Rolex SA is a Swiss luxury watchmaker. The company and its subsidiary Montres Tudor SA design, manufacture, distribute and service wristwatches sold under the Rolex and Tudor brands. Founded by Hans Wilsdorf and Alfred Davis in London, England in 1905 as Wilsdorf and Davis, Rolex moved its base of operations to Geneva, Switzerland in 1919.
Although they had a great company name, Wilsdorf and Davis still needed a great company logo. In 1925 the two businessmen trademarked their five-pointed coronet insignia, which has grown to become instantly recognizable throughout the world. - See more at: https://www.bobswatches.com/rolex-blog/rolex-info/the-history-of-the-rolex-logo-is-exquisite.html#sthash.5eAwTkRh.dpuf
