We understand that water resistance ratings for watches can be confusing, and we want to provide you with a clear understanding of what these numbers indicate: 30 meters (3 ATM): A watch with a water resistance rating of 30 meters (3 ATM) is suitable for everyday use and can withstand splashes, rain, and brief immersion in water. However, it is not suitable for swimming, showering, or water sports activities. 50 meters (5 ATM): A watch with a water resistance rating of 50 meters (5 ATM) offers additional protection compared to a 30-meter rating. It is suitable for swimming and surface water sports but not recommended for scuba diving or high-impact water activities. 100 meters (10 ATM): A watch with a water resistance rating of 100 meters (10 ATM) is suitable for swimming, snorkeling, and surface water sports. It can handle recreational scuba diving at shallow depths. However, it is not designed for deep-sea diving or prolonged exposure to water at significant depths. 200 meters (20 ATM): A watch with a water resistance rating of 200 meters (20 ATM) is more robust and suitable for professional diving, including scuba diving at significant depths. It can withstand exposure to water and pressure at more substantial depths, making it an excellent choice for diving enthusiasts. Important Points to Note: Water resistance ratings are based on laboratory tests under specific conditions and do not account for factors like temperature changes, water pressure variations, or aging of the watch's seals. Therefore, it is advisable to avoid exposing your watch to extreme temperatures or sudden temperature changes. Water resistance is not a permanent feature and can deteriorate over time due to wear and tear, aging of materials, or accidental damage. We recommend regular maintenance and periodic checks by a professional watch service center to ensure the continued water resistance of your timepiece. It is essential to follow the manufacturer's guidelines and recommendations for your specific watch model. Avoid operating the watch's crown or buttons while it is submerged in water, as this may compromise its water resistance. If your watch comes into contact with saltwater, chlorine, or other chemicals, rinse it thoroughly with fresh water and dry it carefully to prevent potential damage. We hope this explanation clarifies the water resistance ratings of our watches.
