What is the difference between waterproof watches?
The waterproof function of the watch is usually divided into 30 meters, 50 meters, 100 meters and so on. It is mainly distinguished by the waterproof rubber ring on the surface, back cover, crown and others reaching the corresponding waterproof standard. The 30-meter (3ATM, that is 3 atmospheres) water-resistant watch can be used for daily grooming or rain, that is water droplets only splash on the surface without any water pressure on the watch. The 50-meter waterproof watch can be used for swimming and general housework, and the 100-meter waterproof watch can be used for underwater work such as swimming and diving.
Generally, waterproof watches are not suitable for use in hot baths, saunas, and 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.
The crown should be kept in the normal position, the threaded crown should be tightened, and the crown should not be adjusted in water.
Even for a professional waterproof watch, its waterproof rubber ring should be replaced in time after one year, otherwise its waterproof performance will not be guaranteed. It is best to replace the waterproof parts of the quartz watch every time the battery is changed to ensure good waterproof performance.
