2. If you think the first item is too troublesome and you are not allergic to paint, you can consider asking a watch shop professional to help you spray a layer of transparent bright paint on your watch, which can reduce skin contact without affecting the beauty of your watch. Of course, it's not an expensive watch.
3. If it is a non-metallic strap and back cover, then the best thing is to change the material directly.
4. If you wear it for a long time and sweat rusts the lid, which leads to allergies, you can consider changing hands or putting it in your underwear pocket with a watch chain.
Watch introduction:
The manufacture and production of watches are based on a simple and witty invention, that is, "clockwork", which can tighten and store energy, slowly release energy to push the running devices and hands in the watch and achieve the function of displaying time. This spring device in the watch is called the main spring.
(Main power). Watch structure A watch consists of a meter head and a strap (clasp). Among them, the parts of the rice head include: movement, case, bottom cover, mirror, characters (often called dial), hands, handles (also called push) and order (required by some tables).
The working principle of watches, watches are precision instruments used to display time. The principle of this instrument is to use a vibration system with constant period and continuous vibration as the standard. If we know the time (vibration period) required for a vibration system to complete a complete watch vibration and calculate the vibration times, then the time after so many vibrations is equal to the vibration period multiplied by the vibration times. That is, time = vibration period × vibration times.
The mechanical watch with balance shaft hairspring adopts balance spring as vibration system. The balance wheel 1 is fixed on the balance shaft 2, and the upper and lower journals of the balance shaft are sleeved in the bearing and can rotate around the bearing. One end of the hairspring part 3 is fixed on the swing shaft, and the other end is fixed on the splint. Due to the elastic deformation of the hairspring, the motion of the balance wheel changes from rotation to reciprocating motion. The balance hairspring system is affected by bearing friction, air resistance and internal friction of hairspring, and the swing amplitude (amplitude) will gradually decay until it stops. In order to make it vibrate continuously without attenuation, it is necessary to replenish energy to the hairspring system regularly, that is to say, there must be an energy device in the watch. The periodic energy supplement of vibration system is realized by a special mechanism & escapement mechanism. The escapement mechanism is also used to calculate the vibration time of the hairspring system. Therefore, the hairspring system and escapement mechanism are the key devices of mechanical watches.
Brief introduction of skin allergy:
Skin allergy is also called sensitive skin. The main features are thin skin and allergies. From a medical point of view, skin allergy mainly refers to the abnormal phenomena such as redness, itching, peeling and allergic dermatitis when the skin is stimulated by various cosmetics, chemicals, pollen, certain foods and polluted air. Sensitive skin can be said to be an unstable skin, which is always on high alert. People who are allergic to sensitive skin usually have skin allergies, dry skin, peeling, redness, greasy skin, sensitive tingling and so on.
