From the start, Rolex concentrated on precision. Rolex was the first wristwatch in the world to receive a Chronometric Preciison certificate in 1910. This is just one of the many challenges involved perfecting the chronometric precision movements of the the Rolex watches. Rolex continued to strive to perfecting its precision and awarded the class “A” precision certificate in 1914 by Kew Observatory of Great Britain. Receiving this award, Rolex proved itself renowned for its precision watch movements over again. Rolex belongs to a very small and exclusive club of Swiss watchmakers, where 100% of the watch movements are chronometer certified by the COSC. COSC stands for the French term “Contrôle Officiel Suisse des Chronomètres”. In English it means: “the Official Swiss Chronometer Testing Institute”. The tests involve accuracy and reliability.

Waterproofness

In 1926, Rolex designed the first water resistant watches – using the oyster shaped case, called the “oyster case”. And the brand has long been associated with diving, professional divers and the challenges to go deeper and further. Rolex continued its quest for diving deeper and to develop high quality divers watches for that purpose. Rolex has successfully invented the most well made divers watches. The famous Rolex divers watches- the Submariner and the replica Rolex Sea Dweller have travelled to the bottom of the ocean. 

What’s more, Rolex was always striving to prove itself as a reliable brand name. In 1927, a female swimmer Mercedes Gleitze crossed the English Channel with the the very first waterproof wristwatch-the Rolex Oyster. Both the swimmer and the Rolex completed the trip to perfection, and Rolex published an article in the Daily Mail celebrating the trip and this made the Rolex Oyster famous for its dependability. In 1953, the first people to climb Mount Everest – Tenzig Norgay and Sir Edmund Hillary, were wearing Rolex Oyster Perpetual watches. In 1960, the experimental bathyscaphe Trieste descended into the Mariana Trench, the deepest known depression on the Earth’s surface, with a Rolex Deep Sea Special experimental watch attached to the outside of the vessel. After reaching a depth of 10,916 metres, the watch emerged in perfect working order.
