Ernest Jones Watch Buyer's Guide
Water Resistancy
Introduction to water resistant watches
Choosing a watch from Ernest Jones that is water resistant whether it's for sporting reasons or just because you love the brand, we want to make sure you have an understanding of water resistance measurements before you make the decision to purchase.
How water resistance works
Water resistance is the ability of a watch to withstand splashes of water. Water resistance ratings are listed in depths or pressure, usually metres which appear on the watch dial. This depth rating actually represents the results of a static pressure test, undertaken in laboratory conditions. Therefore, the number of metres shown does not mean that is the underwater depth the watch can go. A watch marked as water-resistant without a depth indication is designed for accidental splashes only. Take a look at the water resistance chart for specific information.
Care & maintaining a water resistant watch
The following tips will help you care and maintain your watch's water resistancy for as long as possible.
- Batteries in a water resistant watch should be changed only by the manufacturer or approved service agent so that the seal can be checked and renewed if necessary. If this is not done, the watch can no longer be guaranteed water resistant.
- Remember leather straps are more easily damaged when exposed to water frequently.
- After swimming or diving in seawater, rinse your watch in fresh water afterwards and dry thoroughly, to prevent a build up of corrosive salt.
- Although your watch is water resistant avoid wearing it in a hot shower or sauna as extreme heat can cause watch seals to expand and create openings allowing water droplets to get inside.
If you are looking for a performance divers watch then see the water resistance chart for more guidance. For a watch suitable for scuba diving, a design featuring a screw in crown keeps the watch water tight as the crown screws directly into the watch case.
