The Master Time 8-day clock had the longest run of any of the dash-mounted Heuers, tracing its history back to the Hervues of the 1930s.  Heuer first used the “Master Time” name in 1958 and the clock continued in production until 1985, making the transition from metal cases to plastic and from mechanical movements to quartz.

For rally timing, the early Hervue clocks were paired with Autavia stopwatches on a double back-plate.

Later, the Master Time 8-day clock was paired with a Monte Carlo 12-hour stopwatch to create the Rally-Master pair.  The Rally-Maaster pair became almost standard equipment for many rally teams of the 1960s.

History of the Master Time

A summary history of the Master Time is as follows:

  • 1933: Hervue 8-day clock (also marketed under the name “Hervue Junior”) introduced as companion to the Autavia; powered by Revue Thommen GT movement (two-barrel); numerals 1 through 12 on dial; second hand at bottom of dial (6:00 o’clock)

  • next version of the dial has “Hervue” name above Heuer logo; second hand remains at bottom of dial (6:00 o’clock)

  • next version of the dial has Heuer logo above the words “8 days”; second hand remains at bottom of dial (6:00 o’clock)
  • 1958: Heuer introduces the “Master Time” 8-day clock; “Master Time” name above Heuer logo at top of dial; “8 Days” at bottom of dial; dial has numerals 3-6-9-12; powered by Revue Thommen 63 movement; double-barrel; center seconds (thick second hand); hack feature

  • early 1960’s: Arogno 28 movement (single barrel) replaces the Revue Thommen 63 movement (double barrel); center seconds hand is thinner; hack feature
  • 1968: dial now has has numerals 1 through 12, rather than the previous 3-6-9-12.  Case becomes thicker to match the thickness of the new two-button version of the Monte Carlo.

  • 1968: GMT / 24-hour version introduced (hour hand makes one revolution in 24 hours)

  • 1975/76: plastic case introduced; continues to use Arogno 28 mechanical movement.
