Why will appear sometimes steel watchcase?
By the general conditions of all-steel table and will not rust, but everything is relative. Many different types of stainless steel. Emissions from human sweat contains hydrochloric acid ingredients, table wear at the hands of, if the long-term erosion by sweat or allow the accumulation of acid-base instead of salt, remove dirt, watchcase will gradually appear, especially low back cavity prone. Therefore, should pay attention to watch the normal maintenance, always wipe up dust watchcase sediments, sweat and so on. In addition, should try to avoid strong acid, alkali and other occasions to wear under the table to operate, so that steel will not appear watchcase.

Watch as a high-precision timing equipment, and art jewelry, proper use and maintenance of essential and be able to extend the service life of precision watches and pieces of the beautiful appearance to make it more convenient for your work and life.

(2) Table mirror:
Table Mirror watches can be divided into the synthesis of the basic, mineral glass, sapphire crystal glass. The wear resistance of synthetic less scratch-prone, but highly resistant to impact force; sapphire crystal glass and wear engage in, but brittle material than the fear of violent collision; mineral qualities of glass in between. Even if the wear-resistant sapphire crystal glass should also pay attention to objects of other diamonds, grindstone, sandpaper, nail file, stone flower Net noodle, concrete walls, etc. contained impurities, so as not to scratch the surface.
2, about waterproof watches

4, about mechanical watches
2-3 years should be at one times maintenance movement, such as cleaning come on. If not wearing a long-term should also be regularly tighten, so that machine-chip rotation period.
