Protected in everyday life, bathing, accidental splashes, short swimming or car washing - it is resistant against perspiration, water vapor, rain drops.

It is tested for water resistance up to 3 ATM, and must be able to survive 30 minutes under water at a depth of 1 m (3 feet) followed by 90 seconds under a pressure corresponding to 30 meters.

What does the abbreviation ATM on a waterproof watch stand for?

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.


What does 3 ATM mean on wrist watches?

"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)


What dose 10 ATM mean on a wrist watch?

It's a watch for underwater use, it will stand pressure up to 10 Atmospheres or 100m


What does 10 ATM mean on a watch?

ATM = Atmospheres. It means the amount of pressure the watch can take in atmospheres before failure is assumed. 2 ATM is about 1/2 a meter under water. so drop it in the sink and you're ok,,, drop it in the Mariana trench and kiss it goodbye ;)


What does 5 ATM mean on a wrist watch?

"ATM" stands for ATMospheres and the number before it, refers to the number of atmospheres of pressure the watch will withstand before leaking. At sea level we are all subjected to one atmosphere of pressure, because we have one atmosphere of air above us pressing down. For every 33 feet (10 metres) underwater you go, the pressure increases by 1 atmosphere. Therefore, at 33 feet underwater the pressure is 2 atmospheres (2 ATM), at 66 feet underwater the pressure is 3 atmospheres (3 ATM), etc. So 5 ATM is equivalent to 132 feet (40 metres) underwater. In conclusion, the ATM rating of a watch is the number of atmospheres of pressure the watch will withstand before breaking/leaking. To convert ATM 's into the depth rating in metres just subtract 1 and multiply by 10. eg: 5 ATM = (5 - 1)*10 = 40 metres.


If two gases with pressures of 2 ATM and 3 ATM are mixed at a constant temperature what will the total pressure be?

2 atm + 3 atm


What is mean by 3 ATM?

That u only have 3 bucks left on ur creditcard. lol.


Are there cameras inside the ATM?

Yes there is . To watch you.


What does 1 ATM mean on a wristwatch?

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..


What does 10 ATM mean on a wrist watch?

It means 10 atmospheres. This usually indicates a watch will remain waterproof to a depth of 10 atmospheres or about 340 feet of water.


What change in pressure would result in the volume of gas increasing A 2 ATM to 3 ATM B 3 ATM to 4 ATM C 4 ATM to 1 ATM D 1 ATM to 3 ATM?

Decreasing the pressure of a gas will increase its volume -- C


If 2 gases with pressures of 2 ATM and 3 ATM are mixed at constant temperature what will the total pressure be?

2 atm + 3 atm
