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.

What does 3 ATM mean on a wrist watch?
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
