It is customary to call the work hours "running", so during work they can be either late or in a hurry. Each type of watch will have its own reasons for haste.
A mechanical watch can be in a hurry because the balance hair is magnetized. Take the watch to the workshop, there it will be demagnetized. "Haste" can also begin because oil has got on a hair, for example, if you tried to lubricate the mechanism yourself. Electronic watches can be in a hurry because of the pulse generator, which has ceased to withstand the number of pulses per unit of time. To make your digital watch last a long time, take care of it, try to periodically wipe it from dust and do not let the watch mechanism get wet. Take into account the temperature conditions, some models stop working from sharp advances. Treat your watch with care, as the slightest damage affects the accuracy of the readings. Wall electronic clocks powered by the mains may be in a hurry due to the instability of the mains supply. The electronic watch has settings for correcting the movement. If you do not want to send the watch for repair, you can correct its course by setting the necessary values. If the computer clock is in a hurry, there may be several reasons. First, try synchronizing the time over the Internet. If this does not help or the computer is not connected to the Internet, set the clock yourself. Check if the time zone is correct, manually correct the time or change the battery. The computer clock battery is located in the system unit on the motherboard. In appearance, the battery is similar to those in an ordinary electronic watch - a large, round, flat one. If the clock is in a hurry with a new battery, you will have to configure the BIOS. Do not take this job if you do not know where to find the parameters that affect the course of the watch. Remember that self-tuning can lead to irreversible consequences. First, study the instructions for the BIOS of your computer, but it is better to contact the specialists.
