120 years ago, the Curies discovered Radium. However, it was adopted in watches during the first World War. In the early 20th century, Radium was usually used to coated the hands and hour markers. It is the earliest luminescent material. Although the radioactivity of Radium was proved to be harmful to humans in 1920s, it still was the only luminescent material in watchmaking industry.
The first generation of Rolex Submariner fake watch with steel case adopted Radium as its luminescent material too.
Rolex gave up the Radium due to the security problem in 1963. It changed to Tritium. The half-life of cockroaches is only 12 years, so after decades, its luminous life is running low. But what’s interesting is that the hour markers are gradually yellowing after years of baptism. If it is not surrounded by gold, it is highly sought after today.
Rolex kept finding the better representative material always. In 1998, it adopted the Super LumiNova, which is Photoluminescent, offering longer lifetime than Tritium. The last generation of Rolex Submariner was used the Super LumiNova. See the picture please, the popular copy Rolex exudes charming green light at dark night.
The current Submariner has used the Chromalight, which took place of Super-LumiNova in 2008. It was firstly used on Deepsea. Chromalight exudes blue light instead of the green light of Luminova.

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.
Sky-Dweller was first appeared in 2012, becoming the most complex and distinctive Rolex with the complex functions of annual calendar and two time zones display. In our impression, Rolex hasn’t equipped its models with complications but Sky-Dweller is an exception. At that time, it became the one of the most expensive Rolex for the first generation was made from precious metal. The new model released last year provides the Rolesor version, greatly decreasing the prize.
Two time zones
Referring to two time zones watches, Rolex Sky-Dweller copy with blue dial could be considered as the simplest and most beautiful watch which has been designed with the complex function of two time zones display. The red point at 12 o’clock position will indicate the time in your hometown no matter where you are. On the other side, through the central minute and hour hands, you will know the local time.
The function of annual calendar could be considered as the most practical complex function in our time. The annual calendar system of the Oystersteel and white gold case Rolex has been named as Saros. The fixed gear (“the sun”) is located in the center of the movement. The satellite wheel (“Earth”) meshes with the planet wheels within one month and is driven by the date disc. The satellite wheel (“Moon”) is equipped with four teeth, which correspond to four 30-day months: April, June, September and November, which means you never have to bother setting the date or month (The February is an exception).
The revolutionary Ring Command bezel
The more functions a watch owns, the more operations it will take to set it. In general, these adjustments should be made through the crown, but Rolex Sky-Dweller is different. Rolex develops the revolutionary Ring Command system, allowing the functions to be selected by the rotatable Ring Command bezel which interacts directly with the movement.
