How to distinguish waterproof watches

Generally, waterproof watches are not suitable for use in hot baths, saunas, or environments with large temperature changes. Because the waterproof rubber ring is affected by temperature, it will expand and contract, resulting in voids and accelerated aging, thus affecting the waterproof function. Moreover, the surrounding water vapor molecules are relatively small, and it is easy to penetrate into the watch body, causing damage to the internal machinery.

If it's just a little mist, it will go away on its own over time, or you can bake it under a light bulb, but not over a fire. Or you can put the watch face inward and the bottom case outward, and wear it on your wrist, and the water vapor can be eliminated after two hours. If there is a lot of water in, and water droplets are visible, you should find a professional repair shop as soon as possible. Although life waterproof watches have undergone a certain waterproof treatment, they are generally not strictly inspected. It is recommended to avoid contact with water when wearing them to prevent accidents. Watches are high-precision items, please take care of them.
