To ensure water resistance when swimming watches need a marking of 50m water resistance. 100m means you can also safely use diving boards or similar impact water sports. 200 metres means you can go Scuba diving.
Watches without water resistant engraving on the caseback, should be protected from water and excessive amounts of moisture, steam and condensation to avoid damage.
All STORM water resistant watches are tested for the above activities, but also for low pressure activities such as cleaning the car, showering etc, which is in excess to that undertaken by similar fashion watch companies. We want to ensure there are no water/moisture problems with your watch.
However, as with all water resistant watches, we recommend you have your watch serviced every two years or when the battery is replaced, in order to maintain the quality of the seals and the lubrication needed to ensure this. The water resistance of your watch is not permanent and will deteriorate through time.
Please Note: Water resistant watches must be re-sealed when opened for servicing to maintain the water resistance. Please ask for this service if required, as this work is not standard.
