Do You Know These Watch Tips?

Is it true that automatic mechanical watches don't need to be wound up as long as they are worn on the wrist?

This is a misconception. Automatic mechanical watches can rotate the automatic rotor by swinging of the arm, which drives the mainspring to generate kinetic energy. However, depending on your job nature or lifestyle habits, the kinetic energy generated may not be enough to sustain the energy required for the operation of the watch. The watch may stop running or have enough energy to run but not enough energy to store. This means that when you take off the watch, it will stop running after a while, and you need to manually wind it up to store energy.

Recommendation by custom watch factory: Automatic mechanical watches should be wound up at least once every two weeks to store energy.

Does a waterproof watch mean it will not enter the water?

The waterproof level of watches is divided into 30 meters, 50 meters, 100 meters, and 200 meters. The waterproof performance of watches with different levels is different. However, regardless of the waterproof level of the watch, it is not recommended to wear it when taking hot baths or in saunas. Water molecules have much stronger permeability under higher temperatures. Also, due to thermal expansion and contraction, some OEM watch parts of the watch may expand, and gaps may increase, leading to water entering. Additionally, you cannot adjust the watch crown in underwater or humid environments.

What should you do if your watch enters the water?

For slight water intrusion, place the custom mechanical watch face down and the bottom cover facing outward, and wear it in reverse on your wrist. The steam will dissipate in two hours. If the water intrusion is severe, please contact the merchant immediately for assistance.

Why can't I wind up my automatic mechanical watch completely?

This is basic knowledge. Anyone with a little understanding should know that after winding up an automatic watch manually until it is completely wound, you can still continue to wind it up without damaging the mainspring.

The reason is that when the mainspring is tightly wound, the automatic winding mechanism still works and continues to wind the mainspring, preventing it from being damaged.

Principle: The mainspring of the automatic watch is a special spring with a short auxiliary spring at its outer end. After this type of mainspring is installed in the barrel, its outermost circle is between the barrel wall and the auxiliary spring. Due to the action of the auxiliary spring, there is a certain pressure difference between the end of the mainspring and the barrel wall. When there is a tendency for relative sliding between the end of the mainspring and the barrel wall, a certain frictional force will be generated. This frictional torque is slightly greater than the maximum winding torque of the mainspring. Therefore, the mainspring can continue to be wounded before it is fully wounded, but after it is fully wounded, it will slip along the barrel wall. In this way, the mainspring will not snap, and the automatic mechanism will not be damaged.

The slipping torque of the auxiliary spring has a relatively large influence on the torque output of the mechanical watch train, which directly affects the height of the swing amplitude. To stabilize the slipping torque, many mechanical watches also have grooves on the inner wall of the barrel.
