Water Resistance is not Water Proof!

What is Water Resistance?
Every watch is designed differently and the individual design of each watch determines how resistant to water pressure that watch is. You should always check the water resistance measure of a watch before using it, so you can decide when to wear it and when to take it off.

What is the ATM?
The ATM of a watch is short for Atmospheres and is a measure of the level of water pressure a watch is designed to withhold. A higher ATM means that a watch can withhold more water pressure, whilst a lower ATM mean that it was designed to withstand less pressure.
