Inex is a long standing watch company that designs watches for people with an active lifestyle. A water resistant watch fit perfectly within the mission statement of the company.
ATM is the depth by which water resistance is measured on a watch. ATM stands for Atmospheres. 1 atmosphere is equivalent to appx. 33 feet depth in water. So if a watch is 3 ATM = 100 ft. water resistant.
The term "atm" means "atmosphere" It's a term used to measure pressure. One atmosphere is the atmospheric air pressure at sea level. On a watch it is a measure of water resistance. Under water the pressure increases by one atmosphere for every 10 metres of depth. So "10 atm" on a watch means it is water resistant to 100 metres. "30 atm" is water resistant to 300 metres. http://en.wikipedia.org/wiki/Atmospheric_pressure
"ATM" stands for "atmospheres," and the ATM rating on your wristwatch is the depth before the sea surface at which you can safely wear your watch. Most watches are rated between 1 ATM and 10 ATM. For more information, see the Related Link.
Yes, unless you are diving to a rather deep depth. One atmosphere is 15 pounds per square inch (or PSI.) A 5 ATM watch should be resistant to water entrainment to a pressure of 15*5, or 75 PSI. That would correspond to a depth of approximately 150 feet, depending on whether you are in fresh or salt water. Watch out, though - many watches not designed for diving have leather or other types of bands that can be damaged by water, especially salt water. (Anything you wear in salt water should be thoroughly rinsed afterwards to get rid of sea salts.)
A watch that sates it's water resistant to 3 ATM of pressure is almost always safe to shower in and you can swim in it as well. Although there are a couple of caveats. First "1 ATM" or one atmosphere is equal to the pressure of water at 33.8995 feet deep when the water is 39.2 degrees Fahrenheit. The temperature of the water will not make any difference if you are wearing the watch, since you will not be swimming in 39 degree water for very long unless you are a diver in a dry suit. If you were you would probably be wearing a watch water resistant at a much greater depth such as a Rolex. As you probably know these watches are very expensive. (A decent diving model starts somewhere in the range of $5,000.00 and goes much higher.) A Luminox Navy Seal Model only costs about $300.00, and it is water resistant to 200 meters (656 Feet). This is the same watch issued to military divers and it has proved very water resistant while swimming and showering.Basically your watch "states" it is water resistant up to 3 ATM or around 100 feet. So I would say as long as you are not scuba diving scuba diving, and the watch is made by a reputable watch maker that warranties its product you will be safe showering or swimming with your watch on.Also, there isn't any watch to my knowledge that is completely water proof since they all are man made and have seals that can leak, hence the expression, "water resistant". There are different innovations in modern watch design that are used to make a particular watch more water resistant than another such as double "O" rings around the stem, screw down stems, a cap that screws down onto an "O" ring over the stem, screw down plates onto seals around the crown, and the same on the back of the watch.On a side note, ATM, or atmospheres, is a measure of atmospheric pressure which is done in several ways such as Bars, inches of Hg (Mercury) on a weather gauge or Pounds per Square Inch which is about 14.7.
water changes from a gas to a solid to a liquid
The pressure in ATM at the normal boiling point of water is 1 ATM.
1 atm
"3 ATM" on a watch is a pressure rating for 3 atmospheres (a unit of pressure equivalent to three times Earth's atmosphere) which is roughly equivalent to 30 meters (~100 feet) of water resistance (though most manufacturers will not recommend you swim or dive with it at all)
As pressure increases from 0.8 ATM to 1.2 ATM, the boiling point of water also increases. Therefore, at 100°C and 0.8 ATM, water would boil, but at 1.2 ATM, the water would need to be heated to a higher temperature to reach the new boiling point under the increased pressure.
ATM is the abbreviation of atmosphere which is used for nautical measurements 1ATM is equivalent to 33 feet so Ur wrist watch is resistant to 33ft wile diving..
