The Heuer Monaco watch was introduced in 1969 in honor of the Monaco Grand Prix. And in honor of this year's GP I made this blog post. This awesome watch was popularized in 1971 when Indianapolis native Steve McQueen wore it in Le Mans, the movie. The Calibre 12 Automatic Chronograph was revolutionary for being the first automatic chronograph in a square case. and tag has updated the Monaco Calibre 12 Automatic Chronograph and released a new version recently.
