Recently Phillips auctioned a rare Rolex Sea-Dweller original timepiece Ref.1665, which was sold at a high price: 70,8500 Swiss Francs. The earliest popular fake Rolex Sea-Dweller could date back to 1960s when Rolex cooperated with Comex and United States Army. In order to adapt to saturated deep sea diving, Rolex developed a new patented “helium escape valve” at the side of case on basis of Submariner Ref.5513, later the Ref.5514 was created especially for Comex. While the helium escape valve became the point to distinguish the Sea-Dweller from Submariner.
Referring to the helium escape valve, some people think it is high-technology which can automatically adjust the pressure of interior and exterior of the watch, avoiding the destroy to glass. In fact, the structure of the helium escape valve is very simple. A waterproof rubber ring, a short metal baton and a leaf spring have made up the device. With the development, Rolex copy watch with black dial is water resistant to a depth of 00 meter which is deeper than the Submariner which is to 200 meters. At that time, the Sea-Dweller was still belonging to Submariner.
The owner of the Ref.1665 sold this time was Robert Palmer Bradley, whose job was driving“Deepstar-4000” that was designed by Jacques Cousteau to dive in the area of US east coast and Caribbean, researching the marine geology and biology at that time. In November,1968, Rolex gave him the watch to commemorate the 500 times diving of Deepstar-4000. The engraved words on the caseback of the steel case knockoff watch were lost now.
From the typical Datejust to the classic Cellini, and from sporty Submariner to complex Sky-Dweller, all the Rolex models are of the most recognizable elements. It is exactly the iconic components that constitute a unique Rolex watch. When you know more about each part of Rolex, you will like it better, meanwhile, knowing it better will help you distinguish the real Rolex from cheap replica timepiece.
The world’s first waterproof wristwatch was mounted with the Oyster case, which was patented by Rolex in 1926. The bezel, caseback and crown have been fastened onto the integrated case by the screw, which ensures that the Rolex watches could be water resistant to 100 meters at least. The professional watches such as Submariner and black dial copy Rolex Sea-Dweller are water resistant to 300 meters even 3,900 meters.
The crown plays a key role in guaranteeing the completely waterproofness. As the crown interacts directly with the movement, Rolex recognized that the screw-in crown should be protected well. At present, all the Oyster models have been equipped with Twinlock crown or Triplock crown. Triplock crowns have often been seen on Submariner or Sea-Dweller which were created for professional divers.
Oyster bracelet is the symbolic and basic strap of Rolex which was released in 1930s. Oysterflex strap is also a patented strap of Rolex which looks just like a rubber strap but is with much robustness. The Rolex imitation watch with rose gold case looks more dynamic with the distinctive Oysterflex strap.
The fluted bezel is another symbolic feature of Rolex while some watches have been equipped with smooth bezel.
The Cyclops lens was patented by Rolex in 1950s and it was firstly used in the models of Datejust. Although it was common in nowadays, however, at that time, it was the breaking innovative.

As the pioneer of 904 L stainless steel, Rolex chooses it instead of 315 steel for that 904 L offers greater resistance to the durability and corrosion.
