The so-called waterproof 30 meters of the watch is tested in a constant temperature and static state in the laboratory. The so-called 30 meters is actually pressurized in a pressurized test cylinder, and 3 Bass is also 3 atmospheres. The pressure of approx. 30 meters water depth is not really 30 meters dive! ! ! In fact, when people wear watches, the situation is much more complicated, both in terms of environmental changes and wrist movements. Moreover, the 30-meter waterproof watch basically has no screw-in crown. When swimming or rainstorm, it is easy to apply pressure to the crown and cause the crown to loosen, causing the watch to enter the water. Watchcloneprice - who makes the

What is the standard for waterproofing watches? The 30-meter waterproof watch can only meet the needs of daily life, and can resist a small amount of hand washing, face splashing and rain. Waterproof 50 meters can withstand rain, or short-distance swimming in the shallows. Waterproof for 100 meters, you can swim and snorkel. If you want to swim in the water or snorkel, you need to waterproof 200 meters. In addition, there are more powerful waterproof performances such as 500 meters, 1000 meters, 3000 meters, etc., the famous Rolex Ghost King is 3900 meters waterproof.
If you are raining in heavy rain, your watch should be at least 100 meters waterproof. It is best to choose a diving watch. However, there is still a problem. As the wearing time is extended, the key to the waterproof design of the watch is that the rubber ring will gradually age, lose its elasticity, cause cracks, and the waterproof paste will deteriorate. At this point, moisture can enter the case. Therefore, the strict diving watch must be re-tested and replaced every year to prevent the rubber ring and waterproof paste from aging into the water.
There is another point that must be paid attention to regarding the waterproofing of the watch, that is, no matter how good the waterproof performance of the watch is, it does not prevent hot water. Therefore, wearing a watch to take a hot bath, steaming sauna, this behavior is very harmful to the clock. Until now, there are no watches in the world for hot baths and saunas. Whether it is a hot bath or a sauna, the temperature difference between the temperature and the waterproof test is too great. What needs to be reminded is that solid materials have the property of thermal expansion and contraction. After thermal expansion, there will be tiny gaps when cold shrinks, and water will enter into the gap, causing the watch to enter the water. Even if the watch has good waterproof performance, there is no water in one or two times, but in the long run, it will accelerate the aging of the waterproof parts, and the water in the watch may happen at any time
