Due to structural requirements, most watches on the market are marked waterproof, but some are not waterproof, to distinguish whether the watch is waterproof or unscientific classification, but no matter whether the watch is marked waterproof, as a Love table, you still need to do regular maintenance for the watch to extend the life of the watch movement. Most watch are marked waterproof, such as 30M, 50M, 100M and so on. There are also some notices that are not waterproof. Due to structural needs, some waterproof and not waterproof, not to say that waterproof watch is not a good table, the market a lot of ten dollars of plastic table can be waterproof, can it be regarded as a watch? In fact, the watch waterproof mainly by a small number of rubber ring role, a long rubber ring will be aging, there is a gap after the loss of elasticity, it may lead to water, air intake, so to regularly replace the seal rubber ring to ensure the watch waterproof. First, the watch seal problem In addition, that is marked waterproof watch, also means produced when tested is waterproof, but can not guarantee that you do not care to use life is waterproof. For example, many customers bought the count table wearing a table bath, and occasionally once or twice did not feel the water, but after a few found that the water into the water is not timely treatment, over time, rusty inside, go to the store Poor product quality, to return. On the other hand, any watch can not be worn to wash the sauna and hot bath, because the adhesive shrinkage, the hot air into the sealed capsule, can not come out, resulting in the fog is not handled in time, causing corrosion and rust, so The watch can only be worn under normal conditions. Second, the problem of mechanical operation Watches are generally mechanical watches, mechanical watches are on the gear operation, we see how many watches will be marked on the watch, this number of diamonds is not to say how many diamond watch, but shows how many gear shaft is used Bored, the general use of artificial diamond instead, due to wear-resistant artificial diamond, so watch the more drilling, watch relative to go live longer. However, the watch's gear can not be processed with such a hard material as diamond, it can only be used as steel axles, the smaller the watch more books, the smaller the wheel shaft, the number of revolutions per day tens of thousands of revolutions rely entirely on the drill inside the trace Oil to reduce wear and tear, once the oil dry, the axle is dry wear and tear, a few years down, the life of the table also arrived, although the watch oil is very high, but because the amount is too small, a few years will certainly be volatile End, how long can a worn axle be worn like a hair? The previous table structure is not complicated now, and do relatively large, the axle is relatively thick, so some customers say my watch is not maintained in ten years are gone, and now the table is getting smaller and smaller, the price is more expensive than before Times, can not hold as the previous feeling. Third, the appearance of maintenance The general appearance of the watch with K gold, K platinum, animal skin material. K gold Although the main raw material is gold, but the man's sweat is acidic plus air corrosion over time is far from new, beautiful, which requires frequent cleaning and polishing, the watch to maintain a new. If it is K platinum, silver outer wear over time for a long time, which exposed the gold, there is no less white, so also need regular maintenance of white, in order to maintain Changxin. Needless to say, leather strap, sweat stains will lead to premature hardening of the skin cracking, normal maintenance should avoid sweat and rainy period wearing leather watch. If the watch is made of steel shell belt, polished often refurbished, better reflect its value. So for the watch, the quality of maintenance will have a direct impact on its value.
