One of the most interesting diving watches is that they are among the hardest watch on earth. These highly specialized sports watches are designed with features on the first watch-list of priorities. This is because, as a watch is exposed to a greater depth, the harder it is to ensure safe operation in a pressurized environment.
Diving watches can be tested as
There is a strict standard internationally to meet the needs of a true diver's watchTo be a certified diver looking for. Watches must gain a series of tests specified in ISO 6425, for the right to print the "dive watch" words on the case. Each watch transmits this identification is the ISO 6425 test method, a special type of guarantee to maintain the clock has fulfilled conditions underwater.
The first test in the test method ISO 6425 is a condensation. The test involves heating a plate of about 40-45 degrees Celsius, theClock is placed on the plate and left for a period of 10 to 20 minutes. In this period the heat at that temperature until Clock particular. Clock on the crystal surface, where a drop of water at room temperature for 1 minute left and then swept away.
If condensation forms seen in the face of the crystal, then the clock strikes the test. No further examination of this point onwards.
Another test in the process requires that the clockstested at depths less than 25% rated their depth still water conditions. Slight variations in the weather can vary the density of sea water between two and five percent, and even science has discovered that sea water is denser than fresh water.
Thermal shock test is also applied to see the diver during the procedure. An audit includes rapid changes in temperature. For a period of one hour, the clock is the first in forty degree water, ifthe time has expired, is rapidly transferred to five degrees of water. The watch is another hour before heading back to the water level again for the last forty.
By far the longest section of the ISO process is, the clock is the resistance to corrosive seawater and the test includes diving watch is immersed in a foot of water for a period of about two days. This is why most divers watches stainless steel, titanium, plastics or ceramics producedbecause these materials do not rust.
A diver's watch with Underwater
Diving watches can be seen also for the practical application of a tested under water sports. And 'mandatory that all diving watches have a monitoring mechanism for the entire time from the start of the dive.
The longer track analog watches divers using a unidirectional rotating bezel for long dives, the bezel can only turn one way and as part of the standard is necessary to ensure the distinctivenessMarkings for five minutes and a scale of 60 minutes. The clock is necessary, that his 60 / 0 minute mark will be readable in 25 meters below the surface of reading and reading time. Analog Watches dive with luminous hands to achieve this goal, while most digital watches with immersion in order to implement these backlit display.
Diving watches must also prove that job, both at 25 feet and in complete darkness. Analog watches have a second permanentLuminous-tipped hands. If the battery is low, currently have an "EOL" (End of Life) indicator.
Diving watches watches are among the most rigorously tested sport on earth, which is likely to last for a good use for many years and certainly in and around salt water, if you're a diver or not.
