ASUAG had been founded in 1931, with the assistance of the Swiss government and the Swiss banks, to combat the severe economic crisis and ensuing unemployment by means of refinancing (thus eliminate the deadly "dumping for survival" murderous competition within the still somewhat "cottage industry"-like status of a majority of the movements and parts thereof supplying companies) and complementary research and development programs in their respective companies.
Its mandate was to maintain, improve and develop the Swiss watch industry. 
ASUAG also expanded gradually through the purchase of
- further Ebauches manufactures (movement blanks)
- movement parts manufactures (e.g. balance wheels, assortments, rubies) and
- a number of assemblers and manufacturers of complete watches, that were subsequently brought together under the subsidiary “GWC General Watch Co. Ltd.” ] "Manufacturing time", by Amy Glasmeier]:
Affiliated watch brands and companies
- A. Reymond S.A. (Brands: Arsa, Damas and Hoga )
- Atlantic S.A
Merger with SSIH into SMH
However, it proved difficult to implement a common industrial policy for the subsidiaries concerned. Following repeated crises in the Swiss watch industry, by the 1970s, ASUAG (SSIH as well) were once again in trouble. Foreign competition, in particular the Japanese watch industry, with its mass production of cheap new electronic products and new technology, was rapidly establishing a strong foothold in the market.
Eventually, both ASUAG and SSIH faced liquidation: thus, in 1983, “GWC General Watch Co.”, and its affiliated watch brands and factories, were merged with its parent company ASUAG, together with SSIH, into what has now become the Swatch Group, (see:  Swatch Group Official History Profile), under the patronage of the Swiss Banks that were at the time financially involved.
Some companies had however beforehand made themselves again independent or having been sold off, e.g.
