Watches have been an integral part of human history for centuries. Not only do they serve the practical purpose of keeping time, but they also reflect our sense of style and personality. Whether you prefer a classic and elegant timepiece or a rugged and sporty one, one aspect that often goes overlooked is water resistance. Understanding water resistance in your watch and knowing how to properly maintain and care for it is essential to ensure its longevity and functionality. In this article, we will delve into the world of water-resistant watches, exploring what water resistance means, how it is measured, and how you can take care of your watch to ensure it continues to function accurately and reliably.

The Significance of Water Resistance

Water resistance is a critical feature of a watch, especially in a world where we encounter various water-related activities in our daily lives. Whether you’re washing your hands, caught in the rain, or engaging in water sports, having a watch that can withstand exposure to water is invaluable.

  1. Defining Water ResistanceTo understand water resistance, it’s crucial to define what it means. Water resistance refers to a watch’s ability to prevent water from entering its case and damaging the movement, dial, and other internal components. A watch is considered water-resistant when it can resist the penetration of water to a certain extent. The ability to do so depends on the watch’s design, materials, and manufacturing techniques.
  2. Water Resistance RatingsWater resistance is typically measured in meters or atmospheres (ATM). The rating indicates the depth to which a watch can be safely submerged without water entering the case. It’s important to note that this rating is a static measure and doesn’t account for factors such as water pressure during activities like swimming, diving, or showering.
    • 1 ATM (10 meters): A watch with a 1 ATM rating is resistant to splashes and light rain. It’s not suitable for submersion.
    • 3 ATM (30 meters): Watches with a 3 ATM rating can withstand accidental splashes and brief immersion in water. They’re safe for everyday activities but not recommended for swimming or diving.
    • 5 ATM (50 meters): Watches with a 5 ATM rating are suitable for swimming and showering but not for diving or snorkeling.
    • 10 ATM (100 meters): Watches with a 10 ATM rating are designed for recreational water activities, including swimming and snorkeling, but not for deep-sea diving.
    • 20 ATM (200 meters): Watches with a 20 ATM rating are considered suitable for most water-related activities, including recreational scuba diving.
    • Diver’s Watches: Some watches, often referred to as “diver’s watches,” are designed to meet specific ISO standards and are suitable for professional diving at greater depths. These watches typically have a water resistance rating of 200 meters or more.
  3. Understanding Watch Seals and GasketsTo achieve water resistance, watches are equipped with various seals and gaskets. These components are strategically placed throughout the watch to create a barrier that prevents water from seeping into the case. The most critical areas where these seals are located include the case back, crown, and crystal. It’s important to note that over time, these seals can deteriorate, compromising the watch’s water resistance. Regular maintenance is crucial to ensure these seals remain effective.

Caring for Your Water-Resistant Watch

Now that we have a fundamental understanding of water resistance, it’s essential to know how to properly care for your water-resistant watch to maintain its integrity and functionality.

  1. Avoid Exposure to Water Beyond the Watch’s RatingIt may seem obvious, but it’s crucial not to exceed the water resistance rating of your watch. If your watch has a 3 ATM rating, it’s best not to submerge it in water or wear it during activities that involve significant water exposure. Knowing your watch’s limits is essential to keeping it in good condition.
  2. Regularly Check Seals and GasketsAs mentioned earlier, the seals and gaskets in your watch can deteriorate over time. It’s a good practice to have your watch’s water resistance checked by a professional at regular intervals, especially if you frequently expose it to water. If you notice any signs of wear or damage to these components, have them replaced promptly to maintain the watch’s water resistance.
  3. Rinse After Exposure to SaltwaterIf you’ve worn your watch in saltwater, whether for swimming or other activities, it’s essential to rinse it with fresh water afterward. Salt can be corrosive and may damage the watch’s materials and seals over time if not removed.
  4. Avoid Sudden Temperature ChangesRapid temperature changes can cause condensation to form inside the watch, potentially damaging its movement. Avoid exposing your watch to extreme temperature fluctuations. For example, don’t jump into cold water with a hot watch.
  5. Protect the CrownThe crown, which is used to set the time and date on your watch, is a potential entry point for water if not properly sealed. Always ensure that the crown is fully pushed in and screwed down if your watch has this feature. This step is crucial in maintaining the watch’s water resistance.
  6. Regular ServicingRegardless of your watch’s water resistance rating, regular servicing by a professional watchmaker is essential for its longevity. A professional can inspect the watch, replace worn components, and reseal it as needed.
  7. Choose the Right Strap or BraceletThe choice of a strap or bracelet for your watch can affect its water resistance. Rubber or metal bracelets are often more water-resistant than leather straps, which can absorb moisture. Consider the type of strap you use and how it might impact your watch’s exposure to water.
  8. Use a Watch Winder for Automatic WatchesIf you own an automatic watch and plan to store it for an extended period, consider using a watch winder. Keeping the watch running can help maintain the lubrication of its movement and, in turn, its water resistance.

Common Misconceptions About Water-Resistant Watches

There are several common misconceptions surrounding water-resistant watches that can lead to confusion and improper care. Let’s address some of these myths.

  1. Water Resistance Is PermanentWater resistance is not a permanent feature of a watch. Over time, seals and gaskets can deteriorate, reducing a watch’s ability to resist water. It’s essential to have your watch checked and serviced regularly to maintain its water resistance.
  2. Water Resistance Is the Same as WaterproofWhile the term “waterproof” is often used colloquially, it’s not entirely accurate. No watch is entirely impervious to water, and even the most water-resistant timepieces have limitations.
  3. You Can Swim With Any Water-Resistant WatchNot all water-resistant watches are suitable for swimming or diving. The water resistance rating indicates the watch’s intended use. It’s essential to match the watch’s rating with the activities you plan to engage in.
  4. Water Resistance Applies to Hot Water or SteamWater resistance ratings are based on cold water, not hot water or steam. Exposing your watch to hot water or steam can lead to the expansion of air inside the case, potentially compromising the watch’s integrity.
  5. Water Resistance Doesn’t Change Over TimeAs a watch ages, its water resistance can decrease due to wear and tear on seals and gaskets. Regular maintenance and servicing are crucial to ensure the watch continues to meet its water resistance rating.


Water resistance is a crucial feature of any watch, ensuring it remains functional and reliable in various daily activities. Understanding the meaning of water resistance, how it is rated, and how to care for your water-resistant watch is essential for watch enthusiasts and owners. By following proper maintenance practices, respecting the watch’s water resistance rating, and addressing common misconceptions, you can enjoy your timepiece for years to come, knowing it will continue to keep time accurately and withstand the elements. Water resistance, like the passing of time itself, is a characteristic that, when respected and properly cared for, can be a testament to the enduring craftsmanship of a well-made watch.
