ToggleOne of the key selling points of Rolex watches is their impressive water resistance. But how waterproof are these iconic timepieces, really?
In this guide, we’ll dive into the technical specifications of Rolex’s water resistance, addressing the question of whether they are truly waterproof or just water-resistant.
Understanding Water Resistance in Watches
Before we get into specifics, it’s essential to understand what water resistance means in the context of watches. Water resistance refers to a watch’s ability to withstand exposure to water without being damaged. It’s often measured in metres, bars, or atmospheres (ATM), with each unit representing a certain depth at which the watch can be submerged without compromising its function.
It’s important to note that no watch can ever be entirely “waterproof” in the strictest sense. Over time, seals wear down, and conditions like temperature changes, wear and tear, and even the force of water can compromise a watch’s water resistance. However, many watches, including Rolex models, are designed to handle everyday exposure to water—whether it’s a quick wash, swimming, or diving.
Rolex’s Commitment to Water Resistance
Rolex’s commitment to water resistance can be traced back to its roots in the 1920s when it became one of the first brands to introduce the concept of a water-resistant wristwatch. The iconic Oyster case, which debuted in 1926, was the first to offer a hermetically sealed design, protecting the watch from dust, moisture, and water. This was a game-changer for the industry, as it allowed wearers to take their watches into the water without fear of damage.
Today, Rolex continues to build upon this legacy with its modern Oyster Perpetual models, which are designed to be highly resistant to water. The watches in this line are equipped with an Oyster case, which is made from a solid block of 904L stainless steel, a highly durable material known for its resistance to corrosion and wear.
Rolex Water Resistance Ratings
Rolex provides specific water resistance ratings for its watches, which help customers understand how well each model can handle water exposure. These ratings are typically measured in metres, with each number indicating the depth at which the watch can be safely submerged without damage. However, it’s crucial to understand that these ratings do not imply you can swim to the specified depth. Instead, they are a measure of the watch’s ability to withstand pressure at that depth.
Here are the water resistance ratings for several popular Rolex models:
Rolex Submariner
The Rolex Submariner is one of the brand’s most famous models and is often associated with diving. It boasts an impressive water resistance of up to 300 metres (1,000 feet). This makes it suitable for recreational diving but not for professional deep-sea exploration.

Rolex Sea-Dweller
For those who demand even more water resistance, the Rolex Sea-Dweller offers a rating of 1,220 metres (4,000 feet), and the newer Rolex Deepsea version extends this to an astonishing 3,900 metres (12,800 feet). These models are specifically designed for professional divers who need a watch capable of withstanding the immense pressure of deep-sea exploration.

Rolex Day-Date and Datejust
While not intended for deep-sea diving, these models are still highly resistant to water. They have a water resistance rating of 100 metres (330 feet), making them suitable for everyday activities like showering, washing hands, or swimming in shallow waters.

Rolex GMT-Master II
The GMT-Master II, a favourite among travellers, also features a water resistance of 100 metres. This model is designed to withstand exposure to water during routine activities, though it’s not built for prolonged immersion.
What to Avoid with Your Rolex
Even though Rolex watches are designed to be highly water-resistant, there are a few conditions where you should exercise caution:
- Hot Water: High temperatures, such as those in a hot tub or steam room, can cause the gaskets to expand, potentially leading to leaks. It’s best to remove your watch before entering any environments with hot water.
- Sudden Temperature Changes: Rapid temperature shifts, such as jumping from a hot bath into cold water, can put pressure on the seals and potentially cause them to crack. This can compromise the watch’s water resistance.
- Saltwater: After exposure to saltwater, it’s crucial to rinse your Rolex with fresh water. Salt can corrode the materials and cause long-term damage to the watch’s case and bracelet.
Look After Your Rolex!
Rolex watches are undoubtedly among the most durable and water-resistant luxury timepieces on the market today. With impressive water resistance ratings and a rich history of innovation, Rolex has earned its reputation as a leader in this field.
While Rolex watches are designed to handle a variety of water-related activities, it’s important to remember that no watch is entirely waterproof. Regular maintenance and cautious use will help you get the most out of your Rolex, ensuring that it continues to perform at its best, even in the water.
Whether you’re diving in the ocean or simply splashing around in a pool, you can trust your Rolex to keep ticking—provided you take care of it and respect its limits.
