Hans Wilsdorf, Founder of premium watch-maker Rolex, was an alleged Nazi spy and sympathised with ex-German Chancellor Adolf Hitler, The Telegraph reported citing previously classified MI5 documents. World War II papers, dated between 1941 and 1943, stated that Wilsdorf was "most objectionable" and "suspected of espionage". Secret agents wanted to blacklist him, a move which would've hurt Rolex.
