THE MOVEMENT
The height of precision, the self-winding Oyster movement is entirely engineered and manufactured by Rolex. Robust and reliable, every movement guarantees long-term high performance and is an officially certified Swiss chronometer.
THE PARACHROM HAIRSPRING
A watch is only as precise as its oscillator is regular. Conventional oscillator hairsprings are made of ferromagnetic alloys, leaving them vulnerable to magnetic fields and shocks. After five years of research, Rolex created the blue Parachrom hairspring. Crafted from a paramagnetic alloy, it is unaffected by magnetic fields and up to 10 times more resistant to shocks. Historically, the unique blue colour of the hairspring has been a sign of prestige reserved for only the most accurate timepieces. Today, it guarantees the accuracy of your Rolex.
THE CERAMIC BEZEL
The bezel of a watch can deteriorate when exposed to sunlight or scratches. This motivated Rolex to create a special bezel with a Cerachrom disc. Fashioned from extremely hard ceramic material, it has excellent corrosion-resistant properties, its colour remains unaffected by ultraviolet rays and it is virtually scratch-proof. To inscribe numerals on this hardest of materials, Rolex further developed and patented a unique process. The numerals and graduations are carved before the ceramic hardens; the Cerachrom disc is then covered with either yellow gold or platinum, atom by atom, and polished until only the precious metal in the numerals and graduations remains, permanently. It takes 40 hours to produce a ceramic bezel.
904L STEEL
Rolex uses 904L steel for its steel watch cases. 904L is usually reserved for the chemical industry, where maximum resistance against corrosion is essential. 904L marries perfectly with the other precious metals used by Rolex. A super alloy, 904L is extremely resistant and highly polishable.
A CLASSIC ART
Watchmaking has evolved from being the domain of a single craftsman to the result of the collaboration of skilled specialists. Every Rolex is a symphony of precision: watchmakers, designers, gem-setters and chemists all contribute their know-how and artistry.
