When buying or owning a high-end watch like a Rolex, water-resistance and waterproofness are undoubtedly key factors to consider. Rolex is a watch guarantees waterproof up to 100 meters. One of Rolex's greatest advantages is its water resistance. Rolex manufactured the world's first water-resistant watch in 1926. In this field, the company continues to innovate.
Rolex watches are water resistant up to 100 meters. Although Rolex watches can be submerged in water, they cannot be used for diving. The Submariner collection from Rolex is a scuba diver's watch with a water resistance of 300 meters/1000 feet.
Hans Wilsdorf, the founder of Rolex, designed water-resistant timepieces. His invention, the Rolex Oyster watch, signified a significant advance in the water resistance of timepieces. All Rolex models with the Oyster case have a water resistant rating of 10ATM the equivalent of 100 meters (300ft).
There are waterproof components in Rolex watches. While some watch manufacturers use screws to secure their casebacks, Rolex uses Oyster cases, which screw the watch element into the central case. The Rolex Oyster watch is hermetically sealed with compression gaskets inside the case. By squeezing the gaskets once the case is sealed, you can achieve a higher level of water resistance.
Water-resistant cases are featured on Rolex watches. Protecting the watch against water and dust has been a key focus for Rolex founder Hans Wilsdorf. The wristwatch movement must be protected from the elements by an airtight case to maintain accuracy and longevity.
An Oyster watch case designed by Hans Wilsford was patented in 1926 and proved to be water-resistant. The Rolex Oyster case is the foundation of modern Rolex timepieces. Every section is threaded and screwed together, just like a submarine hatch. Gaskets seals are applied to the casing to hermetically seal the watch movement inside. A watch case sealed with this system performs better than those sealed with screws.
The winding crown has always been a weak spot in water-resistant watches. The crown stem will create a hole in the case, even if it is waterproof. Watchmakers have found it difficult to create cases that open on the side. Many watchmakers add a gasket around the crown stem to prevent water from entering.
Water resistance of a watch is fragile around the crown stem hole. The crown stem is connected to the movement through a hole in the case edge. The crown seal is compressed, chafed, and stressed when it is rotated, wrapped, and turned to alter the time.
The unique Twinlock technology on the Rolex provides better water resistance than the traditional crown gasket. A threaded case crown screws on to the watch, as does a threaded stem crown. Twinlock enhances water tightness by combining threaded stems with rubber o rings. Within the crown stem and around it, this system compresses multiple gaskets.
The crown must be lifted out and rotated to operate a mechanical watch, such as a Rolex. Watches with crowns are less waterproof than those without. Water is able to enter through the crown stem and tube. When the crown is unscrewed, the watch becomes non-watertight. Moist and dust can infiltrate a Rolex. The water resistance of Rolex's crown has been improving for decades.
Up to 100m(300ft) is the water resistance guarantee of the modern Rolex crown patented by Twinlock. have a Twinlock winding crown featuring a double waterproofness system. This device is designed with two sealed zones, one inside the tube and one inside the crown. The 's crown is guaranteed waterproof to 100 meters or 300 feet when screwed down. In comparison to other watches on the market, the Twinlock offers an extraordinarily high level of water resistance by screwing down the crown. The Rolex will remain resistant to 10 ATM/100m/300ft if you use it as intended. It should be remembered, however, that the Rolex waterproof guarantee will require servicing and maintenance during its life.
