X.      Sudden stop, stopping and timing error

The accuracy of a watch is a comprehensive measurement indicator. People always hope that their watches run accurately. This is possible for quartz watches, but for mechanical watches, their accuracy is determined by the vibration frequency generated by the balance wheel, which is also affected by the internal and external factors such as the position difference, temperature, clockwork torque, magnetic field, etc., and the meticulous adjustment can only reduce errors relatively but cannot completely eliminate such errors.

Q: The timing of the watch is suddenly abnormal. What might be the problems?

a)    Insufficient power reserve: Customers need to be reminded to check if the watch is fully powered. If the watch with self-winding function has a smaller movement, it may cause insufficient power reserve. You can replenish the power by manual winding, and then observe if it continues to run fast or slowly.

b)    Low battery: In case of incorrect timing for a quartz watch, consideration may be given to the battery. If it is discovered the quartz watch suddenly runs slowly, it may be caused by insufficient battery energy. You can send the watch to the repair center to check the power.

c)    Watch magnetized: If the spring of a mechanical watch is magnetized, the watch will be inaccurate, and it needs to be sent to the repair center for degaussing.

d)    Maintenance required: Lack of oil in the movement or aging of internal parts may cause timing problems and require maintenance services.

e)    Suffering from falling or impact: The watch is a precision instrument. If it is hit or beat, it may cause loose inner parts and timing problems.

f)    In addition to the above common conditions, some of the effects of ambient temperature and the wearer’s habits may also lead to inaccurate timing. But don’t worry, please send the watch to a designated repair center and ask the professional to check and adjust to return the watch to its normal error range.

Q: Why is the mechanical watch suddenly appearing to go faster?

A: The phenomenon that the watch suddenly runs for more than ten minutes to several hours ahead is generally caused by:

1.    The watch is placed next to an appliance producing magnetic field or a magnetic object;

2.    After any water enters the watch, the balance spring is stained with water;

3.    The hairspring is contaminated by foreign bodies;

The allowable error of a typical mechanical watch is 30 seconds per day, and that of the quartz watch is + / - 15 seconds per month. The specific error depends on the movement used in the watch.

If inaccurate timing is caused by the above reasons, you need to go to a SAGA designated repair outlet to degauss or clean and maintain the hairspring.

Q: Why does a mechanical watch suddenly stop after is bought just a few months? 

•      A: There are many reasons such as: impact, falling, magnetization or insufficient winding, and so on. It needs to be determined by professional and technical personnel with the professional testing equipment.

Q: Why is the battery powered out not long after a quartz watch is bought?

A: This is because the battery of the watch has been loaded before leaving the factory, which is mainly used to check the function and performance of the watch, and to monitor. When you purchase a watch, a certain amount of electricity in the battery has already be consumed, so we will stipulate that the battery will be replaced free of charge within one year.

Q: Why is it that my quartz watch runs inaccurately when it is worn, but normally when it is placed on a table?

A: An important reason why the quartz watch runs inaccurately is that it has been magnetized. If a quartz watch is magnetized, it will be disturbed in the magnetic field environment, leading to inaccurate timing. After leaving the magnetic field environment, the interference naturally disappears and the watch returns to normal operation. When it is worn, it is possible to be exposed to a strong magnetic field environment. For example, the computer mainframe, the display, the magnetic car door, the shoulder bag’s magnetic buckle, etc., which leads to inaccurate timing. When you lay it on the table, it is away from the magnetic field, and will run normally. Of course, it may also be sent to professional repairman for testing on a professional instrument.
