1In September, 1955, Shanghai Light Industry Bureau organized 58 masters in Shanghai watch industry to make 18 models of fine horse mechanical watches by hand, which should be regarded as the originator of China watches. 1958, Shanghai Watch Factory officially established a factory and produced the first batch of Shanghai brand watches, rewriting the history that China people can only repair watches but can't make them. This is the apple A58 1 in the eyes of collectors.

A58 1 is the first generation of fine horse watches made in China. It is a 17 drill, three needles long, with an outer diameter of 25.6 mm, and the balance wheel is equipped with a 14 screw. The quality is close to Swiss Polaroid watches. It can walk continuously for more than 36 hours, and the daily difference is less than 1 min.

After A58 1 was put into the market, Premier Zhou Enlai bought one and used it for a long time. At that time, it was a canvas strap. During his overseas visit to Africa, he also showed the Guinean President his clothes, shoes and watches, which were made in China, to illustrate the necessity and possibility of self-reliance. This is only shown in the National Museum of China.

In July 1958, 1, Shanghai brand watches were listed in the third department store in Shanghai, and customers queued to buy them. Xinmin Evening News also sent reports and pictures. At the end of 1960s, the technicians of the watch factory chose a word "Shang" and a word "Hai" from their handwriting to spell a hairstyle. The trademark "Shanghai" has been used to this day.

There is an A58 1. On the surface, the word "Shanghai" is an art form. 2.200 yuan. Deal. Later, it was appraised by Zhou Baoxing, a Shanghai brand watch collector, and it was considered to be worth the money. He also told us that A58 1 is actually a movement, which is the core component of watches, and there are more than 70 styles of watches produced by it.

Later, many new people appeared in the ranks of Shanghai brand watches, such as SS1A. From 1964 to 1966, this movement is improved on the basis of summarizing the completely designed escapement and speed regulating mechanism, vigorously adjusting and improving the shape of the watch plate, and summarizing A58 1 movement. The travel time accuracy meets the assessment requirements of the first-class mechanical watch standard of the Ministry of Light Industry. It is said that by 6546.
