Mechanical watch how much error when walking one day normal

Mechanical watch a day how much is normal?

The allowable error range of the mechanical watch is ± 30 seconds / day. The average error of the movement certified by the Hong Kong Observatory ranges from -4 seconds to +6 seconds / day. The specific error depends on the movement used by the watch, not according to The higher the price the smaller the error principle. Automatic mechanical watch power source Wearer wrist swing to generate energy to winding, a fully automatic mechanical watch can last 36 hours of continuous operation: such as to ensure normal daily wear can operate for about 15 hours, such as More than the above time is not wearing or less swinging (wearer less exercise) will cause the watch to stop walking before wearing the watch should be given to the clockwork.

Go wrong when the situation

(1) The accuracy of the watch varies depending on the type of watch movement. Quartz watch is replaced by a quartz vibrator mechanical balance in the table, the use of its correct high-speed oscillation to time, in general, quartz watch high accuracy, the Swiss standard is the monthly error of 15 seconds, some accurate Movement is to achieve annual error within a few seconds.

(2) mechanical watches rely on the internal mechanical devices to control the watch to go evenly and accurately, these mechanical devices will be subject to gravity, the impact of ambient temperature and other errors caused by the general error of mechanical watches is calculated by day, according to the machine The core model and manufacturing quality vary, the general error within 30 seconds each are within the normal range. Some higher precision movement, such as the observatory series can reach about 10 seconds.

Watch suddenly go error increases several common situations

Low battery: If the quartz watch suddenly found to be slow, it is likely caused by insufficient battery power, you can send the watch to a special service point to detect the power.

Insufficient power reserve: You need to check whether the power is sufficient. If the self-winding watch has a small amount of exercise, it may cause insufficient power reserve. You can replenish the power by manual winding, and then observe whether the speed continues.

Watch by the magnetic: If the gossamer mechanical watch is magnetized, the watch is not accurate.

Need to maintain: the lack of oil movement or wear and tear of internal parts may cause travel problems, need to be sent to the designated maintenance point for maintenance services.

Beaten or knocked: watch is very precise, if the impact or beat may cause loose loose parts may also cause travel problems.

In addition to these common conditions, some environmental temperature effects, the impact of the wearer's habits may lead to increased travel error. But you do not need to worry, please send the watch to the designated maintenance point, please professionals to check and adjust the watch can return to normal error range.
