Waterproof vs. Water-Resistant: What Rolex Owners Need to Know
One of the most frequent questions watch buyers ask is whether a particular model is "waterproof" or "water-resistant." While it might seem like splitting hairs, the difference is significant—especially given how carefully watch brands must choose their wording. If you're wearing a Rolex right now, it's helpful to know exactly what these terms mean and how Rolex handles the distinction.
Understanding the Terminology: Waterproof vs. Water-Resistant
'Waterproof' implies that a watch is completely impervious to water under any circumstances, suggesting that it will remain unharmed regardless of the depth or duration of water exposure. However, this term can be misleading because no watch is entirely immune to water pressure indefinitely, especially under extreme conditions. Recognizing this, the Federal Trade Commission (FTC) banned the term 'waterproof' in advertising for watches in the 1960s.
The FTC found the term potentially misleading, as no product can guarantee complete imperviousness to water in all conditions. As a result, most watch brands now use "water-resistant" to describe their products, offering a more accurate representation of what consumers can expect.
Rolex, however, occupies a bit of a gray area here. While other brands strictly adhere to FTC guidelines, Rolex continues to occasionally use "waterproof" in their marketing, largely due to historical precedent dating back to their first waterproof Oyster model from 1926.
A Brief History: Rolex and the Invention of Waterproof Watches
Rolex is a brand known for luxury and innovation, and they are famous for developing highly-water-resistant watches. In 1926, Rolex introduced the Oyster, which was the world's first "waterproof" wristwatch, as described by Rolex. The watch had a hermetically sealed case, making it resistant to dust, dirt, and most importantly, water. To demonstrate its effectiveness, Rolex famously tested the Oyster by attaching it to the swimmer Mercedes Gleitze during her attempt to swim across the English Channel. After more than 10 hours in the water, the watch emerged in perfect working condition, solidifying Rolex's reputation for durability and precision.

To this day, Rolex continues to use 'waterproof' in its branding. This places them in a gray area, as they ostensibly use the term in reference to their historical marketing (at least in America), while other brands strictly comply with the FTC’s regulations. It's worth noting that Rolex tests their professional models to 25% more than their ratings with both positive and negative pressure. They test their non-professional models to 10% more than their ratings with both positive and negative pressure.
What Does Water-Resistant Really Mean?
When you see a watch labeled as "water-resistant," here's what those numbers typically mean (although there's variance across brands):
30 Meters (3 ATM): Splash-proof. Suitable for everyday use, including washing hands or getting caught in the rain, but not for swimming.
50 Meters (5 ATM): Can handle light water activities, such as showering or swimming in shallow water, but not suitable for diving.
100 Meters (10 ATM): Safe for swimming, snorkeling, and recreational scuba diving.
200 Meters (20 ATM) or more: Suitable for professional marine activities, diving, and high-impact water sports. Watches with this rating are designed to withstand deeper water pressure.
What You Should Know About Caring for Your Water-Resistant Watch

Even if your watch has a high water-resistance rating, it's essential to take proper care of it to maintain its performance. Over time, seals and gaskets that keep water out can degrade, especially if exposed to saltwater or chlorine. Regular maintenance and pressure testing by a professional are crucial to ensure that your watch remains water-resistant.
Additionally, you should refrain from manipulating your watch's crown or pushers while it's submerged in water, as this can compromise its water resistance.
The Final Verdict: Is Your Watch Waterproof or Water-Resistant?

If you're wearing an Oyster-cased Rolex, you're wearing one of the most reliably water-resistant watches available, but it still isn't truly "waterproof." Rolex watches, like all high-quality watches, require proper maintenance and sensible care to maintain their water-resistant properties.
Ultimately, knowing the difference between "waterproof" and "water-resistant" isn’t just semantics—it’s about taking proper care of your timepiece. Understanding these nuances ensures your watch remains reliable, whether you're diving into the ocean or just caught in the rain.
