(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.
A compass is not a conclusive diagnosis of magnetism, and the steel case can affect its needle. Do not shake the watch to test it. If timekeeping changes substantially, have the movement checked by a qualified watchmaker.
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?
An automatic mechanical watch uses a winding rotor (oscillating weight) and a gear train to wind the mainspring as your wrist moves. The rotor is not a tourbillon. Whether daily wear provides enough power depends on the movement and your activity. If your movement supports manual winding, wind it as instructed by the manufacturer when needed, especially after the watch has stopped. Some automatic movements do not support manual winding, so check the instructions for your specific model. Follow the model-specific instructions for winding direction and the recommended number of crown turns, and do not force the crown.
(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.
