            What does the water resistance ratings and divers watch mean?

            The Water resistance relates to pressure as measured (on a laboratory pressure test) in the equivalent of a static tank of water at a given depth under water. But please note, the faster an object is moved through or against water, eg. getting sprayed with a garden hose, plunging your arm in the water while swimming, or even taking a shower, the greater the pressure against the watch and could exceed the degree of water resistance engineered for that timepiece. For that reason, even a watch that is water resistant to 30 meters may leak (water can force it's way passed the crystal seal, case-back gasket, the setting crown, or push buttons.) if exposed to water coming forcefully from a tap, or worn whilst swimming or diving, as the increased pressure may exceed the designed resistance.

             Water resistance is tested in measurements of atmosphere (ATM) (on a laboratory pressure test). Each ATM denotes 10 meters of static water pressure. Many watch cases will list the basic measurement of 1 ATM as "water resistant." Watches that are marked "water resistant", but DO NOT specify a depth rating of from 3 ATM (Atmospheres), 50 feet, 100 meters, etc., are not designed to be submerged below the surface of the water. These watches will withstand small splashes of water but should not be worn while washing the hands or submerging the hands in water or withstand forceful water splashes eg. from the tap. Although they may withstand this condition for a while, if continually subjected to this situation, they will eventually leak. Based on our experience, if you need a watch to be water resistant enough to be able to submerge it below the surface of the water, be sure to get one that is designed with a screw-down crown and a screw-down case back or, better still, a divers watch.

            Sudden changes in temperature like going from a cool atmosphere into a hot tub can cause the rubber gaskets, base metal and steel case parts designed to protect your watch's water resistance, to breach its sealing capacity momentarily and allow water to leak in.

            Please keep in mind also, that the precision gaskets protecting the setting stem, case-back, or crystal area will break down over time, and should be inspected periodically and replaced when they reach the point where they become worn out and the danger of them leaking becomes a possibility. Also a concern is those watches that the case-back sealing area or the crown is badly corroded.

            Remember, unless specified by depth, water resistant only means "ACCIDENTAL WETTING"! Think of it like this. "Oops, didn't mean to do it, dry it off real quick", and it should be okay.

            Diver's watches had undergo specific lab test for diving purposes. Purchase a diver's watch if you spend a lot of time snorkelling or deep sea diving. A dive watch usually has a screw-down crown and a screw-down case back. The water resistance rating for these watches will be at least 20 ATM (200 meters/660 feet). 

            Common water resistance ratings:


            (1bar = 10m pressure)



            Water Resistant



















            5 bar

            10 bar

            15 bar

            20 bar


            Accidental Splashes



            Water Sports









            Professional Deep Sea Diving






            * only watches marked "Divers" on the dial should be used for diving, as they fully comply with the international standards for divers watches.

            * Watches that are used for DIVING should be inspected by a dive shop to validate it's depth rating prior to going into the water.

            Note: Your watch has to be immediately wiped dry after all water activities, no matter how much is the water resistance labelled on your watch. You must not press the buttons on the watch or pull out the winder while the watch is submerged in water or still wet, If the case, glass or seal is damaged in any way the watch will no longer be guaranteed water-resistant. Condensation can appear in any watch and is caused by a sudden change in temperature i.e. When a watch is removed from a cold room and placed into a warm room or near hot tub, or vice versa.

            The appearance of condensation does not mean the watch will not operate but it should be checked by us or any authorized service center. A watch exposed to sea water should be washed well with fresh / tap water and wiped dry immediately.

            Batteries in water-resistant watches should be replaced by authorized service center so that the seal can be checked and renewed if necessary, otherwise the watch may no longer be guaranteed water-resistant. Water-resistance is not a permanent condition. For example, the gaskets that are around the stem, case back and glass will deteriorate with time and should be inspected and changed periodically. It is good practice to change the battery hatch or case back gaskets whenever the battery is changed.
