Water Resistance Ratings Explained: A Deep Dive into La Touraine's Homage, Tachymeter, and Dive Watches

When choosing a watch, the term water resistance ratings explained often pops up, but what does it actually mean for your timepiece? This blog post dives into the specifics of water resistance ratings, detailing what each rating signifies and how it impacts your watch's ability to handle water. 

We'll explore the differences between being splash-resistant and suitable for diving, ensuring you know precisely what your watch can withstand. Additionally, we'll highlight La Touraine’s exceptional collections, recognized for their superior water-resistant capabilities. Whether you’re wearing your watch for daily activities or special underwater adventures, understanding these ratings is key to choosing a watch that meets your needs and lasts through your experiences

Water Resistance Ratings Explained

When considering a watch that can handle everything from splashes to deep-sea adventures, understanding water resistance ratings is key. This discussion explains two major standards: the IP rating and ISO 6425, which ensure your watch meets your lifestyle needs.

IP Rating

The IP (Ingress Protection) rating helps gauge how well a device, including watches, stands against solid and liquid entry. This rating is crucial for determining how your watch will perform when exposed to everyday elements. For water resistance, IP ratings describe protection levels ranging from IP55, which guards against limited dust and low-pressure water jets, to IP67, offering complete dust resistance and immersion protection up to 1 meter deep for 30 minutes. While these ratings provide a baseline, they mainly cover scenarios involving minimal water contact.

ISO 6425

For those who dive deeper, ISO 6425 is the go-to standard. Established by the International Organization for Standardization, this norm dictates that watches must withstand much more than superficial contact with water. ISO 6425-certified watches are tested to endure at least 100 meters of water pressure, with many models rated for 200 meters or more. This makes them suitable for professional-grade diving, where exposure to significant depths and pressures is a given.

La Touraine’s Water Resistance Rating

At La Touraine, we rely on the ISO 6425 standard to ensure our watches offer superior water resistance. This commitment means our customers can confidently wear their watches in a range of aquatic environments, from swimming pools to oceanic depths.

What Is a Good Water Resistance Rating?

Understanding what constitutes a good water resistance rating is essential for anyone looking to maintain their watch in top condition, especially when exposed to water. Whether you’re an everyday wearer or a professional diver, knowing these ratings can greatly influence your choice of watch.

IP Rating

The IP (Ingress Protection) rating is critical for determining how well your watch can resist entry of solids and liquids:

  • IP65: Protects against dust ingress and low-pressure water jets from any direction.
  • IP67: Fully dust tight and can handle temporary immersion in water up to 1 meter for 30 minutes.
  • IP68: Completely dust tight and protects against long periods of immersion under higher pressure, specific conditions provided by the manufacturer.
  • IP07: Offers no dust protection but can withstand immersion up to 1 meter for 30 minutes.
  • IP08: Similar to IPX7 but allows for continuous underwater use beyond 1 meter under conditions specified by the manufacturer.

These ratings ensure that everyday activities involving water are less likely to damage your timepiece.

ISO 6425

For deeper water activities, ISO 6425 ratings provide a more specific guideline:

  • 100m (10 ATM): Good for swimming, snorkeling, and water sports, withstands submersion up to 1m.
  • 200m (20 ATM): Suitable for recreational scuba diving up to 40m, offering greater depth tolerance.
  • 300m (30 ATM): Ideal for serious water sports and diving activities, designed for significant depths and prolonged exposure.

These standards are specifically tailored for watches that require rigorous water resistance, ensuring they function optimally even under challenging conditions.

Both IP and ISO 6425 ratings address different needs. While IP ratings cover general and minimal water exposure, ISO 6425 is dedicated to the needs of those engaging in extensive underwater activities. Knowing these distinctions helps in selecting a watch that not only matches your aesthetic but also meets your practical requirements.

Why Water Resistance Ratings Matter in Watches

Water resistance ratings in watches are crucial for ensuring the longevity and functionality of a timepiece under various moisture conditions. These ratings indicate how well a watch can withstand exposure to water, crucial for everyday wear and special activities. Even routine exposure to water, like rain or handwashing, can damage a watch without adequate protection.

For enthusiasts involved in water sports or who frequent aquatic environments, a higher rating is necessary to guard the intricate internal mechanisms against water ingress. Accurately understanding these ratings helps buyers select a watch that suits their lifestyle, preventing water damage and maintaining the watch’s precision and reliability.

Water Resistant Vs. Water Repellent Vs. Waterproof

Understanding the differences between water resistant, water repellent, and waterproof ratings in watches is crucial for choosing the right watch for your needs.

Water Resistant

Water-resistant watches are designed to withstand minor water exposure, such as raindrops or splashes from hand washing. They are not intended for prolonged submersion. Manufacturers achieve this by using tight seals which offer a basic level of protection against water ingress. These watches typically suit everyday use where significant water contact is unlikely.

Water Repellent

Water repellent watches go a step further by incorporating materials that actively repel water. This means they can handle slightly more water exposure compared to water-resistant models. The treatment often involves coatings that repel water on the surface, thus enhancing the watch's ability to keep water out. These watches are suitable for swimming but not for diving or prolonged submersion.


The term waterproof suggests that the watch can be submerged in water without the risk of water entering the internal mechanism. However, true waterproofing is subject to specific limitations, which are usually defined by the IP rating of the device. For instance, an IP68 rating indicates the watch can handle continuous submersion in water to a certain depth, often around 1.5 meters, for a specific period. Waterproof watches are ideal for swimming and diving, depending on their rated depth.

How To Maintain and Care for Water Resistant Watches

Caring for water-resistant watches is essential to ensure they maintain their functionality and longevity, even if they are designed to withstand exposure to water. Here are some practical tips on how to maintain and care for your water-resistant timepieces:

  • Avoid Crown Compromise: Never pull out the watch’s crown when the watch is submerged or even when it is wet. This can compromise the seal and allow water to enter the mechanism.
  • Wipe After Exposure: Always dry your watch with a soft cloth after exposure to water. This helps prevent the buildup of salt, chlorine, or other residues that could corrode the seals.
  • Regular Checks: Have the water resistance of your watch checked annually as seals can degrade over time due to wear and normal aging.
  • Rinse After Swimming: If you swim in the ocean, rinse your watch in fresh water afterward. Salt can be corrosive and damage the water resistance integrity.
  • Avoid Extremes: Keep your watch away from extreme temperatures and environments that could affect its water resistance, such as saunas or hot showers.

By following these simple care steps, you can help ensure that your watch continues to function effectively and remains in good condition, preserving its water resistance ratings for years to come.
