Most terms in the watch industry are universal, regardless of the brand or the watch. However, Rolex likes to play by its own rules, as they come up with another name for their own components and materials. In this article we will explain the most common Rolex terms that you should know.
Cerachrome is the term patented by Rolex for a high performance ceramic bezel that is extremely strong. Cerachrome contains the two words, “ceramic” and “chrome”. “Chrome” is the ancient Greek word for color. If another colored aluminum inlay on the bezel could fade over the time, the Cerachrom bezel would never fade and virtually unscratchable.
Chronergy is a bit more technical, as the term describes the innovative further development of the Swiss lever escapement. As the intersection between the balance wheel and the gear train, the escapement is one of the most vital components of a watch, as it constantly regulates to control the energy transmission.
This makes it even more important to have an escapement that is not affected by magnetism and temperature fluctuations. Rolex has found a solution with the Chronergy escapement, which was first presented in 2015. Practically resistant to magnetic fields and with 15% higher efficiency, this is the latest generation of Rolex escapements.
On the sportier watch models, be they pilot or diver’s watches, naturally have a lot of luminous material on the index and hands, as this was the only way to ensure good readability in low lighting conditions.
While Seiko owned LumiBrite and much of the watch industry relied on the Super-LumiNova, Rolex decided to go for Chromalight. It is a fluorescent powder mixed with liquid resin that is applied to the dial, hands and markers. Chromalight is not only very bright, but also very durable.
While other manufacturers called it “date magnifier,” Rolex called this technology as cyclops. This term refers to a small lens that enlarges the date window at three o’clock. Legend has it that a drop of water landed on the watch glass of Rolex founder Hans Wilsdorf while he was washing his hands. Then he realized his enormous potential. In 1954, the Cyclops magnifying glass was first presented on the Rolex Datejust.
Everose is the 18 carat rose gold material that consists of gold, platinum and copper. Everose is not only a visual treat, but also has good strength and the color will never fade.
The Glidelock function is one of the most useful inventions for everyday use that Rolex has. Glidelock is a mechanism on the clasp that allows you to easily adjust (lengthen / shorten) the bracelet by adding or subtracting up to 2 mm.
This is one of the highest quality and most durable rubber straps on the market. The Oysterflex strap has a metal core made of a titanium / nickel alloy inside, which provides the stability and elasticity required for a strap. The Oysterflex strap was first used on the Yacht-Master 40 model in 2015.
The oscillator from Rolex named Parachrome, has a characteristic blue balance wheel with a Breguet tip curve, the result of five years research has yielded excellent results. This oscillator withstands magnetic fields and withstands physical shocks much better than conventional springs in other watches.
The term is basically used for the Rolex duotone watch that combines gold and stainless steel. Gold can be either yellow or Everose gold, whereas stainless steel always uses Oyster steel 904L. Rolex has been using the name “Rolesor” since 1933.
This is also the term for a duotone watch from Rolex, but Rolesium is the name for a watch with a combination of platinum and stainless steel. Rolesium was first used in 1999 on the Rolex Yacht-Master Ref. 16622.
