Junghans und Tobler was founded in 1861 by Erhard Junghans and his brother-in-law Jakob Zeller-Tobler. Junghans grew rapidly and was the largest clock manufacturer in the world by 1903. After 100 years, they were producing 20,000 clocks and watches a day. In 1927 the company started producing wristwatches, creating both watches and clocks for both the military and civilian markets. Starting in the 1950s, Max Bill, a Bauhaus-trained designer created many products for Junghans which the company has continued to release. Many of their best-selling items today were based on his designs. Junghans served as the official timekeeper for the 1972 Summer Olympics and in the late 80’s introduced the first radio-controlled table clock.
