Water Resistance

The following outlines what water resistance is, what it means exactly, and how you must care for a water resistant watch. If you have any questions, please send us an email at Info@Webjeweller.com.

Definition of Water Resistance

A watch marked as water resistant without a depth indication is designed to withstand accidental splashes of water only. Do not submerge such a watch. Higher levels of water resistance are indicated by increasingly higher acceptable depths, usually indicated in meters.

There are a variety of ways to make a watch water resistant. All such watches use rubber gaskets or "O" rings to seal the case back. A watch with a back that screws onto the case provides a higher degree of water resistance. Some crowns (the "winding stem") actually screw into the case to further increase water resistance.

Usage Recommendations

Depth	Usage Recommendation
30 meters (100 feet)	Will withstand splashes of water or rain but should not be worn while swimming or diving.
50 meters (165 feet)	Suitable for showering or swimming in shallow water.
100 meters (330 feet)	Suitable for swimming and snorkeling.
150 meters (500 feet)	Suitable for snorkeling.
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.

How to Care for a Water Resistant Watch

It is not recommended to wear your water resistant watch in a hot shower, sauna or hot tub. The extreme heat causes the metal parts to expand at a different rate than the rubber gaskets. This creates small openings that can allow water droplets to penetrate the watch. Sudden temperature changes are especially harsh. Take care not to jump into a cold pool after wearing your watch in the hot tub.

After swimming or diving in salt water, immediately rinse the watch in a stream of fresh water. If your watch has a rotating bezel, turn the bezel several times while rinsing it. This will prevent salt buildup and corrosion of the bezel ring.

Leather straps can be made to be water resistant too. Generally however, leather straps are more easily damaged by frequent exposure to water. So if you are going to wear your watch while swimming -- think of buying one with a metal bracelet or a rubber or nylon diver strap.
