7 120 62 1 on the back is the key to identification. This is a Shanghai brand 7 120 movement watch. The movement is 19 and the drill is 62 1, which is a production batch.

7 120 movement, as a classic work of Shanghai brand watch factory, is the second-generation self-produced movement after Shanghai 58 1A, 6 1A and 63 1 movement. 1969 was put into production, and the output was extremely high until it was replaced by 8 120 movement in the 1980s.

7 120 is a mechanical medium-sized men's watch. The basic model is that the non-calendar power duration of the big three needles is 40 hours, the winding frequency is 18000 times/hour, and the daily design error is within 45 seconds.

According to the batch number, it is estimated that the watch of the landlord was produced in the mid-1970s, and the exact year cannot be determined.

As for the price, there are still old Shanghai brand watches in stock in the original sales department of Shanghai Watch Factory on Jiaozhou Road in Shanghai or the second sales department of Shanghai Jing 'an Temple. The circle of playing old Shanghai brand watches is not big, the landlord's 7 120 is good, and the market price can be close to 1000 yuan.

Shanghai brand watches were all the rage in the heyday of the country. A quarter of the watches in China are Shanghai brand movements, and their commemorative value is mainly in the spiritual level, just as Beijing brand watches are for Beijingers.

If the landlord likes my answer, please accept the landlord's Happy New Year.
