When you're thinking about buying or currently owning an expensive wristwatch like a Rolex GMT Master, you'll probably want to know about water resistance and waterproofness. If you a looking for more info about this, here is a topic you should also read about: how to tell your Rolex GMT-Master II is waterproof?
The Rolex GMT Master is waterproof up to 300ft or 100 meters. Rolex wrist watches are known for their water resistance, which is one of their greatest strengths. With the creation of the first water-resistant wristwatch in 1926, Rolex has continued to improve in this field.
GMT Master models are water resistant to a depth of 10ATM the equivalent of 100 meters (300ft), according to Rolex SA. Although Rolex GMT Master watches may be submerged in water, they are not ideal for diving. The Submariner watch is water resistant to 300 meters/1000 feet, making it ideal for scuba diving.
Hans Wilsdorf, Rolex's founder, was a pioneer in the field of waterproof wristwatches. With his innovation, the Rolex Oyster, he revolutionised watch water resistance. Here is where you may be able to find information about time goes faster in Rolex watch specifically. Every Rolex GMT Master comes with an Oyster case that protects the watch from water for up to 10 ATM/100m/300ft.
Rolex GMT Master watches are built with components that make them waterproof. Other watches use screwed-on case backs, whereas the Rolex GMT Master uses a threaded Oyster case that screws down the element of the wrist watch on the middle case.

The Rolex GMT Master Oyster case compresses the gaskets, hermetically enclosing the timepiece. Due to the compression of the gaskets, sealing the case creates a higher level of water resistance.
Due to the way they are designed, Rolex GMT Master watches can be worn in the water. Hans Wilsdorf, the founder of Rolex, placed a premium on the wrist watch's resistance to water and dust. The timekeeper movement must be protected by a dry and airtight housing to ensure wristwatch accuracy and lifetime.

Water-resistant model cases were invented by Hans Wilsford in 1926 and patented under the name Oyster. The Rolex Oyster watch case is the core of every modern Rolex GMT Master. Like a submarine hatch, every element of the case is threaded and screwed down. Gaskets seals are applied to the casing to hermetically seal the watch movement inside. A wrist watch case sealed with this system performs better than those sealed with screws.
Historically, the winding crown has always been the weak point for water-resistant watches. It makes no difference how waterproof the case is if there is an opening owing to the crown stem. For watchmakers, the case opening on the side has proven difficult. To avoid water infiltration, many watchmakers use a gasket around the crown stem.
In terms of water resistance, the crown stem hole on a wrist watch is the weak place. There is a hole in the case edge through which the crown stem connects to the movement. In order to adjust the time, the crown is repeatedly rotated, wound, and turned, compressing, chafing, and stressing the crown seal.
There is a patented Twinlock system inside Rolex GMT Master models to provide better water-resistance than the classic gasket. A threaded crown screws into the case, and a threaded stem crown has been added. Threaded stems and rubber o rings are used in Rolex's Twinlock mechanism to make it more watertight. Multiple gaskets are packed inside and around the crown stem in this method.
To use a mechanical wrist watch, such as a Rolex, the crown must be removed and rotated. Waterproofing is less effective in models with crowns than in wrist watches without them. The crown stem and tube create an opening for water to get in. The watch loses its watertightness when the crown is removed. Moisture can harm Rolex timepieces. The crown has improved its water resistance since the 1960s.
The innovative Twinlock screw down crown on these current Rolex GMT Master ensures water resistance of up to 10ATM the equivalent of 100 meters (300ft). A double waterproofness system is fitted to the Twinlock winding crown on the GMT Master. In addition to the tube, the crown also features two sealed zones. As long as the GMT Master 's crown is screwed down, its water-resistance is guaranteed to 100 meters depth. When the crown is screw down, the Twinlock provide water resistance above and beyond many other watches on the market. Providing you use the Rolex GMT Master as intended, the wristwatch will remain waterproof to 100 meters. However, keep in mind that the Rolex GMT Master watertfight warranty will necessitate servicing and maintenance over the watch's lifetime.
