Founded in 1905 by Hans Wilsdorf, Rolex watches are famous for their durability. They go through testing in Switzerland to ensure that they meet high quality standards. According to Rolex.com, the testing includes a crash test, a waterproof test, a deep sea test and multiple drop tests. The Rolex watch received the Swiss Certificate of Chronometric Precision in 1910 as well as an award in 1914 for class A precision from the Kew Observatory in Great Britain.
