Is Rolex Datejust waterproof?

All Rolex Datejust Are Water Resistant Watches

When you are about to buy or already own a Rolex Datejust, you probably want to know about water resistance and waterproofness. The fact is, no watch can guarantee to be 100% waterproof; therefore, no watch is truly waterproof. Rolex Datejust is a water resistant watch guarantee waterproof up to 100m/330ft. You can swim with a Rolex Datejust. The watch waterproof guarantee up to 100 meters or 330 feet, makes the Rolex Datejust adequate for swimming.

Why Are Rolex Datejust Watches Waterproof Guarantee Up To 100M/330Ft

When many people ask themself should I buy a Rolex Datejust, water resistance is a good question to ask. If you are in the market for an expensive Rolex Datejust watch, it is good to know that all Rolex Datejust are water resistant with a waterproof guarantee of at least 100 meters. Hans Wilsdorf, the founder of Rolex, was a pioneer in waterproof watches. His innovation, the Rolex Oyster watch, was a significant improvement for watch water resistance. All the Rolex Datejust models are equipped with an Oyster case that makes them water resistant up to 100m depth.

The standard for Rolex Datejust watches is a waterproof guarantee up to 10 ATM/BAR, 330 feet/100 meters depth rating. However, Rolex diving watches have even higher water resistance: The Rolex Submariner has a 300 meters water resistance, and the Rolex Deep Sea has a record 1200 meters water resistance.

Reasons why Rolex Datejust are water resistant watches

There are specific reasons why Rolex Datejust watches are water resistant. Rolex Datejust watches are built with components that make them waterproof. Water resistance on a Rolex Datejust is provided by two essential factors unique to the Rolex watch brand:

The Rolex Datejust Oyster Case

When many other brand use case backs attached with screws, the Rolex Datejust has a threaded Oyster case that screw down the element of the watch on the middle case. The Rolex Datejust Oyster case compresses the gaskets to hermetically seal the watch. The compression of the gaskets when the case is sealed produce a higher level of water resistance.

The Rolex Datejust's Twinlock Crown

The weakest part of a watch water resistance is the crown stem hole. The stem of the crown is attached to the movement through a hole in the case edge. The crown seal is repeatedly compressed, chafed, and stressed as the crown is constantly rotated, wound, and turned to correct the clock.

Rolex Datejust are water resistant because they have a threaded Twinlock crown. This system compresses multiple gaskets inside and around the crown stem. When the crown is screw down, the Twinlock provide water resistance above and beyond many other watches on the market. On the question of why are Rolex Datejust watches so expensive? This element plays a factor.

As long as the Rolex Datejust is used properly, the watch will remain waterproof up to 100 meters / 330 feet. But keep in mind that the Rolex Datejust waterproof guarantee will need servicing and maintenance during the lifespan of the watch.

  • You should have your watch tested more frequently if you are a diver, swimmer, surfer, sailor, or individual who regularly wears their watches in the water.
  • Accidentally dropping your Rolex Datejust can compromise its water resistance.
  • It is essential to wash a Rolex Datejust with fresh water after wearing it in the sea, whether diving or just splashing.
  • It is important to follow Rolex's recommended servicing schedule for the Rolex Datejust.

Rolex's Water Resistant Watches

Watch brands' standards and history relating to water resistance technology matter a great deal. Rolex Datejust water resistance illustrates that not all watches are created equal, even if they all have the same water resistance rating.

Water resistance pioneer

Waterproof watches have long been the expertise of Rolex. In 1926, Rolex's founder Hans Wilsdorf invented and manufactured the first waterproof and hermetically sealed wristwatch called the Rolex Oyster. Many Swiss watch brands use Wilsdorf's screw down Oyster concept for their diver watches. Rolex Datejust have a Rolex Oyster watch case.

Water resistance innovation

Rolex Datejust watches have features that make their water resistance superior to many other brands. Rolex threaded Oyster case is standard on most Rolex models.

The Rolex Datejust screw down case and crown provide a waterproof guarantee of up to 100meters/330feet or 10ATM. A second gasket seals around the Rolex Datejust threaded twinlock crown to ensure better water resistance.

Rolex Datejust Water Resistant Material

Salted water is very corrosive. Rolex Datejust use materials that a highly rust resistant to protect the watch movement. Rolex Datejust Oystersteel is a grade 904L stainless steel developed by NASA for its anti-corrosion performance.

Rolex Datejust gaskets are made of fluoropolymers, a group of high performance polymers consisting of carbon and fluorine. Fluoropolymers have excellent resistance to heat degradation, do not absorb water and are unaffected by ultraviolet light.

About Waterproof Watches

Waterproof watches do not exist because the definition of waterproof implies a watch is never going to leak in any circumstance; the fact is that if enough water pressure is applied to any watch will leak. 

Some Rolex watches are near waterproof because their level of water resistance is so high that they are almost waterproof.

Rolex Ultimate Water Resistance

The world record for the deepest scuba dive is 534 meters. The Rolex Sea Dweller has a 1200m/4000ft depth water resistance, and the Rolex Deepsea has a depth rating of 3900m/12800ft.

The level of water resistance is so high that no human can survive these depths. Therefore, some Rolex are considered waterproof.

Rolex watch company present their Rolex Datejust as 'guarantee waterproof to a depth of 100m/330ft' and for the Rolex Submariner as 'guarantee waterproof to a depth of 300m/1000ft'.

Rolex Watches Waterproof Background

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

Rolex Real Life Water Resistance Performances

Most watch brands claim their watches are water resistant, but only a few have given a real life demonstration outside the test lab. Watchmakers like Rolex are one of the few companies that have succeeded in doing it.

Waterproof performance has been consistently demonstrated by the Swiss watchmaker. Rolex manufactures watches with such a high water resistance that they are able to dive deeper than professional divers can. A prototype Rolex Sea Dweller survives an actual twelve thousand meter dive in the ocean. By pursuing extreme depth ratings, Rolex showcases its ability to manufacture water resistant watches above and beyond its competitors.

Having a Rolex Datejust guaranteed waterproof to a depth of 100 meters/330 feet by a manufacturer that knows the ins and outs of water resistance means the kind of peace of mind you want when you buy an expensive 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 Datejusts 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 Sea Dweller 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.

As a final note

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.
