Water resistance and waterproofness are probably important considerations when purchasing or owning an expensive timepiece like a Rolex Datejust. (The following issue may also be of interest to you: why buy a Rolex Daytona expensive?)
Rolex Datejust watches come with a 100 meters or 300 feet waterproof guarantee. Water resistance is a significant strength of Rolex watches. From creating the first water-resistant watch in 1926 to continuing to improve in this area, Rolex has led the way.
Datejust timekeepers are water resistant up to 10 ATM/100m/300ft. Rolex Datejust wrist watches can go in the water, and they are suitable for swimming, but they are not suitable for diving. The Submariner was created for scuba diving and is waterproof to 300 meters/1000 feet.
With his Rolex Oyster wristwatch, he increased water resistance in timepieces. The Rolex Oyster watch, which he invented, was a major advancement in wristwatch water resistance. Here is the page where you can find information about Rolex Submariner gold and steel price specifically. Every Rolex Datejust comes with an Oyster case that protects the model from water up to 100m(300ft).
The model is made up of water-resistant components. Many other wristwatch companies employ screwed-on case backs. The Rolex Datejust has a threaded Oyster casing with a centre case that screws down the wristwatch's components. Update: A question that is related indirectly but also directly is the following: are real Rolex Datejustes waterproof?
The Rolex Datejust Oyster case compresses the gaskets to hermetically seal the watch. Because of the compression of the gaskets, water is repelled from the case more effectively.
Rolex Datejust can go in the water because of the way they are designed. As the founder of Rolex, Hans Wilsdorf, he was focused on protecting the timekeeper from water and dust. To preserve accuracy and endurance, the wristwatch mechanism must be protected from the elements by an airtight housing.

Hans Wilsford developed and patented the Oyster, a water-resistant model case, in 1926. The Rolex Oyster model case is the core of every modern Rolex Datejust. Like a submarine hatch, every element of the case is threaded and screwed down. Internal gaskets keep the wrist watch movement inside the case hermetically sealed. This system outperforms screw-in model cases.
Wristwatches that are water-resistant have historically had a weak point in their winding crown. It makes no difference how waterproof the crown stem is if it creates a hole in the case. Watchmakers have struggled with the opening on the side of the watch casing. Water does not penetrate the stem because of the gasket around the crown.
The water resistance of a wrist watch is compromised by 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 revolutionary Twinlock technology of the Rolex Datejust outperforms the traditional crown gasket in terms of water resistance. A threaded stem crown is installed in addition to the threaded crown that is screwed into the casing. Water-resistance is improved by Rolex’s Twinlock system, which combines threaded stems with rubber o rings. A number of gaskets are compressed within and around the crown stem.
To start a Rolex watch, you must first remove the crown and rotate it. Waterproofing is less effective in watches with crowns than in wristwatches without them. A crown stem allows water to enter through a tube. The model loses its watertightness when the crown is removed. Rolex wristwatches can be damaged by moisture and dust. In fact, Rolex has been improving the water resistance of its crown for decades.
The innovative Twinlock screw down crown of modern Rolex Datejust watches is guaranteed resistant up to 100 meters. A double waterproofness system is fitted to the Twinlock winding crown on the Datejust. There are two sealed zones, one inside the tube and one inside the crown. When the crown is screwed down, the Datejust is guaranteed waterproof to 100 meters depth. Unlike other watches, the Twinlock provides superior water resistance when the crown is screwed down. When used properly, the Rolex Datejust has a water resistance capacity of 100 meters or 300 feet. It should be remembered, however, that the Rolex Datejust waterproof guarantee will require servicing and maintenance during its life.
