Are All Rolex Explorer II Watches Waterproof?


When you're considering buying or currently owning a high-end timekeeper like a Rolex Explorer II, you're definitely curious about water resistance and waterproofness. Tips: I recommend you also read about the following topic if you're interested: can you fix a link on a Rolex?

Rolex Explorer II watches are guaranteed to be waterproof up to 10 ATM/100m/300ft. Rolex wrist watches feature water resistance, which is one of their strengths. Rolex invented the first water-resistant wristwatch in 1926, and it has improved on this technology ever since.

Explorer II timepieces are water resistant to a depth of 300ft or 100 meters, according to Rolex SA. Rolex Explorer II watches are appropriate for swimming, but not for diving. The Rolex Submariner is a scuba diving timekeeper with a water resistance of 300m/1000ft.

Hans Wilsdorf, a forerunner in the waterproof model industry, founded Rolex. With his invention, the Rolex Oyster wristwatch, he revolutionised wrist watch water resistance.

Waterproof components are used in the construction of Rolex Explorer II timepieces. Rolex uses a Oyster case on the Explorer II, unlike other brands that use screws to attach their case backs. People concern also wonder about the following: does a Rolex need to be serviced?

The Rolex Explorer II Oyster case compresses the gaskets, hermetically enclosing the wristwatch. Sealing the case produces a higher level of water resistance due to the compression of the gaskets.

Because of their design, Rolex Explorer II wristwatches can be worn in the water. Hans Wilsdorf, the founder of Rolex, was concerned about the wristwatch's resistance to water and dust. To protect a watch movement from moisture and dust, he understood that a dry and airtight case is essential. Visit the dedicated article about Rolex service center san diego for more information.

Hans Wilsford invented and patented a water resistance timepiece case called the Oyster in 1926. The Rolex Oyster watch case is at the foundation of every current Rolex Explorer II. The case is threaded and screwed down like a submarine hatch. For securing the watch movement inside hermetically, gaskets seals are added to the case. This system outperforms screw-in wrist watch cases.

Water-resistant timepieces have traditionally had a weak point in the winding crown. It makes little difference how watertight your model is if the crown stem creates a hole in the case. The opening on the side of the watch case has been a challenge for timekeeper manufacturers. To prevent water from reaching the crown stem, most watchmakers utilise a gasket.

Crown stem holes are the weak part of a timepiece's water resistance. The crown's stem is joined to the movement via a hole in the case's edge. During the continual rotation, winding, and turning of the crown, the crown seal is repeatedly compressed, chafed, and stressed.

The unique Twinlock technology on the Rolex Explorer II provides superior water resistance to the traditional crown gasket. A threaded stem crown is installed in addition to the threaded crown that is screwed into the casing. Rolex's Twinlock mechanism, which combines threaded stems with rubber o rings, improves water resistance. This device compresses many gaskets inside and around the crown stem.

To operate a mechanical model, the crown must be lifted out and rotated. Timepieces that have a weak crown will be less resistant to water. A crown stem has a tube that allows water to enter. After the crown is unscrewed and pulled out, the watch is no longer watertight. Moisture can harm Rolex timepieces. Since the 1960s, the crown has become more resistant to water.

Rolex's modern Explorer II features a patented Twinlock screw down crown with guaranteed waterproof up to 10 ATM/100m/300ft. Explorer II 's twinlock winding crown is equipped with a double waterproofness system. In addition to the tube, the crown also features two sealed zones. The Explorer II 's crown is guaranteed waterproof to 100m(300ft) depth when it is screwed down. The Twinlock provides water resistance that is superior to that of many other watches on the market when the crown is screwed down. As long as they are utilised properly, Rolex Explorer II watches are waterproof up to 100 meters or 300 feet. It's crucial to remember that Rolex Explorer II watertight warranties necessitate regular maintenance and repair.

Swimming With A Rolex Explorer II Top Tips


Ensure that your Rolex Explorer II is still water resistant: If you're going to swim with your Rolex Explorer II, be sure to check that it's still waterproof. Water resistance tests don't include opening the model, so you may complete them without jeopardising your Rolex guarantee. Dry pressure tests are the best means of testing waterproofness. By doing this once a year, you can rest assured that your Rolex Explorer II is still guaranteed waterproof. Another subject people ask themselves is how fast does a Rolex tick?

Avoid exposing the Rolex Explorer II to extreme temperature changes. Temperature fluctuations are not appropriate for the Rolex Explorer II. If you've just come out of a sauna, don't take a cold shower while wearing a Rolex Explorer II. As a result of these extreme temperatures changes, the metal case and the seals are stressed. If exposed to this, watches may lose their ability to withstand water.

Do not put a Rolex Explorer II in contact with harmful chemicals. Perfume and soap, for example, can tarnish or harm the Rolex Explorer II. Contact with aggressive cleaning agents might shorten the life of gaskets. Rolex Explorer II gaskets and water resistance can be damaged by frequent exposure to strongly chlorinated water. In hotels, swimming pools and Jacuzzis use a lot of chlorine.

How Are Rolex Explorer II Watches Water Proof Tested?

How Are Rolex Explorer II Watches Water Proof Tested?


It is important to find out the water resistance level of a watch in order to determine how and where it can be worn safely. Water resistance for the Rolex Explorer II is up to 100m(300ft). The pressures that Rolex Explorer II can withstand while retaining a hermetic seal are used to determine their rating. Water resistance of a timepiece deteriorates over time. You can have your watch tested to find out how water resistant it is. (Another issue to consider is Rolex Datejust with number 045 everrose gold whats it worth?)

Watchmakers check a timekeeper's water resistance using two methods: wet testing and dry testing.

The Dry Test is a modern means of evaluating water resistance by using electronic instruments inside an air vacuum chamber. Only air pressure and digital gauges are used to measure water resistance. But even though the Dry Vacuum Test is more precise than the Wet Test, it cannot determine the exact location of the leak on the wristwatch.

The standard way of assessing water resistance is wet testing. The watch is put to the test with both air and water pressure. Leaks in watch cases can be detected using mechanical pumps and human observation. Although less precise than Dry Testing, the Wet Test can be used to pinpoint the source of a leak.

How Long Will A Rolex Explorer II Last?

In 1910, the first Rolex watch was certified as a chronometer, and the brand has been recognised for precision and accuracy ever since. There are often certain terms associated with this issue, such as best place to buy pre owned Rolex Daytona. A Rolex watch, the Oyster, became the first commercially viable waterproof model in 1926 after it pioneered the technology. Mercedes Glietze tested the patented innovation in 1927, when she wore a Rolex Oyster around her neck as she swam the English Channel. The wrist watch was unaffected and continued to function normally after ten hours in the water.

Rolex revolutionised the watchmaking business in 1931 when it introduced the world's first permanent self-winding mechanism. Most of the brand's models now incorporate this ground-breaking continual movement. The Explorer II was the first self-winding watch with a date indication, and it was debuted in 1945. The Submariner was the first professional diving model with 10 ATM/100m/300ft water resistance. Rolex continues to lead the way with its inventive spirit and innovation in the decades that followed. When the GMT Master was debuted in 1954 by the Swiss company, it was the first wristwatch that allowed pilots to tell time in various time zones at the same time. In 1956, they released the Day-Date watch, which combined the date and day of the week on a single dial.

As an icon of unrivaled quality, innovation, and prestige, the Rolex crown has become an iconic symbol of the brand. Rolex timepieces have been spotted on the wrists of a slew of celebrities throughout the years.

Is The Rolex Explorer II Permanently Waterproof?


Rolex Explorer II watches are frequently thought to be permanently water resistant. The water resistance depth rating of 100 meters or above is a feature that requires maintenance and testing on a regular basis. Editor's note: People should consider the following issue as well: Which Rolex Is Waterproof?

Because many Rolex model owners are unaware of gaskets, they assume their wristwatches will stay waterproof if the rubber gaskets are not replaced. Several Rolex owners may be disappointed by this error. It is critical to keep the gaskets in excellent condition in order for the timekeeper to perform correctly and stay water resistant. You can read more about Rolex second hand does not stop by following the link.

The Rolex Explorer II gaskets are tested before leaving the Rolex manufacture in Switzerland. To ensure the wrist watch is water-resistant, Rolex's laboratory conducts stress tests on both the case and the gasket seals. Testing is carried out beyond the waterproof guarantee's limitations, but on a clean Rolex Explorer II with fresh new gaskets. (If this question interests you, you should also read about the following: What Happens When A Rolex Is Serviced?)

When the gasket seals on the Rolex Explorer II wear out, water resistance may be lost. An old watch's rubber gasket isn't as watertight as a new watch's gasket seal. If you're seeking for information about Rolex Daytona meteorite in particular, you could find it here.

The model must be equipped with gaskets in good condition to be water resistant. Despite being high quality seals, Rolex gaskets deteriorate over time and need to be replaced. It is not unusual for a gasket to be displaced by an impact. Gasket speed of deterioration will primarily depend on how the model is used. A Rolex Explorer II will be more stressed in seawater than one that has never been exposed to saltwater.

Watch gaskets are a vital part of water-resistant Rolex models. To prevent water pressure from entering the Rolex Explorer II, several gaskets surround the crystal, the winding crown, and the case back. The gasket's principal purpose is to act as a water barrier. The most dependable barrier is a model with a strong water resistance.

Rolex's Ultimate Water Resistance


The deepest scuba dive in the world is 534 meters deep. Rolex Sea Dwellers are water-resistant to depths of 1200m/4000ft, whereas the Rolex Deepsea are water-resistant to depths of 3900m/12800ft.

Humans are unable to survive in such depths because of a high level of water pressure. Rolex watches can therefore be considered waterproof.

Rolex presents its Explorer II watch as waterproof up to a depth of 100 meters/330 feet, while its Submariner watch is waterproof up to a depth of 300 meters/1000 feet.

The Rolex Explorer II is water-resistant for what reason?


The standards and history of watch brands in relation to water resistant technology matter a great deal. Even if all watches have the same water resistance rating, the Rolex Explorer II water resistance illustrates that they are not all created equal.

Rolex, the first water-resistant watch company

It has long been the specialty of Rolex to make water-resistant watches. A waterproof and hermetically sealed wristwatch was first invented and produced by Rolex's founder, Hans Wilsdorf, in 1926. Wilsdorf's screw down Oyster concept is used by many Swiss watch brands to create diver watches. Rolex Explorer II watches come with Rolex Oyster cases.

Innovation in water resistance

The water resistance of Rolex Explorer II watches is superior to that of most other brands. Standard on most Rolex models is the Rolex threaded Oyster case.

The screw-down Rolex Explorer II case and crown provide a water-resistant guarrantee of up to 100m/330ft or 10ATM. Rolex Explorer II's threaded twinlock crown is sealed by a second seal for better water resistance.

Water-Resistant Material for Rolex Explorer II

Salt water is extremely corrosive. To protect the watch movement, Rolex uses materials that are rust-resistant. Rolex Explorer II Oystersteel, a material developed by NASA for its high corrosion resistance, is made from grade 904L stainless steel.

Explorer II gaskets are manufactured using fluoropolymers, a special polymer with carbon and fluorine as its main components. In addition to their heat resistance and water inertness, fluoropolymers are not affected by ultraviolet light.

Rolex Explorer II are suitable for swimming


The Rolex Explorer II can be worn while swimming. Due to its water resistance up to 100 meters or 330 feet, the Rolex Explorer II is suitable for swimming.

Tips for swimming in salted water with your Rolex Explorer II

  • If you swimming in the sea with your Rolex Explorer II, make sure to wash it thoroughly with fresh water.
  • Swimming, surfing, sailing, or any individual who wears his or her watch in the water should have their Rolex Explorer II watch tested more frequently.
  • The water resistance of your Rolex Explorer II may be compromised if you drop it accidentally.
  • It is recommended that the Rolex Explorer II be serviced according to Rolex's schedule.
  • Rolex Explorer II must be worn as intended by the manufacturer.
  • Rolex Guideline for your Explorer II should be read and followed.

Rolex Explorer II Water Resistance Cons


  • It is necessary to maintain and service the Rolex Explorer II water resistance.
  • Unless the crown is closed, the Explorer II isn't waterproof.
  • The crown on a Rolex Explorer II watch may not be used in water.

Pros of the Rolex Explorer II water resistance


  • The Explorer II watches by Rolex are water-resistant.
  • Water-resistant Rolex watches have a strong reputation.
  • Rolex Explorer II water resistance is improved by using an Oyster case and Twinlock clasp.
  • Rolex Explorer II watches are water-resistant to 100 meters/330 feet/10ATM.

All Rolex Explorer II are waterproof up to 100m/330ft


It is good to know that all Rolex watches come with a waterproof guarantee of at least 100 meters if you are looking for an expensive Rolex Explorer II watch. In the early 20th century, Rolex founder Hans Wilsdorf pioneered waterproof watches. Watch water resistance was significantly improved by his innovation, the Rolex Oyster. In addition to being water-resistant up to 100 meters, Rolex Explorer II watches also have an Oyster case.

All Rolex Explorer II watches come with a waterproof guarantee of 10 ATM/BAR, or 330 feet/100 meters. The Rolex Submariner and Rolex Deep Sea, however, are even more water resistant. The Rolex Submariner is waterproof to 300 meters, and the Rolex Deep Sea is water resistant to 1200 meters.

Water resistance is a feature of Rolex Explorer II watches for specific reasons. All Rolex Explorer II watches are waterproof thanks to the components they are constructed with. In order for a Rolex Explorer II to be water-resistant, it is equipped with two essential Rolex characteristics:

The Oyster case of the Rolex Explorer II

Unlike many other brands, Rolex uses threaded Oyster cases for its caseback, and screws the watch's element into the middle caseplate. As a result of compression of the gaskets, the Rolex Explorer II Oyster case is hermetically sealed. As the gaskets compress under pressure in the sealed case, more water resistance is achieved.

Rolex Explorer II's Twinlock Crown is designed to maximize water resistance

Watches are most susceptible to water damage at the crown stem hole. Through a hole on the edge of the case, the crown stem is attached to the movement. To adjust the time, the crown must be rotated, wound, and turned continuously, repeatedly compressing, chafing, and stressing the crown seal.

The twinlock crown on the Rolex Explorer II makes it water-resistant. In this system, multiple gaskets are compressed within and all around the crown mechanism. In its screw-down configuration, the Twinlock provides greater water resistance than many other watches on the market.

When maintained properly, the Rolex Explorer II remains waterproof up to 100 meters / 330 feet. It is important to keep in mind that you will need to service and maintain your Rolex Explorer II waterproof guarantee throughout its lifetime.

Rolex Waterproof History


There is no denying the high level of craftsmanship and quality of Rolex watches. Due to their long history, it is no wonder that they have been able to perfect the art of making watches. The headquarters of Rolex are located in Geneva, Switzerland. As Wilsdorf & Davis in 1905, the company began selling watches made by other companies. It started producing wristwatches in 1908 and selling them exclusively to jewelers who would buy at least one dozen per order.

At this point, Rolex was focused on producing high-quality timepieces, which made the name Rolex more than fitting. In order to achieve this, Wilsdorf & Davis began making their watches with new materials and technologies. Several of the innovations would eventually become standard in many watches.

The Rolex company has been innovating at a time when wristwatches were still a novelty. The Oyster watch case was patented by Hans Wilsdorf. Waterproof watches were first introduced by the Oyster watch. Water could not get into this model due to a new airtight seal created by the case.

Wilsdorf's invention was patented in 1926, and it went on to become the basis for many Rolex, Omega, and other watch brands. Before developing the Hermetic watch, Hans Wilsdorf worked on the problem for some years. In spite of the success of the screwdown cap and winding crown, eventually the watch still had to be opened to wind it or adjust its time. Commercial success would be more assured with a crown that screwed into a threaded tube in the watch case. On July 29, 1926, Rolex's oyster trademark was registered

The real-life performance of Rolex's water resistance


The majority of watch brands state their watches are water-resistant, but few have demonstrated their water-resistance in a real situation outside the test lab. Few companies have been able to do this successfully like Rolex.

Swiss watchmaker Rolex consistently shows that its watches are waterproof. Watches produced by Rolex are capable of diving deeper than certified divers because of their high water resistance. One of the prototype Rolex Sea Dwellers survived a 12-thousand-meter underwater dive. When it comes to water resistant watches, Rolex goes above and beyond its competitors by pursuing extreme depth ratings.

Rolex Explorer IIs are guaranteed waterproof up to 100 meters/330 feet because they are made by a manufacturer that is well versed in water resistance. It's the kind of peace of mind you want when buying a high-priced watch.

Rolex Waterproof Oyster case


Among the most iconic features of the Rolex brand is the oyster case. By 1926, the company had developed a waterproof case. For over 90 years, it has served as the backbone of the company's watch production. Everyone from every walk of life will benefit from this accessory. A watch like this is protected from the elements, making it suitable to be worn during physically demanding occupations or activities. As ubiquitous as they are now, oysters serve as a reminder of how well (and for how long) they have done their job.

In 1926, Rolex released its first Oyster watch. Depending on the size, either an octagonal or cushion-shaped case could be ordered, both taking stylistic cues from the Art Deco movement.

Mercedes Gleitze wore one while swimming the English Channel in 1927. Despite 10 hours submerged in ice water, it worked perfectly. The watch was so good that Wilsdorf bought a front page photo of the swimmer and his watch together for the Daily Mail newspaper one month later.

Over the last nine decades, this design has hardly changed. A tube attached to the side of the case has a threaded crown that screws into it. Few years after the Oyster was introduced, the internal spring design was slightly modified to allow for disengagement of the stem as it was screwed down. In contemporary Rolex watches, the crown arrangement consists of about ten different parts and, depending on the type, either creates two sealed zones (Twinlock) or three sealed zones (Triplelock). The case, on the other hand, has significantly advanced. Originally, the movement was not attached directly to the case; this was done with a metal ring, which included the dial and hands as well.


The Oyster watch has evolved over time as Rolex refined its design. Further seals were added in 1953 in order to improve water resistance. As an alternative to a rotating bezel, they introduced a simplified case. As part of their most iconic collection, the Rolex Submariner, Rolex continued to use the water-tight Oyster case.

As early as 1970, a new type of winding crown was introduced with a tube-mounted O-ring seal.

On Rolex's original Sea-Dweller, it was a revolutionary feature, and it is now found on a range of their professional watches, including the Submariner, Daytona, and GMT-Master II.

All Rolex watches - including the dressiest of Explorer IIs and Day-Dates - are water resistant to a depth of 100 meters thanks to their Oyster case and twinlock crown.

One of Rolex's best-selling dive watches is the Rolex Submariner

Recreational diving led to an increase in the popularity of diving watches after World War II. In the 1950s, Rolex Submariner helped to popularize diving watches.

Rolex released one of the first sport watches commercially available at the time: the Submariner. Water-resistant watches were created because of research on commercial divers in deep ocean. Rolex manufacture became determined to achieve this goal. COMEX provided support for experiments in the extreme deep sea as part of its research into diving.

The Submariner is capable of 300m of depth, the Seadweller is 1,220m of depth, and the incredible Deepsea reaches 3,900m of depth.

For nearly a century, Rolex and the sea have inspired each other. ROLEX SUBMARINEER OYSTER PERPETUAL is the ideal watch companion for the scientific adventure of DEEPSEA CHALLENGE.

Rolex has always been synonymous with push the limits of human achievement and discovery, an idea instilled by its creator Hans Wilsdorf.

The 20th century was an exciting period for Hans Wilsdorf as he guided the Rolex company through a period of exploration of the world and big technological advances.


A Rolex watch was also used on the deepest dive in the world, and has proved to be incredibly durable, accurate, and reliable.

Without a doubt, Rolex Oyster cases are among horology's most important innovations. In terms of water resistance for watches, this was a completely new development. Due to Rolex's innovation, timepieces that perform in harsh environments were introduced. It also retained its leading position in a fiercely competitive market.


The Oyster case, first pioneered by Rolex, has become virtually ubiquitous. In modern times, Rolex is recognized as one of the most prestigious brands in water-resistant watches. It is still regarded as a classic example about how simple ideas work best, and even though it has continued to evolve over the years, the industry would look very different today if it weren't for Oyster.
