Key elements of watch waterproofing
As we all know, the water resistance of a watch is determined by three key elements, namely the case structure, mirror fit, and the integrity of the apron.
As we all know, the water resistance of a watch is determined by three key elements, namely the case structure, mirror fit, and the integrity of the apron. When a watch is assembled at the factory, all three elements determine its water resistance – but keep in mind that performance will gradually degrade over time through wear and wear.
In addition, watches are tested for water resistance during the production process, not when they are sold in the store, which may be months or even years away from the factory.
Then again, the watch is usually older when it is first returned to the market 5 years after purchase. Especially the cracks on the glass mirror and the oxidation of the waterproof apron on the lugs/bottom. Compared with a diving watch with a water resistance of 200 meters, an everyday watch with a water resistance of 30 to 50 meters has fewer gaskets, a thinner mirror, and a lighter case.
This does not mean that a watch with a water resistance of 50 meters is not suitable for swimming. It is indeed not recommended to wear a daily watch for swimming and other water sports, but leisure swimming or even snorkeling will not cause damage to the watch as long as it is properly maintained. Wearing the watch to wash hands, or immersing it in water may cause the watch to enter the water, but the reason is not the depth rating, but the quality of the watch does not meet the 50-meter waterproof standard.
