Well it also Stands for “atmospheres” which you see on the back of some watch.
Like 3ATM,5ATM & so on.
Most Skagen and Pronto Watches are rated at 3ATM, 5ATM or 10ATM for water resistance. What does this rating mean?
ATM or “atmospheres” is the amount of pressure a watch can withstand before leaking. A 3ATM watch will withstand pressures equivalent to about 30 meters, or 100ft under water. It is important to note that this is a measure of pressure NOT depth. For example, the pressure from the water coming from the shower hitting the seals of the watch is far greater than 3 atmospheres.
The following are “real world” examples of the water resistance of each rating:
3ATM - Water resistant to 30 meters (100 feet). Will withstand splashes of water or rain but should not be worn while swimming or diving.
5ATM - Water tested to 50 meters (165 feet). Suitable for showering or swimming in shallow water.
10ATM - Water tested to 100 meters (330 feet). Suitable for swimming and snorkeling.
Not Water Resistant
You will know that your watch is NOT water resistant if there are no markings on the watch.
