Gruen Precision Swiss 17 Jewels Manual Wind Vintage 1960's Mens Watch 31mm 36 mm The face of the ringThe Gruen Watch Company is a famous American watchmaker, founded in 1894 in Cincinnati. It constructed the Timehill Building, featured in much of its early advertising. The company later opened a factory in Biel Switzerland. The Gruen philosophy was to adhere to the spirit of the old guilds. Gruen made beautiful ladies and gents watches with very high quality movements, often using the same as those used by Rolex in the early part of the 20th century.
