apprentice. Later he worked for three years in Switzerland before going to the U.S.A. In 1874 he took out a patent for a safety pinion (U.S. patent no 157’913) for pocket watches, which prevented damage to the watch movement if the watch's mainspring broke.
