Development History

In 1832, Auguste Agassiz came to work in a small watch shop in a small village in Saint-lmier. , and soon he took over the entire store and changed its name to "Agassiz & Compagnie". Agassiz's nephew Ernest Francillon inherited his business 20 years later.

Francillon had a unique vision. His idea was to concentrate all the mechanical production and assembly of timepieces and other multiple production steps in the same factory to establish a comprehensive production process. So two adjoining pieces of land on the right bank of the River Suze, known locally as Les Longines, were purchased.

In 1867, Francillon established the first Longines watch factory and produced the first key-controlled pocket watch, winning the bronze medal at the Universal Exhibition in Paris, France. The first Longines watch was born.

On May 10, 1880, Longines officially became a registered trademark in Switzerland and is the oldest trademark in the Swiss watchmaking industry.

In 1969, it once again took the lead in producing the world's first quartz watch. Another achievement of the LONGINES watch is the use of the characteristics of quartz vibration to produce a jumping display, becoming the first timepiece to use a liquid crystal display.

At 4:00 pm on May 27, 1889, Longines’ flying-wing hourglass trademark was officially registered in the Product Intellectual Property Office of Bourne, with patent number 2684. Since then, the flying-wing hourglass has become a prominent image of Longines.

In 1904, the Longines Express Monarch was praised by an American Antarctic expedition team. During the 429-day journey, Longines' timepiece could maintain a difference of only four seconds, with amazing accuracy. At the 1912 Federal Games in Basso, the Longines chronograph accurately calculated the speed of 3,500 athletes and once again became the target of praise.

In view of the fact that the timepieces produced at the Longines watch factory are highly accurate and have contributed a lot to navigation research, they have been issued high-level certificates to prove this. Later, in 1964, Longines won the Observatory Champion Award with the world's smallest electronic quartz marine timepiece.

In 1938, Longines produced the second navigation watch, the Siderograph. In 1945, the L22A movement was created, symbolizing the birth of Longines' first fully automatic men's movement.

This series of watches is only 3 mm thick and equipped with waterproof function. Later, in 1983, through continuous research on miniaturized components, Longines launched the L961 "bagUette" small movement specially designed for women's watches, with a thickness of only 1.75 mm.

In 1984, Longines launched the Conquest watch, equipped with a Very High Precision movement, which was a major development for Longines.
