HEUER SENATOR
The Heuer Senator GMT was introduced in 1979 and had the same basic layout as the Manhattan, with a digital display at the top and an analog display (hand for the time) at the bottom.
The Senator replaced the hexagonal case of the Manhattan with a rounded, diamond-shaped case. The Senator was offered only as a chronograph with two displays; there was no simple quartz watch. Like the Manhattan, the Senator was part of the Heuer range until 1982.
The Heuer Senator proudly bore the inscription "Swiss Made" on its dial. The chips for the Calibre 107 in the Senator likely came from Heuer Micro-Technik and not from the USA, as IDS filed for bankruptcy in the late 1970s.
History of the Heuer precision watch manufacturer (source: Watchwiki):
Heuer, Edouard
Swiss watchmaker
Edouard Heuer was born in 1840 as the son of a shoemaker in Brügg, Canton Bern.
In 1860, he founded the Heuer watchmaking factory in Saint-Imier in the Swiss Jura. In 1864, he relocated the company to Biel . As early as 1876, he established a branch in London .
Edouard Heuer was the first watchmaker to venture into mass production of chronographs . His basic idea was to make chronographs technically simpler and thus cheaper to manufacture. His primary focus was on simplifying the previously common coupling for the chronograph mechanism. This consisted of numerous components, the manufacturing, finishing, and assembly of which represented a significant cost factor. The so-called oscillating pinion he developed is a no less effective module: a movably mounted shaft with two pinions.
One pinion is in constant mesh with the second wheel of the movement , while the opposite pinion engages the chronograph's center wheel after pressing the start button and briefly pivoting it. This establishes the connection, and the chronograph starts running. Pressing the button again moves the oscillating pinion away from the center wheel, and the chronograph stops. The Parisian Bureau de la Propriété Industrielle granted a patent for this development on May 3 , 1887. This principle is still used today, for example, in the well-known automatic caliber Valjoux 7750 .
From 1880 onwards, Edouard Heuer was the first watchmaker to mass-produce chronographs .
Edouard Heuer died on April 30 , 1892 .
On 1 January 1964, the Heuer watch manufacturer and the Leonidas Watch Factory , Saint-Imier, merged to form Heuer-Leonidas .
In 1985 the company merged with the Techniques d'Avant Garde TAG Group and was renamed TAG Heuer .
