Tag Heuer also created quartz watches in 1975 when they launched the Chronosplit, the world’s first quartz wrist-chronograph with LCD display and accurate to 1/10th of a second. The Monaco and the Calibre 11, the first automatic chronograph movement with micro-rotor, were both released the same year, in 1969. On February 20th 1962, the astronaut John Glenn wore a Heuer stopwatch in space aboard the Mercury mission Friendship 7. In 1949 Tag Heuer presented the Mareographe, the first wrist-chronograph with a tide indicator. In 1933 Tag Heuer introduced the Autavia, a stopwatch for aircraft instrument panels. These stopwatches were used as timekeeping instruments for the Olympic Games in Antwerp, Paris and Amsterdam.

In 1916 Charles-Auguste Heuer unveiled the first stopwatches with 1/100th of a second accuracy and later, the first stopwatches with 1/50th of a second. Only in 1985 did the brand become Tag Heuer. At that time, Edouard Heuer had a watchmaking shop in the Swiss Jura under the name “Edouard Heuer”.
