TUDOR

In 1905 Wilsdorf launched his own company in England and started producing high quality watches. Then in 1908, he registered the "Rolex" brand in La Chaux-de-Fonds Switzerland. The company remained in England fifteen years approximately and in 1920 moved to Geneva.
It was not until 1946 that Hans Wilsdorf first opened Tudor. Wilsdorf chose the name Tudor because he wanted to honor the Tudor period of England.
The Tudor watches used the Tudor Rose signed on the dial which is the heraldic emblem of England and takes its origin from the Tudor dynasty. Ending 1960's Tudor changes its famous Rose sign for the actual Shield sign.
The main difference between Rolex and Tudor could be seen already in the 40's when the first Rolex Tudor Oyster was introduced: Inside the screwed-in Oyster case, instead of a Rolex manufactured movement, there was a movement supplied by Ebauches SA, ETA.
Throughout the years, Rolex Tudor Chrono models stands out since the brand manufactures them from the beginning with valijoux movements that were modified and improved for Rolex Tudor watches (similar to those manufactured for Rolex chronographs) including exotic dials such as the Rolex Tudor Montecarlo series with diverse colors and designs.
