Watch Water Resistance Explained

All is not what it seems with watch water resistance watch, you will not find a watch that claims to be waterproof. This is because no watch can be guaranteed totally waterproof.

The different levels of water resistance as expressed in meters is only academic. They refer to the depth at which a watch will keep out the water if both watch and the water are static. So for example if you have a water resistant watch and you dive into a swimming pool the pressure on the watch at the point of impact with the water will be many times greater then if you were just placing the watch into the water.

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.

Depth

The 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 chart

  • Water-resistant to 30 meters, Will withstand splashes of water or rain but should not be worn while swimming or diving.
  • Water-tested to 50 meters, Suitable for showering or swimming in shallow water.
  • Water-tested to 100 meters, Suitable for swimming and light snorkeling.
  • Water-tested to 150 meters, Suitable for snorkeling.
  • Water-tested to 200 meters, Suitable for skin diving.
  • Diver’s 150 meters, Suitable for scuba diving.
  • Diver’s 200 meters, Suitable for scuba diving.

The water resistance markings on watches in my opinion are misleading and should be redesigned to tell you the consumer what depth you can actively take your watch to while doing normal everyday activates. Without knowing a little about this subject having a watch, marked 30 meters would make me think that I could use this in a swimming pool without any worries.

Guide To Watch Water Resistance – What to Look For When Buying a Watch ?

Anyone who has bought a watch has probably seen watches with the water-resistant brand stamped on the back of the watch. The mark is to indicate how deep that watch can take in the water and to some extent how long. All watches with a waterproof brand have passed the leak test. It is a pressure test where the bars equal to the depth in meters are read. Even if a watch has the water-resistance mark, it does not mean that it has been designed for prolonged use underwater. Let’s explain this a little more before analyzing what to look for when buying water-resistance watches.  Let’s consider you are going to buy Casio LTP-E106RG-9A  from  Casio online showroom

 

 

The first thing you will notice will be the 30-meter water resistance mentioned on the back of the Casio watch. The water resistance that is measured for 30 meters means that it cannot withstand great pressure. If it reaches the 30-meter mark, the clock could break. If you carry the watch underwater repeatedly and up to 20 meters, it will eventually stop working. Water-resistance is usually intended for someone to know that their watch is safe if it falls into the water, it rains a little or even accidentally swims in a pool. In total, water resistance is not for swimming every day.

Those who dive have a different appearance in the words waterproof and waterproof. Waterproof is a term that generally does not apply to watches, but is suitable when talking about diving watches. Dive watches were designed for repeated use in the water. They have special designs to make sure they are protected against water. The first is the seal. There is a seal in place, such as a small O-ring or seal. This helps block water but does not protect it completely. A sealant or lubricant is added into the water around the edge. This sealant hardens and ensures that the internal operation of the watch is safe against water. Despite all the seals in place, a dive watch can become susceptible to water.

Dive watches will eventually be affected by pressure and temperature. These stressors combined with the aging of the seals means that the watch must undergo maintenance to reform a good seal. Dive watches are also rated for deeper depths, as divers like to visit 100 feet. Anyone wishing to swim with a watch would be better with a dive watch over the typical sports watch because they are designed to dive into the water.

Now that you understand water resistance, you can concentrate on what to look for when buying a watch. If you do not intend to swim with a watch or dive, it will be fine with your standard water resistance brand. Any watch that has a water resistance of up to 200 meters is not suitable for diving. For divers, you should look at the minimum ISO of 6425 for a depth of 100 meters. Any watch that says it is resistant to splashes and rain is not a watch for swimming or diving. Those with 100 to 200 meters can be used for swimming and even surfing, but not for diving.
