How to check water resistance of Seiko Mod Watches

Checking the water resistance of a Seiko Mod Watch is an important step to ensure that your watch maintains its integrity when exposed to water.Here's how you can check the waterproofing of your Seiko Mod Watch:

1. Reference the Water Resistance Rating:

Seiko watches are often labeled with water resistance levels, such as 30 meters (3 ATM), 100 meters (10 ATM), 200 meters (20 ATM), and more.     This rating indicates the depth to which the watch should remain waterproof under certain conditions.

2. Visual Inspection:

Inspect the watch closely for any visible signs of damage, such as cracked crystal, damaged crown, or a loose case back.   Any compromise in the watch's structure can affect its water resistance.

3. Screw-in Crown:

If your watch features a screw-in crown, please ensure that it is securely screwed in.  A properly secured crown helps maintaining the watch's water resistance by preventing water from entering through the crown area.

4. Pressure Testing (Recommend):

The most accurate way to check the water resistance of your Seiko mod watch is to have it pressure-tested by a professional watchmaker. Pressure testing involves sealing the watch in a specialized chamber and subjecting it to controlled pressure changes to simulate underwater conditions.This test will determine whether the watch maintains its water resistance as specified.

5. Home Water Resistance Test (Caution):

While not as accurate as professional testing, you can perform a basic water resistance test at home with caution.

Fill a container with water to a level slightly below the watch's rated water resistance (e.g., if your watch is rated for 100 meters, fill the container to around 30 meters). Gently submerge the watch and observe it for a few minutes.

Pay attention to any signs of water intrusion, such as condensation under the crystal or misting of the dial.

Important Notes:

1. Regular Maintenance:

Keep in mind that water resistance can diminish over time due to wear and tear, aging seals, or exposure to extreme conditions. Regular maintenance is recommended to ensure your watch remains water-resistant.

 2. Avoid Hot Water:

Avoid exposing your watch to hot water, such as hot showers or saunas, as rapid temperature changes can compromise the seals and gaskets.

 

Remember that water resistance is not a permanent feature and requires proper care and maintenance to uphold.  Always exercise caution and refer to your watch's specific water resistance rating to determine its suitability for various water-related activities.
