How to know if your watch is really waterproof? Complete guide

Watch water resistance is a crucial topic for any watch enthusiast. Whether you’re a seasoned diver or simply concerned about protecting your precious timepiece from everyday splashes, understanding the water resistance of your watch is essential. In this article, we’ll dive into the depths of this topic to help you determine if your watch is truly waterproof.

Understanding Waterproofing Levels

Before you can determine if your watch is waterproof, it's important to understand what the different levels of waterproofing actually mean.

What do the indications on the dial mean?

You've probably noticed inscriptions like "30M", "50M" or "200M" on the dial of your watch . But be careful, these numbers can be misleading!

• 30M (3 ATM) : Splash resistant, but not suitable for swimming.
• 50M (5 ATM) : Suitable for surface swimming, but not for diving.
• 100M (10 ATM) : Suitable for snorkeling.
• 200M (20 ATM) and above : Suitable for scuba diving .

It is crucial to note that these indications do not correspond to the actual depth to which the watch can be submerged. In reality, they represent the pressure that the watch can withstand in laboratory conditions.

How to test the water resistance of your watch?

Now that we have clarified the levels of waterproofness, let's see how you can check if your watch is really waterproof.

1. Check the gaskets : Carefully examine the gaskets around the crown and case back of the watch. Good gaskets are essential to maintaining water resistance.
2. Test the crown : Make sure the crown is screwed in tightly (if it is a screw-down crown ). A poorly closed crown is the main cause of water infiltration.
3. Look for condensation : If you notice condensation inside the glass of your watch , this is a clear sign that the water resistance is compromised.
4. Get a professional test : The safest way is to have your watch tested by a professional watchmaker . They use specialized machines to check for water resistance under pressure.
5. Use a homemade waterproof tester : For DIY enthusiasts, there are waterproof watch testing kits available in the market. However, be careful as improper use could damage your watch.

Factors affecting waterproofing

The water resistance of a watch is not a permanent characteristic. Several factors can affect it over time:

• Age : Gaskets naturally wear out over time.
• Temperature : Extreme temperature variations can affect seals.
• Impact : Strong impact may deform the housing or seals.
• Chemicals : Exposure to certain products (chlorine, soap) can damage the seals.

To maintain the water resistance of your watch, it is recommended to have it checked every 12 to 18 months by a professional. This is especially important if you regularly dive with your watch .

Tips for maintaining the water resistance of your watch

Maintaining the water resistance of your watch is as important as checking it. Here are some tips to preserve this essential feature:

1. Rinse with fresh water : After swimming in the sea or pool, rinse your watch with fresh water to remove salt or chlorine.
2. Avoid sudden temperature changes : Do not go directly from a hot bath to a cold pool, as this can cause the metal to contract and affect the seals.
3. Do not operate the crown underwater : Even if your watch is water-resistant, avoid operating the crown or pushers while submerged.
4. Store your watch properly : When you are not wearing it, keep your watch in a suitable case to protect it from humidity and dust.
5. Perform regular maintenance : Regular maintenance of your watch by a professional will not only ensure its water resistance, but also its longevity.

Water resistance is a crucial feature of your watch, whether it’s a high-end dive watch or a stylish automatic watch . By understanding the different levels of water resistance, performing regular checks, and taking care of your watch, you can ensure that it stays true to its job whether you’re swimming with dolphins or simply washing your hands.

Remember that every watch is unique and its capabilities may vary. If you have any doubts about the water resistance of your watch, it is always best to consult a professional watchmaker . After all, prevention is better than cure, especially when it comes to protecting your precious timepiece!

FAQ: Everything you need to know about watch water resistance

Q1: Is my watch really water resistant to 30 meters?

A: No, a watch marked "30M" is generally not designed to be submerged to a depth of 30 meters. This indication means that it can withstand light splashes or rain, but it is not suitable for swimming or diving.

Q2: Should I have my watch's water resistance checked if I never swim with it?

A: Yes, it is recommended to have your watch's water resistance checked regularly, even if you don't use it in water. Water resistance protects your watch not only from water, but also from moisture and dust in daily use.

Q3: Can I use my automatic watch in a winder if it is not perfectly waterproof?

A: Yes, you can use a watch winder for your automatic watch even if it is not perfectly waterproof. Watch winders do not involve exposure to water or excessive humidity.

Q4: How do I know if my watch needs a new gasket?

A: It is difficult to determine without a professional test. However, if you notice fogging under the glass or your watch is more than 2-3 years old without checking, it is time to have its gaskets checked by a watchmaker.

Q5: Are smartwatches as waterproof as traditional watches?

A: It depends on the model. Some smartwatches are as waterproof as traditional watches, or even more so. However, it is important to check the manufacturer's specifications as waterproof levels can vary considerably between different smartwatch models.
