After the First World War, specialists in the construction of raw movements (ebauches) began to form a consortium in a large group where, in the field of chronographs, the lion's share was made by Landeron, which was later joined by Venus and finally Valjoux.
In the 70s, the arrival of quartz, led to the disappearance of almost all the brands that made up the group of ebauches manufacturers, which were gradually absorbed under a single name - ETA swiss technology.
This group alone - belonging today to the Swatch group - represents about 90% of the entire Swiss production of movements, and in its headquarters in Grenchen, since the 80's, has started its own school of watchmaking.
The course includes a theoretical part and a large practical part that culminates at the end of the course with the realization by the student of a complete watch, which normally remains with the student together with the degree obtained.
These watches are marked ETA and are not sold.
However, from time to time, some specimens appears on the market, especially as a result of the lack of interest in the object of the heirs of those who had made that watch and usually kept in memory of an important moment of their professional lives.
This is one of those rare specimens dating from the late 1980s.
