In 1958, Heuer introduced the Monte Carlo 12-hour dash-mounted stopwatch to replace the Autavia. Where the Autavia used traditional round recorders for the hours and minutes, the Monte Carlo features a 12-hour numerical counter in a “window” at the bottom of the dial. Heuer proudly announced that the new central register (for minutes) and jumping disc (for hours) assured the “greatest legibility ever found in a stopwatch”.
Three-button models sold through 1967 used a button to advance or reset the hour disc; two-button models used a single button to reset hours, minutes and seconds. Paired with a Master Time on a double back-plate, the Monte Carlo was one-half of the classic Rally-Master pair.

Functions of the two-button Monte Carlo are as follows:
- start timer by pressing the crown
- press crown again for “time out” / “time in”; may use time out / time in function repeatedly
- stop timer by pressing crown
- press right pusher to reset minute and second hands, and hour disk, to zero
You can read more about the operation of the two-button Monte Carlo in the Instruction Booklet that came with this stopwatch.
