Therefore, in addition to changing dry batteries, it is also necessary to do regular maintenance and maintenance of the watch.

Why does the watch stop every hour?

This fault is generally caused by a problem with the core wheel or gear teeth. If it is an old watch, it is mostly related to the wear of the axle eye of the splint. The wear of the axle eye will cause the core wheel to tilt in the splint, which can easily lead to the front end of the minute hand and the dial. The characters or the hands indicating the seconds on the clock rub against each other, while the second hand and thin watches will rub against the inside of the watch glass.

Why does the watch jump to the calendar at noon?

If this happens, it only means that the way you adjust the meter is incorrect. There are 24 hours in a day, but the watch can’t distinguish day or night. The watch calendar is 24 hours, so if you directly adjust to the current time, you may encounter the situation of skipping the calendar at noon.

Then turn the head to the outermost to adjust the time, bring the calendar to the current day, and then adjust to the current time.
