Welcome to my Top Swiss Wrist Watches Boutique: Edouard Heuer founded his watch manufacture in 1860 in Saint-Imier. In 1867 the company moved to Bienne, and the series production of chronographs began in 1882, as Heuer receives the first patent for a timer mechanism. In 1887, Heuer invented the oscillating pinion, which is still used today by well-known watch brands. This heritage is reflected in period advertisements, which note that the company is a specialist in simple and complicated chronographs and repeaters, as well as jewels for watches and jewelry. Heuer's sons, Charles-Auguste and Jules-Edouard Heuer, took over the management of the company in 1891, with the name of the firm changing to Edouard Heuer & Co. by 1895. Later, Charles-Edouard Heuer continues the family legacy. In 1911, Heuer presented the first board chronograph for vehicles, called “Time of Trip”. By 1913, the company was advertising the production of bracelet watches with 11 and 13 ligne movements as well as 19 ligne pocket watches. But Heuer's primary product was stopwatches. The company patented and produced the “Micrograph” in 1916, the world's first stopwatch with a precision of 1/100 seconds. And the company was the official timekeeper at the 1920 Olympics in Antwerp. It was also timekeeper in 1924 and 1928, as well as at numerous ski races. In 1933 Heuer developes the first board watches for racing cars and in the same year the legendary stopwatch Autavia. The first use of the familiar pentagonal logo came in the 1930s, with use in advertisements by 1934. Since founded in 1860 by Edouard Heuer, company have been responsible for remarkable watch-making achievements. A company slogan of TAG Heuer is "Don't Crack Under Pressure". The slogan was originally introduced in 1991. TAG Heuer's current lines include Formula One, Aquaracer, Link, Carrera, Monaco, Connected, Autavia, and Heuer Heritage.
