The Master Time has the longest history of any of the dash-mounted Heuers, tracing its history back to the Hervues of the 1930s, bearing the name "Master Time" from the late 1950's and continuing in production through 1985. While the dials changed considerably over the years (as shown below), the mechanical Master Times were powered by three basic movements over the years.
