1.Q.Why do diving watches require an anti-corrosive flexible strap?
Under water, we need to flex our wrists. At this time, the watch needs to be tightly attached to the wrist. Although many diving watches are equipped with metal straps, the chemical composition of seawater can cause slight corrosion, so it is still recommended to replace the rubber strap with better water resistance and corrosion resistance when diving. A canvas or man-made fiber strap is also a good choice.
2.Q. Why do diving watches require a screw-in anti-skid crown?
The most easily accessible part of a watch is the crown. In order to prevent water from entering the movement through the crown, watchmakers have developed a design called a screw-in crown - a joint made of rubber with a rubberized apron at the joint of the crown, when the crown is tightened The water is strictly isolated from the watch.
3.Q.Why do diving watches require drainage?
"Draining" is a very professional function,. Because full-time divers spend too much time decompressing. Therefore, they must live in the high-pressure submersible tank in the deep sea for a long time, but at this time, the gas will be dissolved in the blood, so the air used in the general diving cabin is a "He" oxygen mixture. Since the molecules of helium are smaller than the water molecules, when we are under high pressure for a long time, the helium molecules will penetrate into the waterproof watch to make it full of high-pressure helium. Once returned to the surface, the high-pressure helium in the watch cannot be short. When the time is exhausted, the watch will explode due to high pressure.
