Watch sellers in Hengshui are mainly concentrated in Jizhou District of Hengshui City, which is the former Jizhou City. There are many brands such as Combas Polaris. As far as I know, there is one company that makes Polaris quartz clocks, no less than five companies that make Polaris perpetual calendars, two companies that make Combas quartz clocks, and there are probably no less than dozens of other brands. They are all relatively small companies. Although they are relatively small, there are a lot of them.
