We know that diving watch is waterproof that allow the wearers to take it when diving or swimming. But we have ever heard that some diving watches have been broken for there’s water entering. Why?
In theory, the waterproof rating of the watch is carried out in the laboratory, and the temperature is kept at a static temperature of 20℃ to 25℃, but when the watch is actually taken to dive, the water temperature, water flow and pressure may change instantaneously. This caused the water in the watch that should be waterproof. Another reason must be the rubber seal. It may be maturing in daily life. A well-protected rubber ring can be used for a few more years while If you don’t carefully rubber ring should be replaced within three years.
Why the watch appearance parts are generally not covered by the warranty?
In fact, not all the components of the wristwatches are guaranteed, such as bracelet, case, crown and sapphire are not guaranteed. For example, the scratching and aging of the Rolex fake watch with black dial appearance are normal, and the flaws beyond the range may be considered as human error. If scratches, pits, discoloration, chipping or gold plating falling off happen, the responsibility is not clear.
Are the diamonds on the wristwatches true?
The grade of diamond is very strict, which is divided according to weight, color, clarity and cut. Therefore, most of the diamonds on the watch are artificial diamonds and there are few watch brands engraved real diamonds. See the Cartier knockoff watch with blue Roman numerals hour markers on the picture, all the dial, case, crown and bracelet have been engraved with diamonds, and if they are not artificial diamonds, the price will be expensive and scary.
