There are two basic levels of water resistance for our watches, 3 ATM and 5 ATM, the details section of the product page will inform you as to the level. Here's a breakdown of both...

3 ATM or 99 feet
In technical speak this means they have "been tested to withstand static pressure for a only a short period of time at the stated depth." What this means in non-technical speak is they can be exposed to water, but should not be submerged in water for long periods of time. So don't worry about sweating on them, wearing them in the rain or washing your hands in them. However, you should try to avoid swimming in them and definitely no diving! If you do get thrown in the pool and your watch goes dead, it should be ok if you let it air dry for a couple of days. If not, send it back and we'll replace it or provide you with a refund.
Below is the Industry Organization for Standardization (ISO) definition of 3 ATM water resistance, for those of you who are interested in the subject :)
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.
5 ATM or 165 feet
You would think this makes a big difference in the definition of water resistance but according to the ISO the only change is you can now go parachuting, hang gliding and skiing in it. We don't come up with these activities, we swear! Here's the official definition by the ISO:
Protected in everyday life, bathing, accidental splashes, short swimming, car washing, parachuting, hang gliding and skiing - it is resistant against perspiration, water vapor, rain drops.

Yes, any jeweler or watch shop can change the battery on any of our watches... or contact us and we can give you directions on how to replace it.
