ETA C07.111

History: This movement is officially called the ETA C07.111. It is based on the ETA 2824-2. To achieve the large power reserve, it has 2 less jewels, some new parts that exhibit less friction, and the bph has been reduced from 28,800 to 21,600.

Tissot worked with ETA for the research and development of the Powermatic 80 movement. The ETA/Tissot Powermatic 80 Automatic caliber has 80 hours of power reserve. This is achieved through a new construction concept that integrates a new spring barrel. The movement is extremely precise and robust by means of augmentations to the regulator system. ETA removed the index-assembly system and replaced it with an innovative escapement that has no regulator. The rate is set at the factory with a laser, making the manual rate adjustments normally required by a mechanical watch unnecessary. The movement is entirely made of ARCAP, an alloy of copper, nickel and zinc with exceptional anti-magnetic qualities.

Manufacturer: ETA SA Manufacture Horlogère Suisse (commonly called ETA) is the best-known Swiss ebauche movement manufacturer. Part of the Swatch Group, ETA traces its lineage to 1793, though the name dates only to 1932.

ETA emerged as a holding company for the majority of Swiss watch movement production in the 20th century. As such, it can trace its roots to some of the earliest factories in Switzerland. In 1793, Isaac and David Benguerel, Julien and Francois Humbert-Droz founded the first factory for ebauche movements, Fabrique d'Horlogerie de Fontainemelon (FHF), in Fontainemelon, Canton of Neuchâtel. FHF began industrial production of watch movements in 1816, and this date is another appropriate beginning point for ETA, since FHF was absorbed into the company in 1982.

The true beginning of ETA is 1856, when Urs Schild and Dr. Joseph Girard founded an ebauche factory in Grenchen. This company would become Eterna, which was split 76 years later to become ETA. Also in Grenchen, in 1896, Adolf Schild founds the ebauche company A. Schild (AS), where the first cylinder and pin lever movements are produced.

On 27 December 1926, A. Schild AG (AS or ASSA) and Adolphe Michel SA (AMSA) of Grenchen and Fabrique d' Horlogerie de Fontainemelon (FHF) of Fontainemelon join together to form Ebauches SA. This holding company is intended to bring order to the chaotic watch movement manufacturing industry, and it expands rapidly. Soon, Ebauches SA is the largest producer of watch movement blanks in Switzerland.
