The true meaning of waterproof and waterproof watches

Let's learn about the difference between waterproof and waterproof watches through the article below!

Waterproof and waterproof: What's the difference?

In the field of watchmaking, the difference between waterproof and waterproof watches often eludes enthusiasts. Although used colloquially interchangeably, these terms reveal distinct characteristics of a watch's durability.

What does waterproof mean?

Waterproof watches : These watches are water resistant to a certain extent, indicating the ability to withstand a certain level of humidity. Every watch, regardless of brand or model, has different levels of water resistance, usually from 1 ATM (10 meters) to 30 ATM (300 meters) and sometimes even exceeds these thresholds.

The terms waterproof and waterproof reveal distinct characteristics of a watch's durability.

What does waterproof mean?

Waterproof watch: On the other hand, a waterproof watch denotes a higher level of water resistance, representing the water resistance of the watch. It suggests that under no circumstances should water be allowed to enter the watch case and penetrate its internal mechanisms. However, it is important to acknowledge that even the most perfect watches undergo gradual deterioration over time due to the natural aging process and prolonged exposure to environmental conditions. hard.

In short, James Bond could use a waterproof watch when he dived to the bottom of the ocean to find a suitcase full of money off the coast of Puerto Rico, while a waterproof watch could be worn by an ordinary person.

Waterproof watches represent a higher level of water resistance.

Maintaining integrity: The role of seals

The integrity of a waterproof or waterproof watch depends greatly on the effectiveness of the seals, which are usually made of rubber or plastic. These seals are instrumental in strengthening the watch's structure, preventing water from penetrating its delicate parts. However, prolonged exposure to extreme temperatures can accelerate gasket deterioration, so regular maintenance, ideally every two years, is required to ensure optimal function.

Decoding the water resistance rating

Although modern watches prominently display water resistance ratings on the caseback, interpreting these figures is not always simple. Contrary to popular belief, specified water resistance does not equate to a watch's safe operating depth in water. For example, a watch that is water resistant to 100m may not be able to sustain prolonged exposure to such depths without risk of damage.

Terms like 'atmosphere' (ATM) and 'bar' act as important metrics, telling you about the watch's resilience to external pressure. ATM, short for atmospheric, represents atmospheric pressure at sea level. In contrast, a bar represents a unit of pressure equivalent to 1 atmosphere. 1 ATM roughly corresponds to 10 meters of water pressure.

Legal framework: ISO standards

To streamline water resistance standards in the watchmaking industry, regulatory bodies such as the International Organization for Standardization (ISO) have produced comprehensive guidelines. ISO 2281, established in 1990, describes rigorous testing procedures including condensation tests, air resistance assessments and water pressure assessments, among others. This standard also prohibits the use of the term 'waterproof' to describe watches.

Building on ISO 2281, the ISO 6425 standard , introduced in 1996, sets strict criteria for watches capable of withstanding depths in excess of 100 meters. These criteria cover a range of tests, including reliability assessments, saltwater resistance assessments and mixed-gas diving protocols, a testament to the comprehensive nature of the standards and commitment to ensure watch reliability in demanding ocean environments.

frequently asked Questions

Can I swim with a waterproof watch?

Yes , you can go swimming with a waterproof watch, but the level of waterproofness determines its suitability for water activities. Watches with higher water resistance ratings, typically measured in bars (BAR), atm (ATM) or meters (m), are designed to withstand immersion in water without damage.

Check its waterproof rating: Make sure your watch is rated for swimming by checking its waterproof specifications. A rating of at least 10 BAR or 100 meters is generally considered suitable for swimming.

Consider water activities: While some waterproof watches are suitable for swimming, others may be specifically designed for diving or high-impact water sports. Understand the intended use of your watch to ensure it meets your needs.

Regular maintenance: Even with a water-resistant watch, maintaining its water resistance is essential. Make sure the seals are intact and the watch is serviced regularly to maintain its water resistance.

Is waterproof better than waterproof?

Although the terms 'waterproof' and 'waterproof' are often used interchangeably, there exists a distinct difference between the two when it comes to watches. 'Waterproof' suggests a higher level of protection against water ingress than 'waterproof'. Waterproof watches are designed to be immersed in water for long periods of time without damage, making them suitable for activities such as diving or deep water swimming. On the other hand, a waterproof watch may be water resistant to a certain degree but may not be completely protected from moisture, making it more suitable for daily wear or light water exposure. This means that in terms of water resistance, waterproof watches offer superior performance and reliability in wet environments compared to waterproof watches.

What does a 50m waterproof watch mean?

A watch labeled '50m waterproof' indicates that it can withstand water pressure equivalent to a depth of 50 meters . However, this does not mean that the watch is suitable for activities such as diving or high-speed water sports. Instead, it suggests that the watch is generally safe for swimming and showering, as well as other daily activities that involve exposure to water. Therefore, although a 50m waterproof watch can withstand swimming and light water exposure, you should avoid exposing the watch to significant water pressure or temperature changes. suddenly if you want the watch to last long.

Can you shower with a 50m waterproof watch?

Taking a shower with a watch that's 50m waterproof might seem reasonable based on its designation, but it's generally not recommended. While the watch can withstand light splashes and short-term exposure to water, such as hand washing, its water resistance does not guarantee protection against water pressure and temperature fluctuations. continuity when bathing. While the 50m rating suggests some degree of water resistance, it's important to exercise caution and avoid submerging the watch underwater during activities such as showering. Continuous exposure to water, soap and steam in a showering environment can compromise the integrity of the watch over time, leading to damage to the watch's internal components.

A waterproof and waterproof watch

Understanding the difference between waterproof and waterproof watches is important to ensure the longevity and functionality of the watch in a variety of environments. Although the term ' waterproof' implies complete waterproofness, it is essential to realize that no watch is completely waterproof. Instead, watches are often labeled as water-resistant, indicating their ability to withstand exposure to water to varying degrees. This distinction is important because the level of water resistance determines the watch's suitability for various water-related activities, such as swimming, showering or diving.
