Most watches are marked with water, such as 30M, 50M, 100M and so on. There are also part of that is not waterproof. Due to structural needs, and some waterproof and some are not waterproof, not to say not waterproof watch is not a good table, the market a lot more than ten dollars of the plastic sheet can waterproof, can it be a watch it? In addition, is marked waterproof watch, but also refers to the production out of the test is waterproof, but can not guarantee that you do not use a lifetime of water maintenance. For example, many customers bought a Piaget table wearing a bath, and occasionally once or twice did not feel the water, but later found the water several times, into the water is not processed in time, which began to rust inside, go to the store Report the quality of goods is not good, to return. On the other hand, any watch can not be worn to wash the sauna and hot water bath, because the plastic cold shrink, the hot air into the sealed capsule, can not come out, causing the mist is not treated in time, resulting in corrosion, rust, so Watches and watches can only be worn under normal circumstances. In fact, waterproof watch mainly by a small number of rubber ring play a role in a long rubber ring will be aging, there is a gap after the loss of elasticity, it may lead to water, air, so regularly replace the rubber ring to ensure that watches waterproof.

Watches are generally mechanical watches, mechanical watches are on the gear operation, we see how many watches will be marked on the drilling of the watch, the number of drilling is not to say how many diamonds watch, but that the number of gear shaft is used The drilling of the eye, generally replaced by artificial rubies, artificial rubies wear resistance, so the more the table drill hole, the watch relative travel time longer life. But the watch can not use such a hard diamond gear to process materials, it can only be used as a steel wheel axle, watch the smaller the more books, the smaller the wheel, tens of thousands of revolutions per day completely against the drill hole inside the trace of the Oil to reduce wear and tear, once the oil is dry, the axle in dry wear and tear, a few years down, the life of this table also, even though the watches are very high-grade oil, but because the volume is too small, End, like a hair as thin as the axle can wear long? Former table structure is not now complex, and do relatively large, axle is also relatively thick, so some customers say that my table is not to maintain a decade to go, and now the table is getting smaller and smaller, the price is more expensive than before Times, can not hold as previous emotion.
