Water resistance rating is a crucial factor to consider when choosing a dive watch. It determines how well the watch can withstand water pressure at certain depths. The higher the rating, the more water pressure the watch can handle. For recreational diving purposes, a water resistance rating of at least 200 meters (660 feet) is generally recommended. This ensures that the watch can withstand the pressure experienced during recreational scuba diving depths. It’s always safer to choose a watch with a higher water resistance rating if you plan on diving beyond recreational depths.
