Water Resistant

Certina sport watches set the standard for water resistance

Certina sport watches set the standard for water resistance.

In water sports, a watch with a minimum water resistance of 100 meters is recommended. All sports Certina watches are equipped with the "DS" or "DS + 'from system, and testing at a minimum pressure of 10 atmospheres (equivalent aa a depth of 100 meters ** at sea level) in accordance with ISO 6425.

Certina Each must undergo a series of tests for water resistance before it reaches the point of sale. The first test clock the high air pressure to ensure that air can not find their way into the watch case. The next test takes through variations of temperature in a humid environment to ensure the total absence condensation inside the watch glass. The last obstacle to be overcome by all the test Certina dive: several hours under water at high pressure to simulate the depth so that the clock has been certified and guaranteed to resist.

** Important! The classification of water resistance of our watches is Based on laboratory pressure tests comparable to the pressure conditions at which a swimmer or diver may still be exposed to the depth that corresponds to a wide range of watersports, and may show some variations. The conditions under which the clock is tested represent a basis for the minimal protection that a waterproof watch must take, and can vary in cases where strong or intense movements occur.

It should also be understood that the water resistance can not be guaranteed for a period indefinite time. It can become compromised by an accidental shock or impact to the crown, button or other areas. For this reason, we recommend that you have your watch check the resistance of water by an authorized Service Center Certina year, and has replaced any component fails, if necessary. One should not, under any circumstances, try to open a complex, modern watch yourself.
