A gasket or O ring is used to make a watch water resistant these can be made of rubber ,nylon or Teflon and form a water tight seal at all the joints including the crown (the winding stem), case and where the crystal glass meets the watch case. Another aspect of water resistance is the back of the watch, a screw on back is far superior to a push on back. DepthThe depth that a watch can be used at is a bit confusing a watch marked as a water resistance of 10 meters you would initially think that you could safely use that watch in a swimming pool as long as you do not go deeper then 10 meters. This is not the case, as a watch that is water resistant to 10 meters is designed not to be used under water and can only withstand light splashing of water. Even a watch marked as water resistant to 30 meters should not be worn while swimming in a deep pool. For swimming you are looking at the minimum of 100 meters water resistance to safely use this in a swimming pool.Things that affect water renitence in watches You should not use you watch in a hot tub or sauna, as the heat will make the metal within the watch expand at different rates then the gaskets this can allow water to get inside your watch.Water resistance chartWater-resistant to 30 meters, Will withstand splashes of water or rain but should not be worn while swimming or China Pipeline Booster Pumps Factory diving.
