Mechanical watches do not keep time? Magnetic field is the most easily ignored factor

There have always been watch enthusiasts asking questions about watch timekeeping, which is indeed a problem that bothers many watch wearers and watch enthusiasts. Even though many watch enthusiasts already know that mechanical watches have errors every day, they sometimes find that the daily error is very "unstable", and today we will talk about the biggest factor that affects the inaccuracy of mechanical watches.
First of all, we have to understand that mechanical watches have a reasonable error in the international arena, the general national standard is the daily error shall not exceed 45 seconds, the error can be cumulative;TUDOR Royal M28323-0001 and Switzerland as a major watchmaking country is more rigorous, the permissible error range of mechanical watches is 30 seconds / day;
In addition, there is a more accurate movement, that is, the movement certified by the observatory, the average error range reaches -4 seconds/day to +6 seconds/day.
There are many factors that can lead to inaccurate timekeeping: insufficient power reserve, too long without maintenance, impact, environment, humidity, magnetization, etc..
Today, we are talking about magnetic fields, which are more likely to be encountered on a daily basis.
Magnetic field is an invisible and intangible special substance. Magnetic field comes from the magnetism, magnetism comes from the electric current, simply put, most of the electrically charged items with magnetic field.
How is a mechanical watch affected by magnetism?
There is a component in the movement of a mechanical watch called the hairspring.TUDOR Black Bay 39 M79660-0001 It is also known as the heart of a mechanical watch.
The hairspring is commonly described as a very thin spring, usually made of a blend of steel and other metals, which directly affects the operation of the watch. It has a very small gap, so magnetic fields can easily affect it. The hairspring is originally in a state of proximity to each other but not fitted, when magnetized, the hairspring will be bonded to each other, which will affect the accuracy of the watch, or stop the watch (stopping the watch means the watch stops rotating).
Generally, mechanical watches have anti-magnetic properties when they are purchased. However, they cannot prevent the phenomenon of magnetization for a long time.
Magnetic fields in life
What is the magnetic field we are most likely to come into contact with on a daily basis? That's right, it's cell phones. The cell phone is a strong magnetic field that can magnetize a mechanical watch in a minute.
In addition, a watch repairer with many years of experience once told me that many people who come to demagnetize their watches have one hobby: playing mahjong. That's right! A big invisible killer of mechanical watch, electric mahjong table is the magnetic field we especially want to prevent. In addition, there are all kinds of household appliances: TV, microwave oven, refrigerator, electronic toys and so on, all with large and small magnetic fields.
The anti-magnetic functions of the watch are all set inside the movement. However,TUDOR Glamour Double Date M57103-0005 in addition to the hairspring, other parts will still be affected by the magnetic field, only the main parts to prevent the magnetization does not have much effect, and the number of times of contact with the magnetic field even if the anti-magnetic properties can not resist erosion.
So how do we prevent magnetization? The simplest way to prevent magnetization is to stay away from magnetic fields. Avoid putting the watch next to all kinds of electrical appliances and electrically charged objects is the best prevention.
What to do if you are magnetized
Nowadays, daily electronic products are all over our lives, bringing convenience and at the same time, it is naturally difficult to avoid the magnetization of watches. So how to deal with the magnetization?
The easiest way is to take it back to the after-sale store, which has free demagnetization service. Of course, if you don't mind the trouble, you can buy a demagnetizer for daily use.
