A watch which is being considered as water resistant can be wet by water but only up to an extent and not for so long. Most of the watches are being categorized to different degrees of the depth of immersion. Thus, one must always remember that the ratings of resistances provided by the manufacturers are based on the controlled conditions from laboratories.
Resistances of watches decrease over time because of some constant changes in conditions and in aging. Another thing that needs to be remembered importantly is the difference between being resistant and being waterproof. One best example for this is changing the battery of your watch. When the seal or covering is put back, it cannot protect your watch anymore like before. And because of this, a watch water resistance testing Cambridge would be very important.
In Cambridge, MA, manufacturers would most likely suggest their clients to have their watches tested by them every year and also every after the batteries are changed. Testing can help in ensuring that the sealing was properly done, thus, avoiding waters to get in. Tests are done in laboratories by the manufacturers with specifically stated controlled conditions. The results during a test may be fully different to real life actions.
In the test, a chamber filled with half air and water will be used, wherein the item is going to be placed. The item is taken out from water. And while increasing the pressure of the air, it will be immersed into it very slowly. When it is already immersed completely, the air pressure will be released slowly. When bubbles come out, this would mean that your watch does not have any resistance.
The shapes of gasket seals may also be affected by the temperature of waters such as in hot showers and hot tubs. This is possible to happen when dipping the item to a hot temperature and immediately dipping it into cold temperature. For example, the item is placed in a hot tub and directly transferred to pool right after. Stressing the gaskets through rapid changes in pressure can rupture them.
The resistance in watches is being obtained by three important factors. These factors are case back, crown, and gaskets. The attachment of case backs into watches may imply different levels of resistances. There are two types of case backs and these are the snap on and screw in.
For a snap on type, pressure seals it and for this reason, it is considered as the least resistant. Another level is screw in type. This type allows the case back to be sealed tighter. This screw in type is threaded before it is screwed into case. Using the threading process and the gasket as seals create double seals.
Crowns as well have two types such as the crown stem and screw down crown. When the crown is moving continuously, the gasket becomes stressed constantly. Screw down types are threaded, having screws that match the tube being threaded. These are essential for watches that submerge in water.
O rings also refers to gaskets. The common materials used for these are either Teflon, rubber, or nylon. These are forming watertight seals in joints wherein crown, crystal, and caseback will meet the watch case. Gaskets often break down easily and erode as well, causing the diminishing of resistance.
