When it comes to why Rolex demands such respect, one must keep in mind its history and the expert craftsmanship it has demonstrated over the years. Among the many successful innovations and creations it has provided to the watch industry, the most noteworthy is the Rolex Oyster case.
Its main function is to allow magnification of the date on many Oyster replica watches. This additional feature, exclusive to the crystal, allows the wearer to read the date very easily. Because of its uniqueness, and the success this innovation has enjoyed, Rolex was quick to warn all brands planning to adopt the same feature.” To all watchmakers: we draw your attention to the fact that watch lenses with specially shaped magnifying glasses are exclusive to Rolex and are protected both in Switzerland and abroad. We will not hesitate to take legal action against any counterfeiting,” noted a notice published in the press at the time.
In order to achieve maximum water and dust resistance, the Oyster case is fixed to models that are primarily diving watches. It was therefore imperative to provide replica Rolex customers with a feature that would allow them to use their watches in dark conditions, such as underwater. To meet this need, Rolex began using an innovative luminescent material called Chromalight. This material emits a blue glow that provides greater visibility and also extends the time of visibility in dark conditions. Applied to the hands, hour markers, and other display elements of most Oyster watches, the high-performance luminescent material makes it easy for the wearer to tell the time in dark conditions. Chromalight displays glow for almost twice as long as standard luminescent materials, extending to more than eight hours.
Mostly found in Sea-Dweller and Rolex Deepsea, the helium relief valve allows for the release of excess pressure that builds up in the case during the diver’s decompression phase. This is done in a hyperbaric chamber and does not affect the water-resistance of the watch. This innovative feature was developed and patented by Rolex back in 1967 and it soon played a key role in the field of deep-sea diving. The presence of a helium relief valve allows divers to make deeper dives and stay underwater for longer periods of time. As with saturation diving, the watch accompanying the diver housed a feature that released the helium absorbed by the watch.
When fake Rolex created the Oyster case, it was understood that in addition to the robustness of the case, the bezel was one of the most visible parts of the watch that was susceptible to external corrosion. It also features 100% color retention and excellent polish to ensure that the bezel retains its luster over time. All Rolex Oyster cases are subjected to rigorous water resistance tests. Each case is immersed in water and subjected to pressure 10% greater than its guaranteed depth – 35% greater for diving watches.
