My new watch says it is water resistant, but what exactly does that mean? And how do I care for a water resistant watch?
   
The Definition of Water Resistance
  A watch marked as water resistant without a depth indication is designed to withstand accidental splashes of water only. You should not submerge such a watch in water at any time. Increasingly higher acceptable depths, normally indicated in meters, usually indicate higher levels of water resistance.
There are a variety of different ways to make a watch water resistant. All such watches use "O" rings or rubber gaskets to seal the back of the case. A watch with a back that screws onto the case provides a higher degree of water tightness. Some crowns (the "winding stem") actually screw into the case, which increases water resistance even more.
Usage Recommendations
  These are recommendations for the usage of water resistant/water proof watches.
   
Water-resistant to 30 meters (100 feet). Will withstand splashes of water or rain but should not be worn
  while swimming or in any water sport activities.
Water-resistant to 100 meters (330 feet). Suitable for swimming and snorkelling.
Water-resistant to 150 meters (500 feet). Suitable for snorkelling.
Water-resistant to 200 meters (660 feet). Suitable for skin diving.
Diver's 150 meters (500 feet). Meets ISO standards and is suitable for scuba diving.
Diver's 200 meters (660 feet). Meets ISO standards and is suitable for scuba diving.
   
  Please note that we do not recommend swimming or diving with your watch unless it has a screw-down crown (also known as 'screw-lock' or 'screw-in' crown) and is water-resistant to at least 100 meters.
