As one of the leading watchmakers in the world states, “No watch is truly waterproof” With that being said we suggest that you do not swim or shower with your watch. Brief contact with your EVN watch and water will not ruin your watch, but prolonged exposure to water will cause damage that is not covered by our warranty. Also with the exception of styles with leather bands (We do not advise contact with water if your model has leather bands as this will ruin the integrity of the leather.)
