You probably want to know about water resistance and waterproofness when you are about to buy or already own an expensive wristwatch like a Rolex GMT Master II. Here is another topic you should also read about if you are interested in this topic: how often shoul I maintain Rolex?
GMT Master II Rolex watches have a waterproof guarantee of up to 10 ATM/100m/300ft. Water resistance is a significant strength of Rolex timepieces. In 1926, Rolex began creating the world's first water-resistant watch. The company has continued to innovate in this area.
Rolex GMT Master II timekeepers are water resistant to a depth of 10ATM the equivalent of 100 meters (300ft). The Rolex GMT Master II can be worn in the water and can be used for swimming, but cannot be used for diving. The Rolex Submariner is water-resistant to 300 meters/1000 feet, making it ideal for scuba divers.
His invention, the Rolex Oyster watch, signified a significant advancement in model water resistance. With his innovation, the Rolex Oyster wristwatch, he revolutionized wrist watch water resistance.

Rolex GMT Master II models are made with waterproof components. Other wrist watches use screwed-on case backs, whereas the Rolex GMT Master II uses a threaded Oyster case that screws down the element of the timepiece on the middle case. (Another topic to consider is are real Rolexes waterproof?) By compressing the gaskets, the Rolex GMT Master II Oyster case hermetically seals the watch. A higher level of water resistance is achieved by compressing the gaskets once the case is sealed.
Because to their design, Rolex GMT Master II watches can be worn while swimming. A major goal of Rolex founder Hans Wilsdorf was to protect the wrist watch from water and dust. To preserve accuracy and longevity, an airtight housing must be used to shield the wristwatch movement from the environment. Visit this site to learn more about expensive Rolex Batman mens watches.
Hans Wilsford invented and patented water-resistant wrist watch casings in 1926 under the name Oyster. The Rolex Oyster watch case is the core of every modern Rolex GMT Master II. Every section is threaded and screwed together, just like a submarine hatch. Gaskets inside the timepiece casing keep the movements hermetically sealed. The technology is far more efficient and effective than screws.
Timekeepers that are water-resistant have historically had a weak point in their winding crown. It doesn't matter how waterproof the case is if the crown stem creates an opening in it. This opening on the side of the model case has been a challenge for watch manufacturers. To prevent water from reaching the crown stem, most watchmakers utilise a gasket.
A timekeeper's crown stem hole is the soft spot in terms of water resistance. Through a hole in the case edge, the crown stem is attached to the movement. The crown seal is continually crushed, chafed, and pressured during the continuous rotation, winding, and twisting of the crown.
The unique Twinlock technology on the Rolex GMT Master II provides better water resistance than the traditional crown gasket. Along with the timepiece's threaded crown that screws into the case, an additional threaded stem crown has been added. Twinlock is a Rolex feature that combines threaded stems with rubber o rings to improve water resistance. This procedure involves packing several gaskets inside and around the crown stem.
The crown on a Rolex timekeeper must be lifted out and rotated to run the timepiece. It is the weak link in the waterproofing of timekeepers. There is an opening for water to get in at the crown stem and tube. The watch is no longer waterproof after the crown is unscrewed and pulled out. Moisture can cause Rolex watches to malfunction. Rolex has been working to improve the water resistance of their crown for decades.
The innovative Twinlock screw down crown on these current Rolex GMT Master II ensures water resistance of up to 10 ATM/100m/300ft. With the Twinlock winding crown, the GMT Master II has a double waterproofness system. This device has two sealed zones, one in the tube and one in the crown. When the crown is screwed down, the GMT Master II is guaranteed waterproof to 100 meters depth. If the crown is screwed down, the Twinlock provides water resistance above and beyond many other wrist watches. The Rolex GMT Master II is waterproof up to 300ft or 100 meters when used properly. It's important to remember that the Rolex GMT Master II waterproof guarantee will require servicing and maintenance over time.
