Description         how to distinguish between waterproof and non waterproof watch? The back cover of the waterproof watch will be identified by the RESIST WATER, which is not identified. Waterproof watch waterproof depth of what knowledge? Waterproof depth is mostly indicated in the axis of the pointer and at six o'clock position, such as how to distinguish between waterproof and non waterproof watch? The back cover of the waterproof watch will be identified by the RESIST WATER, which is not identified. Waterproof watch waterproof depth of what knowledge? Waterproof depth is mostly indicated in the axis of the needle and at six o'clock position, such as waterproof 300 meters for 30ATM, 300m or 300meters, or Resistance Water, Waterproof on the bottom cover. Usually watch guarantee or instructions for use in this text: Waterproof 30 meters,www.review4uwatch.com, the only anti wash splashed; waterproof 100 meters, for snorkeling or swimming, water resistant to 200 meters, water scuba diving. These instructions may seem clear, but ambiguous,www.great2usale.com, as scuba diving to a depth of only 30 meters, why the need for waterproof to a depth of 200 meters from the table? Since waterproof to 30 meters, why not wear a table to take a bath? How to interpret the meaning of it is a great knowledge! When water depth is increased by 10 meters, will increase the equivalent of a atmospheric pressure. According to this principle, making general factory in pressure gauge to test the watch waterproof performance, so some plants to mark the compressive value (bar or ATM) to represent its waterproof numerical. 1bar is equal to 1 per square centimeter of under 1 kg of pressure, so pressure 10bar equivalent can withstand the pressure of 100 meters below the surface depth is waterproof 100 meters, 20bar equivalent to water resistant to 200 meters, and so on. If the watch is only Water Resistance words without a numerical scale, according to the international standard is the equivalent of 20 meters waterproof. However, the so-called stress tests is static, when wearing a watch in the wrist or swimming, diving, to withstand the pressure is dynamic, so watch required under the instantaneous pressure is much larger than the static, so must by several times the safety factor, to ensure that the watch waterproof performance, which is why watches marked depth is much higher than the actual use of reason. Quartz watch, which is the electronic table, this kind of table, can only temporarily waterproof, can not be completely immersed in water, wash your hands,www.tourbillon4uwatch.com, wash your face can also be, take a shower, swimming and so on the best to take it out
