Why It Matters
The Rolex Submariner is celebrated for its legendary water resistance, making it the ultimate dive watch. However, seals, gaskets, and other components wear out over time, potentially compromising its watertight integrity. Regular water resistance testing is essential to ensure your Submariner remains safe for underwater adventures and everyday use. Skipping this step could lead to costly water damage and affect the longevity of your prized timepiece.
TLDR - Quick Guide
- Purpose of Water Resistance Testing: Verifies that the watch can withstand pressure without leaks.
- When to Test: Annually, or after impacts, service, or exposure to extreme conditions.
- Testing Methods: Dry pressure testing and wet immersion testing.
- Cost: $50–$150, or included in full servicing.
- Professional Testing Only: DIY testing is risky and unreliable.
Detailed Breakdown
1. What is a Water Resistance Test?
A water resistance test evaluates your Rolex Submariner’s ability to remain watertight under various pressure levels.
Key Components Tested:
- Gaskets: Ensure seals around the caseback, crown, and crystal are intact.
- Crown System: Checks for wear or damage in the screw-down crown mechanism.
- Case Integrity: Verifies that the case is free from cracks or warping.
2. When Should You Test Your Submariner’s Water Resistance?
- Annual Maintenance: Routine testing ensures gaskets and seals remain effective.
- After Impact: A hard knock can loosen components or compromise seals.
- Post-Service: Always request a water resistance test after servicing to confirm the watch has been resealed correctly.
- Before Diving: Testing is essential before exposing your Submariner to significant water pressure.
3. Water Resistance Testing Methods
Dry Pressure Testing
- Involves placing the watch in a sealed chamber and increasing air pressure.
- Sensors detect changes in the case’s shape to identify leaks.
- Advantages: Non-invasive and doesn’t expose the watch to water.
Wet Immersion Testing
-
Combines air pressure with water to check for leaks under real-world conditions.
-
Bubbles indicate where water is entering the watch.
-
Advantages: Simulates actual diving conditions, ensuring accuracy.
-
Pro Tip: Most service centers use a combination of dry and wet tests for the most reliable results.
4. Costs of Water Resistance Testing
- Standalone Testing: $50–$150 at a professional watchmaker or authorized Rolex service center.
- Included in Full Service: Water resistance testing is part of the standard Rolex servicing package, which costs $800–$1,200.
5. Why DIY Water Resistance Testing is a Bad Idea
- Lack of Equipment: Professional testing requires specialized chambers and sensors.
- Risk of Damage: Improper testing can damage seals, gaskets, or even the movement.
- Unreliable Results: DIY methods can’t replicate the precise conditions needed to ensure watertight integrity.
6. Tips to Maintain Your Submariner’s Water Resistance
- Keep the Crown Secured: Always screw the crown tightly before exposing the watch to water.
- Avoid Extreme Conditions: Rapid temperature changes or deep impacts can affect seals.
- Regular Servicing: Replace gaskets and seals as part of routine maintenance.
- Rinse After Saltwater Use: Salt can degrade seals over time if not washed off.
Key Takeaways
- Regular water resistance testing ensures your Rolex Submariner remains watertight and dive-ready.
- Annual testing, or testing after impacts and servicing, is essential for maintaining functionality.
- Costs range from $50 to $150, with testing often included in full service packages.
- Professional testing is the only reliable way to verify water resistance; DIY methods should be avoided.
- Proper maintenance, including gasket care and crown security, helps preserve water resistance.
