Whether you’re an avid swimmer, a frequent traveler, or simply someone who gets caught in the rain, ensuring your watch is waterproof is critical to its longevity and functionality.
The term ‘waterproof’ can often be a misnomer since no watch is entirely immune to water damage, but rather they are water-resistant to a certain degree. Here’s how you can ensure the best protection for your watch against water damage.
Key Takeaways
- Understand Water Resistance Ratings: Watches are rated for water resistance based on pressure they can handle but this doesn’t equate to diving depth. A 30-meter rating means it can withstand pressure up to 30 meters static, not active diving.
- Regular Maintenance: To maintain water resistance:
- Seals and Gaskets: Replace every 1-2 years or before extensive water exposure.
- Crown and Pushers: Should always be properly sealed and screwed down.
- Case and Crystal: Inspect for cracks or scratches that may allow water ingress.
- Water Resistance Testing: Have your watch tested at a service center, which simulates water pressure in a special chamber to detect leaks.
- Understanding Your Watch’s Limits: Always read and follow the manufacturer’s instructions for water resistance and avoid exposing your watch to conditions beyond its specified limits.
- Cautions for Watch Care:
- Avoid exposing your watch to hot water, which can damage seals due to thermal expansion.
- Rinse your watch with fresh water if it comes into contact with saltwater or chlorine.
- Avoid Risky Situations: Do not wear your watch during high-impact water sports or deep-water activities unless it is specifically designed for such purposes.
Understanding Water Resistance in Watches
Before diving into waterproofing, it’s essential to understand what water resistance ratings mean. Watches are typically rated by their ability to withstand pressure at a certain depth, which is measured in meters, feet, bars, or atmospheres (ATM).
A watch with a water resistance rating of 30 meters does not necessarily mean it can be used for diving to that depth, but rather it can withstand the pressure equivalent to being static under 30 meters of water.
Best Practices for Waterproofing Your Watch
Regular Maintenance Checks
- Seals and Gaskets: The rubber seals and gaskets that make your watch water-resistant can deteriorate over time. It’s important to have these checked and replaced by a professional watchmaker or service center every 1-2 years or before any extended exposure to water.
- Crown and Pushers: Ensure that the crown and any pushers are properly sealed and screwed down if applicable. These are common entry points for water.
- Case and Crystal Integrity: Have the watch case and crystal inspected for any cracks or scratches that could allow water to seep in.
Water Resistance Testing
After maintenance checks, have your watch undergo a water resistance test. This can be done at most watch service centers. The test involves placing the watch in a pressure chamber to simulate water pressure at various depths.
Water resistance is tested in a few different ways:
- Dry testing: A watch is placed in an air-pressure chamber, and the case is checked for changes in air pressure.
- Wet testing: A watch is immersed in water and pressure is applied to simulate different depths.
Understanding Your Watch’s Limits
- Read the Manufacturer’s Instructions: Familiarize yourself with the manufacturer’s specifications regarding water resistance and heed their advice for the use and care of the watch in water.
- Avoid Hot Water: Hot water can damage the seals of the watch more than cold water due to thermal expansion. Therefore, avoid hot showers, baths, and hot tubs with your watch on.
- Rinse After Use: If your watch is exposed to saltwater or chlorinated water, rinse it with fresh water afterward to prevent corrosion and damage to the seals.
Avoiding Risky Situations
- High-Impact Sports: Avoid wearing your watch during high-impact water sports where it could be subjected to forces that exceed its water resistance rating.
- Extreme Depths: Do not use a regular water-resistant watch for deep-water activities like diving unless it is a dive watch specifically designed for that purpose.
What Are the Various Levels of Water Resistance?
Water resistance in watches is measured in meters, but this rating refers to the pressure a watch can withstand rather than the depth it can be taken to underwater. Common ratings include:
- 30 meters (3 ATM): Resistant to splashes or brief immersion in water.
- 50 meters (5 ATM): Suitable for swimming but not for diving or snorkeling.
- 100 meters (10 ATM): Suitable for swimming and snorkeling but not for high-speed water sports or diving.
- 200 meters (20 ATM): Suitable for all high-impact water sports and some types of scuba diving.
- Diver’s watches: These comply with ISO 6425, which means they are suitable for diving beyond 100 meters.
Is Water Resistance Permanent?
Water resistance is not permanent. The seals and gaskets that provide water resistance can degrade over time due to wear and tear, exposure to chemicals, and changes in temperature.
How Should I Care for a Water-Resistant Watch?
To care for a water-resistant watch, you should:
- Clean it with fresh water after exposure to saltwater or chlorine.
- Avoid exposing it to high temperatures and steam.
- Ensure the crown and pushers are properly sealed after setting the time or date.
Frequently Asked Questions About Waterproofing Watches
Can I Wear My Water-Resistant Watch in the Hot Tub?
It’s not recommended to wear your water-resistant watch in a hot tub. The heat can compromise the seals and gaskets, reducing its water resistance.
How Often Does Water Resistance Need to Be Checked?
Water resistance should be checked annually as part of regular watch maintenance, especially if the watch is frequently worn in water.
How Can I Make My Watch Waterproof?
You cannot “make” a watch waterproof if it was not designed to be so. However, you can maintain its water resistance by replacing gaskets and seals and having it tested regularly.
How Are Watches Made Water Proof?
Watches are made water-resistant through tight seals at potential entry points, such as the case back, crown, and crystal. Gaskets made of rubber, nylon, or Teflon are used, and the materials of the watch are chosen for their resistance to corrosion.
How Do You Use a Waterproof Watch?
Use a waterproof watch within its water resistance limits. After use in water, rinse it with fresh water and dry it with a soft cloth.
How Can I Increase My Water Resistance?
You can’t increase the water resistance rating of a watch, but you can ensure it maintains its existing level by regular servicing and gasket replacements.
How Long Do Watches Stay Waterproof?
The water resistance of a watch can last several years, but it should be tested annually and the gaskets should be replaced every few years or as needed.
Can Water Damage a Watch?
Yes, if water penetrates the seals, it can cause rust and damage the movement and dial.
How Water Resistant Does a Watch Need to Be to Swim?
For swimming, a watch should be rated at least 50 meters (5 ATM), though 100 meters (10 ATM) offers more protection against pressure changes.
What Makes a Rolex Waterproof?
Rolex uses a series of complex seals and a screw-down crown and case back to ensure water resistance. Their Oyster cases are renowned for their durability.
Are All Expensive Watches Waterproof?
Not all expensive watches are water-resistant. Luxury watches prioritize different features, and while many have some degree of water resistance, it’s not a universal trait.
By adhering to these best practices and understanding the capabilities and limitations of your watch’s water resistance, you can confidently wear your timepiece in various environments without fear of water damage. Regular maintenance and care are key to preserving the water resistance of your watch and, by extension, its functionality and aesthetic appeal.
