The name “Tudor” was first registered in Geneva by Isaac Blumenthal on December 13, 1906 under registration number 21383. It was then transferred to Philippe Huther de Colombiere in 1926, and finally sold to Hans Wilsdorf in 1936. No one has precise records, but the first traces of the Rolex-produced Tudors appear in the mid-forties, after the Second World War
