Founded in Taiwan and stationed in Zhuhai, Guangdong Province in 1989, Precision is one of the earliest Taiwan-funded enterprises in China. It used to be the foundry of Casio, Seiko and other brands, and had the largest electronic watch production workshop in China.
 
Although precision has been established for decades, there has never been a technological breakthrough, the design and texture are relatively low-end, and some self-produced digital electronic watches still have residual imitation of Casio watches in appearance.
 
There is no clear series division of precision, low pricing is its biggest advantage, with extremely low pricing to occupy the remaining space of other brands of watches overseas, mainly for the middle and downstream markets.
 
The HRM3 of 199 yuan is already the one with the highest price of accuracy, but the functions are still relatively rich, with a built-in pedometer, heart rate monitoring, and 100m waterproof performance, but the thin shell reduces its durability. The lower price of GJ, only 98 yuan, the function is also simpler and basic, you can set dual time, 24-hour countdown.
 
Overall, precision is not powerful, the main price is affordable, if you just look at the time, ordinary use, its accuracy is enough to meet the basic needs.
