Diving Hour is a sports watch designed for submarine diving. Its main purpose is to safely reach the surface using your underwater recording and clearing tables (called analog clocks). Most diving watches look great, and can easily be worn as a fashion accessory when not in use as diving gear. Visit this https://smartwatchratings.com/best-smartwatch-for-galaxy-s9/ for more details.
The diving time must withstand a water pressure of at least 100 meters. The original diving watch must meet the set of standards set out in ISO 6425, a global standard that allows watch makers to print the word DIVER.
Features of diving watches
Diving watches have a modest function level and must meet ISO standards. Most watchmakers also offer additional features. Although traditional diving watches are commonplace, the emergence of diving watches shows that digital diving watches are becoming more and more popular in the market. So how does a Daewoo watch differ from a standard watch? There are several features used to classify diving watches:
Water and corrosion resistance watch
Because diving watches need to be quite waterproof, watch covers are made of materials such as stainless steel, ceramics, titanium, and plastic or synthetic rubber. Diving watches can withstand external magnetic vibrations and light vibrations. Even the most popular Daewoo watches use smartwatch protection.
Rotate us (time controller)
Tracking total diving time is an important part of diving hours. Analog watches feature a rotating design that solves this. Basel’s job is to make it easy to record past leaps. The bezel rotates counterclockwise with the second or minute hand of the watch, which requires the diver to memorize the correct position of the hand and the mental arithmetic required to calculate the total jump time. Is. The bezel is a method, and can be rotated clockwise to increase the time (do not shorten it). Some diving watches have a lockable bezel, which reduces the risk of underwater change. Digital diving watches, of course, only show digital diving times.
Crystal case
Due to its great underwater power, diving watches operate a very strict crystal registration window. Common materials used in the dialog box are: artificial sapphire, acrylic glass and hard glass, each with its own advantages and disadvantages.
Acrylic glass is resistant to corrosion, but easily corrodes.
Hard glass is more abrasive than acrylic glass, but less fragile than sapphire.
Sapphire is very nail-biting, but breaks down more easily than other materials.
Most watch designers use a combination of these basic materials.
Crown
Almost all analog diving watches have a waterproof crown. To adjust or correct the time or date, the crown should be opened normally and re-screwed to change the water resistance.
Helium exhaust valve
Most diving watches are designed for “shallow” divers who are at least 200 meters above sea level. The remaining 1,000 meters are planned to be reached. Leaping to this level is called “saturated water” or “technical diving”. The problem with the Ultra Deep Saturation Dive, which is in a helium-rich environment, is that helium enters the clock. If there is no proper ventilation mechanism, the crystal registration vibration often stops due to internal helium pressure. Saturated diving manufacturers compensate by installing sketch valves to remove excess internal gas.
Belt
Most diving watches have rubber, silicone or polyurethane belts or metal watch straps that allow you to wear the watch on the sleeve of a diving suit. Watch straps often have long stretches that allow them to stretch properly.

ISO 6425 requires a dark activation rate of the watch. Most diving watches have high contrast with randomly assigned numbers, minute markers and sleeves, usually with a light-colored coat.
