In the case of expensive wristwatches like Rolex Milgauss, you probably want to know about their water resistance and waterproofness. Here is another topic you should also read about if you are interested in this topic: how frequently service Rolex?
With Rolex's Milgauss timepiece, waterproofness is guaranteed up to 100 meters. Water resistance is one of Rolex's strongest points. From creating the first water-resistant wristwatch in 1926 to continuing to improve in this area, Rolex has led the way.
Rolex manufactures Milgauss wristwatches water resistant up to 100 meters or 300 feet. Rolex Milgauss wristwatches are water resistant and may be worn while swimming, but they are not ideal for diving. Rolex's Submariner wristwatch offers a water resistance of 300m/1000ft - perfect for scuba diving.
Hans Wilsdorf, the founder of Rolex, designed water-resistant timepieces. He upgraded watch water resistance with his Rolex Oyster watch. There are often certain terms associated with this topic, such as Air King Rolex watches. The Oyster case on every Rolex Milgauss model makes it water resistant to a depth of 300ft or 100 meters.
Waterproof components are used in the construction of Rolex Milgauss timekeepers. Some manufactures utilise screws to secure their casebacks, whereas Rolex uses Oyster cases, which secure the watch element to the central case with a screw. This question relates indirectly to, but is also directly relevant to, the previous one: how to stop second hand on Rolex watch?
By compressing the gaskets, the Rolex Milgauss Oyster case hermetically seals the timekeeper. Due to the compression of the gaskets, sealing the case results in a higher level of water resistance.
The design of Rolex Milgauss models allow them to be worn in water. Protecting the wrist watch against water and dust has been a key focus for Rolex founder Hans Wilsdorf. The watch movement must be protected by a dry and airtight housing to ensure wristwatch accuracy and lifetime. It is common to find terms like Rolex Submariner watch buy online with this question.
Water-resistant wristwatch cases were invented by Hans Wilsford in 1926 and patented under the name Oyster. Every current Rolex Milgauss is built around the Rolex Oyster watch casing. Like a submarine hatch, every aspect of the case is threaded and screwed down. For securing the timekeeper movement inside hermetically, gaskets seals are added to the case. The technique is incredibly efficient and outperforms watch casings that are sealed with screws.
The weakest element of water-resistance timepieces has always been the winding crowns. If the crown stem causes an opening in the case, it doesn't matter how watertight it is. This aperture on the side of the case has proven difficult for manufacturers. Most watchmakers use a gasket around the crown stem to prevent water from penetrating.
A wristwatch's crown stem hole is the soft spot in terms of water resistance. There is a hole in the case edge through which the crown stem connects to the movement. During the continual rotation, winding, and turning of the crown, the crown seal is repeatedly compressed, chafed, and stressed.
For improved water resistance than typical crown gaskets, Rolex Milgauss employ the innovative Twinlock mechanism. An additional threaded stem crown has been added along with the timekeeper's threaded crown that screws into the case. Threaded stems and rubber o rings are used in Rolex's Twinlock mechanism to make it more watertight. This system compresses many gaskets inside and around the crown stem.
Watches with mechanical movements, like the Rolex, have a crown that is pulled out and rotated to operate. The crown is a weak point for watch water resistance. The crown stem and tube create an opening for water to get in. The timekeeper is no longer waterproof when the crown is removed. A Rolex can become wet or dirty and collect particles. For decades, Rolex has been working to improve the water resistance of their crown.
Waterproof to 100m(300ft) is assured on all Rolex Milgauss with unique Twinlock screw down crowns. With the Twinlock winding crown, the Milgauss has a double waterproofness system. This device is designed with two sealed zones, one inside the tube and one inside the crown. As long as the Milgauss 's crown is screwed down, its water-resistance is guaranteed to 100m(300ft) depth. Unlike other watches, the Twinlock provides superior water resistance when the crown is screwed down. With proper care, the Rolex Milgauss is waterproof to 100 meters or 300 feet. It's worth noting, though, that the Rolex Milgauss waterproof guarantee will need to be serviced and maintained over time.
