The allowable error range of quartz meter with quartz core is (+15 seconds/month). The running time of quartz watches is driven by battery energy. The battery life of quartz watches varies from 12 to 24 months depending on the movement of the watches. If your watch has a weak current display function, when the battery is almost exhausted, the second hand will beat every four seconds. If this happens, you should replace the battery immediately. Overdue time may cause damage to the machine parts. If it is found that the time is slow, it may be caused by insufficient power, it can be checked at the authorized maintenance center.

Batteries need to be replaced. The operation of batteries is about every two years for women and every four years for men. In Swiss watches, all battery changes are in line with the specifications of individual brands, and include hydraulic tests and replacement seals to ensure water resistance. In Swiss watches, all repairs are guaranteed for one year.
The automatic machine core is relative to the hand winding machine watch. The automatic machine core watch is the automatic winding watch. It uses the power generated by the swing of the automatic disc at the bottom of the machine core to drive the winding to generate energy, but the relative thickness of the watch itself will be thicker than that of the ordinary hand winding watch.
General mechanical watches have a helix. When people chord their watches, the helix is tightened at the same time. When the helix is loosened, it starts to drive the core to move. The automatic machine core is a kind of automatic parts: automatic gyroscope and automatic wheel, which are added to the chain list by hand. The winding can be tightened by turning the automatic gyro in any direction.
Watches have automatic lifting designs that can be worn continuously. In order to ensure the best performance and accurate timing, it is recommended that you have your mechanical watch, standard service every two years.
