The first thing to note is that even a waterproof smartwatch with a strong waterproof rating is not recommended for use in hot baths, saunas and other environments. Because high air pressure can easily damage the sealing ring, resulting in waterproof failure, water vapor as a gas is more likely to enter the watch and cause damage.

The grades of watch waterproof detection are as follows:

Level 0:

No protection, no special protection against water and moisture

IPX1:

Prevent the intrusion of water droplets, and the water droplets falling vertically (such as condensation water) will not cause damage to the appliance

IPX2:

When the appliance is tilted 15 degrees, it can still prevent the intrusion of water droplets When the appliance is tilted from vertical to 15 degrees, the dripping water will not cause damage to the appliance

IPX3:

Prevent water spray, rainwater from invading or prevent water spray from a direction less than 60 degrees from the vertical direction from invading the electrical appliance and cause damage

IPX4:

Prevent splashing water from invading, prevent water splashing from all directions from invading electrical appliances and causing damage

IPX5:

Protection against water jet intrusion Prevents water jetted from nozzles from all directions from entering the device and causing damage

IPX6:

Protection against intrusion of large waves, electrical appliances installed on the deck can prevent damage caused by intrusion of large waves

IPX7:

In order to prevent water from entering when immersed in water, the appliance is immersed in water for a certain period of time or the water pressure is lower than a certain standard to ensure that it will not be damaged due to water ingress

IPX8:

continuous diving test; test equipment, test conditions and test time: determined according to the standard and the product under test, and its severity is higher than IPX7.

If the watch is squeezed or soaked in water, it is easy to cause damage to the internal parts of the watch. In addition to looking at the watch's IP65 waterproof detection level, you also need to look at the watch's dust-proof rating. Only the watch's IP65 water resistance test and dust resistance test can meet the ideal standard, allowing you to decide whether to buy this watch for yourself.

For those who are not used to taking off the watch, choose a watch with a high IP65 waterproof detection level.
