The Paraflex is an exclusive and highly efficient shock absorber developed and patented by Rolex. These ensure high performance and adherence to uncompromising requirements in terms of precision, reliability, shock-resistance, efficient self-winding and ease of maintenance. These self-winding mechanical movements, all rigorously certified as chronometers by the Swiss Official Chronometer Testing Institute (COSC), are entirely designed and manufactured by Rolex based on common characteristics. The Perpetual movements that equip the Rolex models play a key role in the reputation for excellence of Rolex watches. This unique testing of the chronometric precision pushes back the boundaries of performance and makes Rolex the benchmark for excellence in mechanical watches.

This exclusive designation attests that it has successfully undergone a series of specific final controls by Rolex in its own laboratories according to its own criteria, in addition to the official COSC certification of its movement. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee. It also began to replace the 12 o’clock hour marker on some dials, such as on the Datejust, in the form of small 18 ct gold appliques. It appeared for the first time on Rolex dials during the 1930s, then on the winding crown in the early 1950s. The Rolex crown, the logo and symbol par excellence of the brand, was registered in 1931. Pioneer in the development of the wristwatch, Rolex is at the origin of numerous major watchmaking innovations, and has registered over 500 patents in the course of its history. The history of Rolex and Swiss watchmaking are inextricably linked. To guarantee excellent precision, in 2000 Rolex introduced a hairspring in an exclusive alloy of niobium, zirconium and oxygen: the Parachrom hairspring. In a mechanical watch, the oscillator is the guardian of time.Ĭomprising a hairspring and a balance wheel, this regulating organ determines the precision of the watch by the regularity of its oscillations. And to ensure that all Rolex watches can live up to these high expectations, every single one is tested to extremes before it is allowed to leave the Rolex site. Rolex watches have proved themselves from the start in the most extreme conditions imaginable – from the depths of the deepest oceans to the summits of the highest mountains, in the air and on the race track.

Introduced in the late 1930s, the Oyster bracelet is a robust metal bracelet with flat three‑piece links, it remains the mainstay of the Oyster collection. Sometimes colours such as champagne are achieved through electroplating with more than half a dozen different metals. Silver-plating is mostly used as a base layer for the sunray finish, where further colour is added to the prepared dial. The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic colour dials such as shades of silver grey, rhodium or ruthenium.
