　　手表的防水性能主要依靠表镜、后盖、表冠等处的防水胶圈，并采用螺旋式表冠，从而达到相应的防水标准。关于手表防水方面的认识，不少人还存在着误区，有些人认为我的手表防水可以达到100米甚至300米之多，所以就戴着自己的爱表去洗澡去桑拿。其实这样的做法是完全错误的。下面由精时恒达修表师傅为大家讲解以后你就会明白了。

　　“手表防水”是认知误区

　　一、 防水标准：

　　(1)30米：日常生活防水，防水溅。可以戴着洗手、洗脸。

　　(2)50米：日常生活防水加强性，可以用少量的冷水去冲洗，不能浸泡在水中。

　　(3)100米：潜浮标准，可以在泳池或者海水表面使用。

　　(4)200米以上：潜水表，可以在戴水下呼吸器具的深度使用(要根据潜水深度来选择配戴手表的防水标准)

　　(5)防汗(SWEAT-RESISTANT)，不防水(表后盖勿标识)。

　　(6)一般性防水(WATER-RESISTANT)，30米防水(30M、3ATM、3BAR)，50 米防水(50M、5ATM、5BAR)。

　　(7)潜水表100米防水，200米防水，300米防水等。

　　二、关于手表的防水性能，国家标准和国际标准都有明确的规定：凡是标明防水的手表，**要耐受2个大气压，即20米水深处不进水。30米防水表示手表可以耐受3个大气压，依此类推。此标准的前提是在进行测试的时候是在实验室条件下：温度保持在20-25摄氏度，且手表和水都呈静止状态。在这种情况下手表如果能够防水，即是合格的。

　　三、有些人认为我的手表防水可以达到100米甚至300米之多，所以就戴着自己的爱表去洗澡去桑拿。其实这样的做法是完全错误的，因为手表本身并不是一个**密封的壳子，也就是说防水不一定防水蒸气，我们都知道水蒸气是混合在空气中的，之所以能飘在空气里是因为水蒸气的分子结构非常小。而手表的密封是靠防水橡圈赌注底盖和表壳之间的缝隙，如温差变化大时大气压力会把带有大量水气的空气挤入手表中，并且水还会老化橡胶，使其性能下降从而失去防水功能。

　　四、在说说如果手表进水会对手表带来哪些伤害。首先大家都知道石英表和电子表是由电阻电容和电池等元器件组成，水本身是良导体，电子会在水中“流动”进水量大的话短期内会烧毁石英基板，进水量少的话短期内可能不会有问题。但是长期下来水会腐蚀电路板造成**性伤害。机械表进水会氧化游丝齿轮等其它部件，造成精度下降甚至无法使用。温差过大如蒸气房内，会使手表部件变型，阻容器件改变电器性。从而造成手表停走或精度下降。

　　五、从上述可以看出无论你的表有怎样高的工艺和怎样强的防水标准，都不要去尝试洗澡(冷水澡除外)或桑拿。如果你的表已经进水，请用**短时间将表送去专业维修点进行维修。

　　Watch waterproof performance mainly depends on the table mirror, waterproof apron, crown cover etc., and adopts a spiral type crown, so as to achieve the corresponding waterproof standard. On the understanding of the waterproof watch, many people still have a misunderstanding, some people think that my watch waterproof can reach 100 meters or even more than 300 meters, so they wear their own love to take a bath to the sauna. In fact, this approach is completely wrong. The following table by the Swiss Hengxiu master as we explain later you will understand.

　　"Watch waterproof" is a cognitive error

　　First, waterproof standard:

　　(1) 30 meters: daily life waterproof, waterproof splash. You can wear your hands, wash your face.

　　(2) 50 meters: the daily life of waterproof reinforced, you can use a small amount of cold water to wash, can not be soaked in water.

　　(3) 100 meters: floating standard, can be used in swimming pools or sea surface.

　　(4) more than 200 meters: diving watch, can be used in the depth of the use of underwater breathing apparatus (to choose according to the depth of the water to choose to wear watches waterproof standard)

　　(5) anti sweat (SWEAT-RESISTANT), not waterproof (do not label the back cover).

　　(50) general waterproof (WATER-RESISTANT), 30 meters waterproof (30M, 3ATM, 3BAR), 6 meters waterproof (50M, 5ATM, 5BAR).

　　(7) diving table 100 meters waterproof, 200 meters waterproof, 300 meters waterproof, etc..

　　Two, on the watch's waterproof performance, national standards and international standards are clearly defined: those who are marked with waterproof watch, the minimum to withstand 2 atmospheric pressure, that is, 20 meters deep water without water. 30 meters waterproof said the watch can withstand 3 atmospheres, and so on. This standard is based on the premise that the test is in the laboratory conditions: the temperature is maintained at 20-25 degrees Celsius, and the watch and the water is static. In this case, if the watch can be waterproof, that is qualified.

　　Three, some people think that my watch is waterproof to 100 meters or even more than 300 meters, so they wear their own love to take a bath to the sauna. In fact, this approach is completely wrong, because the watch itself is not an absolute sealing shell, that is not necessarily waterproof waterproof steam, we all know that the water vapor is mixed in the air, can float in the air because of the molecular structure of water vapor is very small. And watch the gap between the seal is on the waterproof rubber ring bet bottom cover and case, such as the temperature changes when the atmospheric pressure pushes the air into the water with a large number of watches, and water will make the performance of rubber aging, thus losing the waterproof function.

　　Four, said that if the watch is water will bring harm to watch. First, we all know quartz watches and electronic table is composed of resistors and capacitors and batteries and other components, the water itself is a good conductor, electronic big inflow in the water flow will burn the quartz substrate in the short term, the amount of water less then may not have problems in the short term. But long-term down the water will cause permanent damage to the circuit board. Mechanical water oxidation and other components caused by the gossamer gear, can't even use the accuracy. The temperature is too large, such as the steam room, will make the watch parts, resistance and capacitance devices to change the electrical properties. Thus causing the watch to stop or decrease the accuracy.

　　Five, from the above can be seen regardless of your watch how high technology and how strong waterproof standard, do not try to take a bath (except for cold bath) or sauna. If your watch has been flooded, please send your watch to the professional service point for maintenance.
