Because the mechanical watch is to rely on power work, not rely on electricity, so the machine is a bit error is normal, and please take the hands of more than 8 hours a day.

The time precision of the mechanical watch is influenced by many factors, in general, it is mainly the following 8 factors: External influence Is from the external effects of watches and clocks, depending on the working environment of the clock. Commonly used measures are: shock proof design, waterproof design, Antimagnetic design, additional protection shell etc.. Friction Friction usually has two positive and negative effects, it has positive on the one hand, such as friction wheel, automatic table between the friction between the spring and the box, On the other hand, friction can lead to the reduction of the transmission efficiency and the friction loss of the parts, thus affecting the timing. Commonly used solutions: to improve the lubrication conditions, According to different requirements, the use of different lubricants; using precious stones bearing or gasket; to improve the gear tooth surface conditions, including the use of scientific conjugate tooth profile and improve the surface finish and so on, But the general tooth surface is not lubricated (in this case, the friction of the oil viscosity may be higher than the friction). Speed needle The speed of the needle is easy to the school at the time of the economic structure, but the theory and practice have confirmed that it would affect the system of isochronism, may also have difference, These timing errors are relatively large, can not be compensated or offset. The solution is: to minimize the distance between the inside and outside of the needle, but the best way is to have no speed needle, By adjusting the balance of inertia to adjust the speed. Escapement Influence of the escapement is the main energy transfer effects on spring balance system in the process of spring balance system only in the case of free vibration, in order to maintain the oscillation frequency, fixed obviously, the escapement energy transfer process will affect the oscillation frequency. The theory shows that the transfer process is close to the balance point, this effect will be reduced. The solution is: using precision escapement, such as claw escapement mechanism, the energy transfer processes occurring near the equilibrium point, impulse the angle is very small, the impact is relatively small, and its one-way transmission at make balance wheel hairspring system has more free space concussion (on this point, the relative error can be reduced by half!). Temperature effect The effect of temperature is mainly manifested in two aspects: first, the working length of temperature change will gossamer, and change the balance of inertia, can directly affect the timing accuracy; secondly, temperature changes will affect the oil viscosity, affect the transmission efficiency, thereby affecting the timing. This can take the following methods: the opening of the bimetal temperature compensation balance spring system; making gossamer and balance is made of special alloy materials, so that the working temperature region (8 degrees 38 degrees) have a certain temperature compensation; the moving speed of needle temperature compensation. Standard lubricating oil. magnetic field The influence of magnetic field the largest hairspring, can change the elastic modulus, the spring deformation under the action of the magnetic field generated additional stress, serious, the magnetic field can lead to gossamer adhesions, seriously affect the travel time. The solution is: using antimagnetic material. Hairspring balance Swing frame hairspring in general, change its focus with the wheel swing angle changes, under the action of gravity, it will produce position error. Balance Balance element directly affects the balance bit difference, static balance wheel component is a basic requirement. If the above factors are more ideal, watch the travel time and more stable, through the dynamic balance of watches, can be integrated to improve the performance of travel time. There is a very special way: When the balance principle is the swing of 220 degrees, all transferred to the balance on the momentum had no effect on the frequency, has been using the balance force mechanism is installed on the escapement wheel, to control the swing in the vicinity of 220, which is regarded as a method.
