Rolex is one of the world’s largest luxury watch brands. Rolex was founded in 1905 in London by Hans Wilsdorf, eventually Rolex moved to Switzerland in 1919. The Tudor watch brand is a subsidiary of Rolex. In 1914 Rolex obtained a chronometer certificate (Class A precision certificate) and thus became the first manufacturer of a chronometer wristwatch.
By obtaining the first chronometer certificate, Rolex demonstrated that, in terms of precision, a small wristwatch could rival that of the best timepieces, including pocketwatches, which were the norm at the time. This proof of performance would contribute significantly to the rise of the wristwatch in popularity. On the strength of this achievement, Rolex would eventually become the world’s largest manufacturer of chronometer-certified wristwatches. The Geneva-based brand perfected the concept of the modern watch in 1926 by inventing the waterproof “Oyster” case to protect the movement inside and then, in 1931, by developing the self-winding “Perpetual” rotor movement. Today, all Rolex Oyster Perpetual watches are officially certified chronometers, carrying on the heritage of the pioneering role the brand played in bringing precision to the wristwatch. That milestone feat of miniaturized precision. Rolex went on to innovate constantly and several times brought new technologies to the market that eventually set standards for the whole industry; among them are (according to Wikipedia) the first waterproof wristwatch Rolex “Oyster”, 1926; the first wristwatch with an automatically changing date on the dial (Rolex Datejust ref.4467, 1945); the first wristwatch case waterproof to 100 m (330 ft) (Rolex Oyster Perpetual Submariner ref.6204, 1953); the first wristwatch to show two time zones at once (Rolex GMT Master ref.6542, 1954); the first wristwatch with an automatically changing day and date on the dial (Rolex Day-Date, 1956). Rolex uses only in-house calibers and many automatic movements but also deployed Quartz movements in the 1970s.
