The World of Watches (Rolex) by WatchTime

In 1914, Rolex was granted a Class A chronometer certificate. This book tracks the major Rolex Oyster models from 1926 to 2014.

Discover 100 years of Rolex chronometers and Rolex Oyster Watches. The Class A certificate was only given to large marine chronometers. It was the first watch that was as accurate as a chronometer. This would later make Rolex very popular. Later, it would become the world’s greatest manufacturer of luxury watches. In 1926, the Oyster case was invented. In 1931, the self-winding ‘Perpetual’ rotor was invented. Now, all their Oyster models are chronometer certified. Their first watch passed over 45 days of tests and the average daily rate only increased by +1 second/day. A small watch could rival the best timepieces. Hans Wilsdorf was the founder of Rolex and thought the wristwatch was the future of the watchmaking industry. He strived hard to make the best watch possible. To him, precision was very important indeed. By 1950, 90% of the Swiss chronometers were made by Rolex. That is why there is a term ‘Superlative Chronometer Officially Certified’. It has played a central role in the modern watch. The book features some of its key models.
