In 1969, Tag Heuer released the first automatic chronograph. and broke with tradition by ceating the frist square waterproof case to house it.The Tag Heuer Monaco was revolutionary for being the first automatic as well as the first square cased chronograph. The Hollywood film star Steve McQueen used the watch to accessorize his character in the 1971 film Le Mans. In the decades after his death the use of film stills has made the watch synonymous with McQueen. Tag HEUER is my all time fav watch maker! Look at that red on blue it looks SO SEXY!!!!!
