Monte Carlo is a dashboard stopwatch by Heuer.

In 1958, Heuer launched this dashboard stopwatch as the successor to the stopwatch Autavia. In place of the 12-hours counter of the Autavia entered a jumping 12-hours disc which was visible through a window on the lower part of the dial.

Initially a calibre A. Schild 1666 was used, from 1967 a caliber Valjoux 7714.
