In the 1960’s, Heuer produced a series of “Economy” chronographs — models that did not have names (such as “Autavia”, “Camaro” or “Autavia”), and which were usually in chrome-plated cases.  Heuer produced several of these “Economy” chronographs on a private label basis, for Aristo, Clebar, Hamilton and Zodiac.

Heuer introduced its “Daytona” chronograph in 1977, and in 1980 it produced a version of the Daytona for Aristo, although there is no “Daytona” model name on the dial.  This chronograph was identical to the Heuer Daytona, Reference 110.203 B, except for the name on the dial and except that the numerals on the date disc for the Aristo are red.  Inside the caseback, we see “Heuer-Leonidas” and the Cal 12 movement is marked “Heuer.”
