One of the coolest things is that diving watches are among the toughest watches on the planet. These highly specialized sports watches are designed with features first in the list of priorities of the watchmaker. Because the watch is subjected to greater depth, the harder it is necessary to ensure reliable operation in a pressurized environment.How Other Watches TestedThere is an international standard that is stricter than sub real-time clock must meet to be certified diver watch.
Watches must pass a series of tests specified in ISO 6425, to win the right to print the words "diver's watch" on the case. All performances will sign to meet the ISO 6425 test procedure is a particular type of guarantee that the clock test conditions.The first submarine in the process of ISO 6425 is evidence of condensation. The test involves heating a plate to about 40-45 degrees Celsius, the clock is then placed on the plate and left for a period of ten to twenty minutes.
During this period the watch heats up at that specific temperature. On the face of the watch crystal, a drop of water at room temperature is placed and left for a minute, then wiped condensation off.If seen in the crystal shape of the face and the clock does not pass the test. No further test is performed with this test procedure requires time on.Another watches are tested to a depth equal to 25% below their depth in calm water.
slight variations in climate can cause the density of seawater varies from two to five percent and is also well established by science that sea water is denser than fresh water.Thermal crash test is also applied to see the underwater testing process. The test provides rapid changes in temperature. For a period of one hour, the clock is first in forty-degree water, then when the time expires, is rapidly transferred to five degrees of water.
The watch is left for another hour before being moved for forty-degree water again for a final hour.By by far the longest in the ISO test procedure is to test the resistance of the watch to the seawater corrosive and involves diver's watch is immersed in a foot of water for a period exceeding two days. This is why most diving watches are made of stainless steel, titanium, plastic or ceramic, these materials are not rust.
Using diver watch watches WaterDiving Below are tested for the practical application of using a sports watch submarine. And 'mandatory that all diving watches have a mechanism to monitor the total amount of time from analogue clock dive.Most Diving use a unidirectional rotating bezel for tracking bottom time, the telescope can be rotated in one direction and the the standard must have markings at intervals of five minutes to an hour and a scale.
The clock must have his minutes 60 / 0 points can be read at 25 meters below the surface and the time to read display itself. diving watches with luminous hands reach analogue, most diving watches digital implementation with a payback Watches informed look screen.Divers should also indicate if the work is 25 meters in complete darkness. second peak luminescent analog clocks have a handrail. When the battery is exhausted, must submit an "end of life (EOL) indicator.
