Waterproof watches have become an essential accessory for individuals who lead active lifestyles, from swimmers to divers, and even those who simply enjoy the occasional splash in the rain. However, the term “waterproof” is often misunderstood, leaving many consumers unsure about the true capabilities of their timepieces. In this article, we will explore what qualifies as a waterproof watch, the different levels of water resistance, and how to properly maintain your watch to ensure its longevity and durability.
1. The Myth of ‘Waterproof’
Before diving into the specifics of water-resistant watches, it’s essential to address a common misconception: no watch is entirely waterproof. The term “waterproof” has become a marketing tool, but in reality, the more accurate term to use is “water-resistant.” Watch manufacturers are required to specify the degree of water resistance of their watches, typically measured in atmospheres (ATM) or meters (m). These measurements indicate the depth at which a watch can withstand water exposure without being damaged. However, even watches with high water resistance are not immune to water damage if exposed to conditions beyond their rated limit.
2. Water Resistance Ratings: What Do They Mean?
Water-resistant watches are rated based on how well they can handle exposure to water. These ratings are standardized by the International Organization for Standardization (ISO) and provide a helpful guideline for understanding a watch’s capabilities.
50 Meters (5 ATM or 5 BAR)
A watch rated to 50 meters (or 5 ATM/5 BAR) is suitable for everyday use, such as handwashing, light splashes, and rain. However, it is not recommended for swimming or submerging in water for extended periods.
100 Meters (10 ATM or 10 BAR)
Watches rated to 100 meters (or 10 ATM/10 BAR) are more robust and suitable for swimming, snorkeling, and other water-based activities. They can withstand light submersion, but prolonged exposure to water at these depths may cause damage over time.
200 Meters (20 ATM or 20 BAR)
A 200-meter rating is ideal for professional swimmers, divers, and water sports enthusiasts. Watches with this rating can handle swimming, snorkeling, and even shallow scuba diving. However, they are still not suitable for deep-sea diving or prolonged submersion at greater depths.
300 Meters (30 ATM or 30 BAR) and Above
Watches rated to 300 meters (or 30 ATM/30 BAR) and beyond are considered diving watches. These are designed for deep-sea divers who need a reliable timepiece that can withstand the extreme conditions of underwater exploration. These watches are engineered with more robust sealing mechanisms and are built to resist water at great depths, even during professional diving activities.
3. Water Resistance and Watch Design: What to Look For
When it comes to waterproof watches, the construction and materials used play a significant role in their resistance to water. Here are a few design features that can enhance a watch’s waterproof capabilities:
Seals and Gaskets
The most important component of a water-resistant watch is its sealing system. Watches rely on gaskets made of rubber, silicone, or similar materials that create an airtight seal around the case and crown. These seals prevent water from penetrating the watch during submersion. The quality and condition of these seals are vital in maintaining a watch’s water resistance.
Screw-Down Crown
A screw-down crown ensures that the watch’s crown is tightly secured to the watch case, preventing water from entering the movement through the crown stem. This feature is particularly important for diving watches that are exposed to high-pressure environments.
Case Back and Crystal
The case back of a waterproof watch is typically screwed in or sealed with rubber gaskets to provide an additional layer of protection against water ingress. Similarly, the watch crystal—often made from mineral glass or sapphire—should be tightly fitted to prevent water from seeping in through the top of the watch.
4. How to Properly Maintain Your Waterproof Watch
To ensure your waterproof watch remains functional over time, proper care and maintenance are crucial. Here are some tips to extend the life of your water-resistant timepiece:
Regular Inspections
Water-resistant seals and gaskets can wear down over time due to regular use, exposure to heat, or environmental factors. It’s a good idea to have your watch serviced every 1-2 years, especially if it’s exposed to harsh conditions such as saltwater or chlorine. A professional watchmaker can inspect the gaskets and seals and replace them if necessary.
Avoid Sudden Temperature Changes
Extreme temperature changes can weaken the seals of your waterproof watch. When exposed to high heat or cold, materials like rubber can expand or contract, potentially compromising the watertight seals. Avoid exposing your watch to hot tubs, saunas, or other environments with drastic temperature fluctuations.
Rinse After Exposure to Saltwater or Chlorine
Saltwater and chlorine can degrade the seals and components of your watch. After swimming in the ocean or using the watch in a pool, it’s essential to rinse the watch with fresh water to remove any harmful residues that could damage the watch over time.
Avoid Pushing the Crown Underwater
If your watch has a manual crown, be sure not to push or pull the crown while it is submerged in water. Even if the watch is rated for water resistance, manipulating the crown underwater could cause water to enter the case.
5. What to Do If Your Watch Becomes Water-Damaged
Despite your best efforts to protect your watch, accidents can happen, and water may still seep inside. If you notice any condensation inside the watch or experience a sudden loss of timekeeping accuracy, it’s essential to act quickly. Water damage can cause the internal movement to rust, compromising the watch’s function. Here are some steps to take:
– Dry the Watch: Remove the watch from water immediately and dry it thoroughly using a soft cloth. If you suspect water has entered the case, place the watch in a bag of silica gel or uncooked rice to absorb moisture.
– Take it to a Professional: If your watch shows signs of water damage, it’s essential to take it to a professional watchmaker for inspection and repair. If the seals or gaskets are damaged, they can be replaced, and the watch can be properly resealed to restore its water resistance.
6. Are There Alternatives to Waterproof Watches?
While waterproof watches are highly functional and versatile, some individuals prefer alternative methods to protect their timepieces when engaging in water activities. One option is using a watch protector, a waterproof case that shields the watch from exposure to water. However, these are often bulky and may limit the accessibility of the watch’s features.
For those who engage in extreme water sports or activities, it’s always best to choose a professional diving watch that has been specifically engineered to handle the demands of deep-sea environments. These watches undergo rigorous testing to ensure their durability at great depths.
Conclusion: What Makes a Watch Truly Waterproof?
A waterproof or water-resistant watch is a versatile and reliable companion for anyone who needs a timepiece capable of withstanding water exposure. Understanding the different water resistance ratings and the construction behind these watches is essential for choosing the right one for your lifestyle. Always keep in mind that waterproof is a misleading term, and no watch is impervious to water. By selecting a watch with the appropriate water resistance rating for your activities and maintaining it properly, you can ensure its longevity and reliability in any situation.
