The waterproof specifications of general watches are divided into the following: 30 meters, 50 meters, 100 meters, 300 meters, 500 meters.

30 meters, refers to the general life waterproof, is the water droplets splashed when washing hands, as well as the raindrops falling under the light rain, but the attention can not be too long, can not be worn in the sauna.

50 meters, no different from 30 meters, can be ignored.

100 meters, you can take him to wash the car, shower, but can not be soaked in the water.

300 meters for swimming, but only for shallow swimming (not understandable at 300 meters).

500 meters, this level of the table can be submerged 100-200 meters underwater, there may be more, but it may be the limit that the watch can withstand, can not be used to test the performance of the watch.

Finally, don't understand the depth of water resistance as the depth in the water. The pressure theory is correct, but the others are wrong. And these are for steel belts, plastics, rubber straps, if it is a belt. It is best not to stick a little water, including sweat, which will deform the strap. In addition, any waterproof watch, no matter how much water is marked, cannot be used for hot water.
