Are Rolex Waterproof? The Truth About Rolex's Water Resistance

To answer the question “are rolex watches waterproof?”, the answer is technically: no. Rolex watches are water-resistant, not waterproof. 

Models like the Oyster Perpetual can resist water up to 100 meters, thanks to advanced sealing technologies. However, they require regular maintenance to keep their water resistance effective. No watch is completely impervious to water, but Rolex ensures significant protection for everyday use.

This article will discuss the real deal on Rolex’s water resistance. We’ll explain the difference between waterproof and water-resistant Rolex and how models like the Oyster Perpetual stand up to water.

Water-Resistant Watch vs. Waterproof Watches

This table demystifies the capabilities and limitations of Rolex watches versus the misconceptions of Rolex watches waterproof.


Water Resistant 

Waterproof Watches

Depth Rating

Indicates the maximum depth at which a watch is guaranteed to resist water pressure, e.g Rolex Oyster Perpetual models are rated up to 100 meters.

Misapplied in the context of watches; true waterproofing is not possible as per the industry standards.


Essential for preserving water resistance capabilities, including periodic seal checks and replacements.

The concept of a maintenance-free, waterproof watch is unrealistic; all water-resistant watches require upkeep.


Appropriate for daily wear and specific water activities within the limits of their depth rating.

Misleadingly implies that watches can be used under any water-related condition without risk.

Materials & Design

Employs seals, gaskets, and other design features like screw-down crowns to protect against water entry.

The notion of materials that can achieve absolute waterproofing in watches is debunked by the article.


Watches are often ISO certified for water resistance, demonstrating they meet stringent international standards.



Subject to rigorous pressure and water ingress tests to ensure they adhere to their stated water resistance.

The concept of testing for waterproofing is incorrect; tests are for water resistance levels.


Over time, water resistance can decrease due to wear and tear. Watches are not designed for indefinite underwater use.

Expecting no limitations in water exposure is a misunderstanding; all watches have their resistance limitations.

In a nutshell, water resistance in watches, such as the 100-meter rating of Rolex Oyster Perpetual models, indicates a watch’s ability to withstand water pressure to a certain depth, not an absolute immunity to water. 

The term “waterproof” is a misnomer in watchmaking, as true waterproofing is unattainable with current technology. Regular maintenance, including seal checks and replacements, is crucial to sustain a watch’s water resistance.

The Evolution of Rolex’s Water Resistance Watch

The Evolution of Rolex's Water Resistance Watch

Since its founding by Hans Wilsdorf in 1905, Rolex’s journey has been marked by innovation, particularly in water resistance. Wilsdorf aimed to craft reliable, accurate Rolex models, but achieving true waterproofness posed significant challenges, primarily due to dust and moisture infiltration through the winding crown.

  • 1926: Rolex introduces the Oyster case, the world’s first water-resistant watch case.
  • 1953: Rolex releases the Oyster Perpetual Submariner, water-resistant to 100 meters (330 feet).
  • 1954: The Submariner’s water resistance increases to 200 meters (660 feet).
  • 1967: Launch of the Sea-Dweller, water-resistant to 610 meters (2,000 feet), and later to 1,220 meters (4,000 feet) with the introduction of a helium escape valve.
  • 1978: The Sea-Dweller 4000 is introduced, extending water resistance to 1,220 meters (4,000 feet).
  • 1989: The Submariner receives an upgrade, now with a water resistance of 300 meters (1,000 feet).
  • 2003: The 50th-anniversary Submariner, nicknamed ‘Kermit‘ for its green bezel, is introduced.
  • 2008: Rolex unveils the Rolex Deepsea, rated for a depth of 3,900 meters (12,800 feet) with a Ringlock system for extreme underwater exploration.
  • 2012: The Deepsea Challenge experimental watch descends to 10,908 meters (35,787 feet). 

The Deepsea Challenge’s legacy is intertwined with filmmaker James Cameron’s historic dive to the Mariana Trench 2012. An experimental version of the watch accompanied Cameron to the Challenger Deep, the deepest point in the ocean.

  • 2014: The Sea-Dweller 4000 model is re-released with updated features like the Cerachrom bezel and improved luminescence.
  • 2017: Rolex introduces the Sea-Dweller Ref. 126600, in commemoration of the model’s 50th anniversary, with a larger 43mm case and water resistance to 1,220 meters (4,000 feet).

Understanding Rolex’s Depth Ratings

Understanding Rolex's Depth Ratings

Watches are tested under ideal conditions, but real-life conditions bring variables like movement and aging gaskets, which can affect water resistance ratings.

  • ‘Meters’ is the direct measurement of depth that Rolex uses, conveniently converted alongside its feet equivalent for easy understanding.
  •  ‘ATM’ refers to atmospheres, where 1 ATM is the pressure found at 10 meters below the surface – a handy comparison for gauging water resistance. 
  • Lastly, ‘Bar’ aligns closely with ATM, frequently used in discussions about pressure, such as filling Scuba tanks, though it’s less commonly seen on watch dials. 

Here’s a quick rundown of what to expect from your watch’s water resistance rating:

  • 30m (100ft, 3 Bar, 3 ATM): This is your basic rainproof rating. Perfect for everyday wear, it’ll survive hand washing and the odd splash, but it’s best to leave it on dry land when you hit the pool.
  • 50m (165ft, 5 Bar, 5 ATM): Taking it up a notch, this rating says “yes” to swimming but “no thanks” to anything more intense like jet skiing or dive bombing into the pool. Light swimming is on the cards, but that’s your lot.
  • 100m (330ft, 10 Bar, 10 ATM): This rating is cool for swimming and snorkeling, but hold off on the high board diving. It’s technically okay as a Scuba diving watch, provided those gaskets are fresh.
  • 200m (660ft, 20 Bar, 20 ATM): Welcome to the Scuba zone. If your watch boasts this rating, you’re good for diving and even some high-impact water sports. It’s the go-to for underwater adventurers.
  • 300m and above (1,000ft, 30 Bar, 30 ATM): The sky (or should we say, the ocean floor) is the limit with this rating. Ideal for all water sports and deep diving, except for the most extreme forms of saturation diving. For the pros and the thrill-seekers.

Rolex’s Special Models: Sea Dweller & Deepsea

Rolex's Special Models: Sea Dweller & Deepsea

Rolex’s Sea-Dweller and Deepsea models are the heavyweights of the diving world. The Sea-Dweller, with a depth rating of 1,200m, and the Deepsea, capable of reaching a staggering 3,900m, are engineered for the most demanding underwater missions.

Besides their impressive depth ratings, the helium escape valve sets these models apart. This genius feature allows gases that have infiltrated the watch during deep dives to escape safely during decompression, preventing damage to the watch. 

The Twinlock and Triplock systems play pivotal roles in reinforcing the water resistance of Rolex watches, each tailored to different water exposure levels.

Twinlock Crown System:

  • Utilizes two sealed zones for water resistance: one within the crown’s tube and another inside the crown.
  • Serves non-chronograph models like the Datejust, Day-Date, and Explorer series, supporting up to 100 meters (330 feet) water resistance.
  • Identified by two dots or a line under the Rolex coronet on the crown for stainless steel models, and a single dot for gold or two-tone models.

Triplock Crown System:

  • Adds an extra seal, totaling three: inside the tube, inside the crown, and around the winding tube’s thread.
  • Equips Rolex’s high-end dive watches such as the Deepsea and Submariner, enhancing their water resistance for deeper dives.
  • Recognizable by three dots beneath the Rolex coronet, indicating its enhanced sealing capability suited for rigorous underwater conditions.

Maintaining Your Rolex’s Water Resistance

Maintaining the water resistance of your Rolex requires vigilance against various threats that can compromise its integrity. Factors such as wear and tear, impacts, improperly sealed crowns, drastic temperature fluctuations, exposure to chemicals, the corrosive effects of saltwater, pressure changes, and inadequate servicing can all breach its defenses.

Routine Care and Maintenance

While these timepieces boast impressive water resistance, a bit of TLC goes a long way to keep them in shipshape. 

Here’s how to avoid common pitfalls:

  • Watch Out for Heat: Saunas, hot tub and shower, or a day in the sun might sound relaxing to you, but your Rolex might beg to differ, especially the gasket. This rubber ring seals the deal against water, and too much heat can warp it out of shape. 
  • Vintage Vibes: Vintage Rolex watches have tons of character, but they might not hold up in water like they used to. Time isn’t kind to gaskets, and those old seals might not be as tight as they once were. If you’ve snagged a vintage watch beauty, get it checked by an authorized dealer to ensure it’s still ready to dive.
  • Stick to the Originals: Rolex watches undergo a barrage of tests to ensure they’re up for anything. Swapping out parts for aftermarket alternatives? That’s a gamble on your watch’s integrity. Keep it original to keep it tight.
  • Crown Check: It’s easy to overlook, but leaving the crown unscrewed is like leaving the door open in a rainstorm. Even the sturdiest Oyster cases can’t fend off water if the crown’s hanging loose.

Servicing Intervals

Just like your car needs its regular oil changes and your house its yearly spring cleaning, your Rolex demands its own kind of maintenance to keep ticking beautifully and, importantly, stay water-resistant. Regular servicing isn’t just a suggestion; it’s a cornerstone of Rolex care. 

So, when does your Rolex need this essential TLC? The general recommendation is every 5 to 10 years, but this can vary based on your watch’s age, model, and how you wear it. If you’re a diving enthusiast or your Rolex sees a lot of action, you might want to lean towards the shorter end of that spectrum.


1. Is it OK to swim with Rolex?

Yes, it is generally okay to swim with a Rolex, especially if the watch is a modern model designed with significant water resistance capabilities. Rolex models like the Submariner, Sea-Dweller, and Deepsea are specifically designed for underwater use, including swimming and diving. However, it’s important to ensure the crown is fully screwed down and that the watch’s water resistance is up to date with regular maintenance checks.

2. Can I wear my Rolex in the shower?

While Rolex watches are built to withstand water, wearing your Rolex in the shower is not recommended. The combination of hot water, steam, and soap can degrade the watch’s rubber gaskets and reduce its water resistance over time. It’s better to err on the side of caution and remove your Rolex before showering.

3. What happens if a Rolex gets wet?

If a Rolex gets wet under normal circumstances (e.g., hand washing, rain), nothing should happen if the watch is in good condition and has been properly maintained. Rolex watches are designed to be water-resistant and can handle exposure to water. However, if water penetrates the case due to worn seals or an improperly secured crown, it can cause damage to the movement and internal components.

If you suspect water has gotten inside your watch, it’s crucial to have it checked by a professional as soon as possible.

4. Which Rolex models are waterproof?

No Rolex models are advertised as “waterproof,” but many are water-resistant to varying depths. Rolex uses the term “water-resistant” to more accurately describe their watches’ capabilities. Here are some examples:

  • Rolex Submariner: Water-resistant up to 300 meters (1,000 feet), designed for diving.
  • Rolex Sea-Dweller: Water-resistant up to 1,220 meters (4,000 feet), suitable for deep-sea diving.
  • Rolex Deepsea: Water-resistant up to 3,900 meters (12,800 feet), designed for extreme underwater exploration.

It’s important to note that water resistance is not a permanent condition and can be affected by wear and tear, age, and shocks. Regular maintenance is necessary to ensure the integrity of the water resistance over time.

Final Word

Understanding and properly caring for your Rolex water resistance capabilities is not just about preserving a piece of precision machinery; it’s about cherishing a legacy. Whether navigating the depths of the ocean or the complexities of daily life, a Rolex is more than a watch—it’s a companion through life’s adventures, big and small.

Key Takeaways

  • Understanding the distinction between “waterproof” or “water resistant” is more than a matter of semantics—it’s essential knowledge for any Rolex owner.
  • Rolex watches, renowned for their robustness, offer varying degrees of water resistance, from the Oyster Perpetual’s 100 meters to the awe-inspiring 3,900 meters of the Deepsea models.
  • Proper care and regular maintenance are paramount in maintaining a Rolex’s water resistance.
