Unknown underwater world is full of exploration fun, but you would probably happen to meet unexpected danger if you don’t prepare well. A reliable diving watch can not only supply you with accurate time, but help you accomplish your wonderful journey. In addition to strong water resistance, its security also embodies another 5 specific functions.

Whether swimming or instrument operation under the water, we need flexible wrists. A diving watch fastening the wrist tightly is necessary at this time. Though many diving watches are equipped with metal bracelet, some chemical components in the sea may cause light corrosion. We had better replace a rubber band with good water resistance and corrosion resistance before we decide to dive. Nowadays, it’s a good option that some watch brands developed canvas or man-made fiber straps.

Which part does have water damage for a wristwatch? Absolutely the crown. Because the crown is the only part connecting the movement to the outside. In order to prevent the water through the crown into the machine, the screw-in crown with a waterproof rubber ring was developed by watchmakers. When the crown is screwed tightly, water will be insulated outside the watch. After upgraded, bigger fluted crown is more anti-skid and more convenient to operate under the water.

Helium Escape, which is used in professional diving watches(beyond 1000-Meter water resistance), is a professional function. When professional divers works in the deep sea, they have to stay the high pressure cabin. During that time, Helium molecules keep infiltrating the watch. Once they return to the land, the watch will explode if the high-pressure Helium can’t be escaped in a short time.

You feel your longing for the light in the dark deepsea strongly, so all diving watches are equipped with bold luminous scales and hands in order that the users can see the time clearly and precisely. In the early days, watch hands and scales were coated with radium, but the material was quitted since it has too many radioactive elements. Nowadays, Super-LumiNova, good lightfastness and colorfastness, is used the most commonly.

The rotating bezel plays an important role in alerting the diver to the diving time. The bezel was marked with these scales-15, 30, 45 (also 60-minute scale). The first quarter is colored or marked specially since the diver observes a 15-minute safety stop to reduce stress during the rising period. Most of bezels are designed as unidirectional rotating bezel in order to prevent the delay time. The new built-in chronometer bezel without rotation direction limitation will be locked by screw-in crown before entering the water.
