(3) What should I do if the mechanical watch runs slowly?
The reasons for its slowness can be divided into several: 1) insufficient activity and insufficient kinetic energy; 2) the watch is magnetized; 3) the movement sludge is dry.
To solve the situation of insufficient kinetic energy, it is generally necessary to wear it for about 8 hours a day, and the normal and appropriate amount of exercise kinetic energy is required to support walking time. Wearing for 8 hours a day can support 36 hours of walking time.
You can find a compass to diagnose whether the watch is magnetized. Place the compass flat on the desktop, hold the watch to quickly shake it back and forth above the compass at a short distance, and change the direction of the watch several times. As long as the pointer moves, especially if it deflects severely, it can be judged that the watch is magnetized Up. The watch is magnetized, it is best to take it to a repair shop for demagnetization.
If the oil in the watch movement is dry, it will increase the frictional resistance between the parts in the watch, causing damage to the watch parts and unable to operate normally. It is best to get it to a repair shop for treatment.
(4) Do I need to wind the automatic mechanical watch?
A fully automatic mechanical watch is based on the general hand-dial winding watch plus an automatic part. The automatic part includes an automatic tourbillon and an automatic wheel. Under normal circumstances, as long as you wear enough time every day, the automatic rotor can replenish the energy of the clockwork source, so that the automatic watch can run normally. Therefore, the manual winding should be used as little as possible, because the manual winding requires the handle to drive many automatic wheels to rotate together, and the automatic components are very easy to wear and easily cause an increase in maintenance costs.
(5) Will the all-steel strap of mechanical watches appear rusty or fade?
There are many types of stainless steel, and its main components are nickel and chromium, while nickel and chromium are easily corroded by strong acids and alkalis. The sweat discharged from the human body contains hydrochloric acid. When wearing a watch, if you are often exposed to sweat or allow acid, alkali, salt and dirt to accumulate and do not clean up in time, rust spots will gradually appear on the watch strap and black spots will appear on the wrist. Smudge. This is mainly caused by the contact of elements such as nickel contained in stainless steel with human sweat or vinegar, bleach, correction fluid and other chemicals, chemical reagents, cosmetics and other substances. The general approach is to gently scrub the strap with a soft toothbrush dipped in detergent and then dry it with a soft cloth; or go to a brand authorized repair station to clean it with an ultrasonic instrument.
