The following is the abstract from news entitled "Old Time Not Forgotten by Watch Fans" (dated 18th January 2008) from a news page of Shanghai Municipal Government :
People are queuing up to buy old Shanghai brand watches after recent stories in the media. Dozens of people have been queuing in front of a counter at the entrance to Shanghai No. 2 Watch Factory on Jiaozhou Road, Putuo District.
Three sales assistants were busy serving the customers, mostly elderly citizens. The watches are priced at 40 yuan (US$5.5) to 200 yuan, quite reasonable compared to market prices. But what attracted the elderly citizens most was not the price but the old brand "Baoshihua." Every customer bought at least two watches and there were some who bought as many as six.
A TV program reported on the old brands of watches and bicycles two of necessary articles a family should have for a marriage. "Baoshihua" is one of the most famous watch brands.
Baoshihua" was famous in the 1970s and 1980s. A "Baoshihua" watch cost about 100 yuan, or almost three times the average salary in those days.
Baoshihua from Shanghai Watch Factory No 2 was the first watch in China using standard movement when the movement was just created in early 1970s. The factory code on the movement was SZ-1 and was then changed to this "ZSE". "Z" for Zhongguo (China),  "S" means Shanghai and "E" is for number 2 (2 is ER in pinyin). See this wiki link for more information on standard movement. This movement has a date code of "LC" which indicates that this movement was made in late 1970s or early 1980.
