This is a very early Rally-Master pair, likely dating from 1958 (when the Master Time and Monte Carlo were first introduced). The unique second hands, with luminous inserts, the fine teeth on the bezels, and the low serial numbers on both cases suggest that this pair is a prototype or very early production model of the Rally-Master Pair.

Distinctive features of the early Rally-Master pairs include the wide second hand, on both the Master Time and the Monte Carlo. There is no doubt that this is a genuine "pair" from the factory; double back-plate is marked "Ed. Heuer & Co."

Dials and hands are in their original condition -- beautiful soft patina, with no re-touching. You can keep this pair original or refresh the hands, as you see fit.

The Master Time is powered by this beautiful Revue Thommen 63 movement, the "double-barrel" movement used on the early Master Times.

This is the earliest version of the Monte Carlo, and features the scripted "Monte Carlo" across the center of the dial and the fish-tail on the minute hand.

Bezels of both the Master Time and the Monte Carlo have finer "teeth" than later models; another feature suggesting status as prototype or early prodcution model.

While Heuer did not track the serial numbers of the cases, the numbers engraved on both this Master Time (18005) and the Monte Carlo (15294) are the lowest serial numbers that I have seen for both timepieces. Together with the unique design of the second hands and bezel-edge, this leads me to conclude that this pair was either a prototype or a very early production model.
