Rolex has earned its elite reputation not simply by creating precise, superbly crafted timepieces, but also by investing in high-tech research and development that has produced patented technologies. These technologies, unique to Rolex, keep the company in a league of its own.
Hairsprings are one of the key components of a watch that regulate accuracy. All new or redesigned models of Rolex watches contain exclusive Parachrom hairprings, which are made of a material that makes them significantly more resistant to shock and temperature variations. This material also allows them to be completely unaffected by magnetic fields because the handsprings, rather than being made of iron alloys, are composed of an alloy of niobium, zirconium and oxygen. Rolex has patented this Parachrom hairspring as well as the process for turning the spring blue. The blue color traditionally has been reserved for the most accurate and prestigious watches.
In its pursuit of a unique watch that is able withstand extreme dive pressures, Rolex patented an innovation called the Ringlock system. The system uses three levels of ring seals as well as a thicker, domed crystal in the architecture of the watch case. There is also a helium valve that allows any gasses that have penetrated the watch during deep dives to be released as the diver surfaces. This design makes these watches waterproof up to 3900 meters and strong enough to handle even professional caisson dives. Rolex has a patent for its Glidelock clasp, another feature incorporated into dive watches. This clasp allows for tiny adjustments without the need to remove the watch.
Without question, the most identifiable feature of a Rolex is its caliber 3135 movement. Rolex manufactures its moving parts in-house, which provides them with complete control over the unique movement of their timepieces. This exclusive 3135 movement vibrates at a frequency of 28,800 vph, uses jewel technology and winds automatically in both directions. It is certified by the official Swiss chronometer inspectors, commonly known as the COSC. The accuracy of the Rolex 3135 is outstanding, losing less than 1 second of time per day.
Rolex has maintained its reputation as one of the most precise watch manufacturers in history by ensuring that the technology behind its timepieces is as unique as the company itself. The company has invested in developing the most innovative and cutting edge technologies, while still creating watches that are timeless in their design and flawless in their operation. This commitment to absolute quality is why is has been one of the most elite watch companies in the world for almost a century.
