1970 Heuer Carrera 30 (Ref. 7753 S)

The Carrera was released the same year as the Daytona and chronographs share both the Singer-made dials and the Valjoux cal. 72 movement. They are both named after races famous races too – the Carrera for the extremely dangerous Carrera Panamericana race through Mexico, but the Carrera has many features that set it apart from its contemporaries.

Heuer’s Carrera line was designed with legibility in mind. The goal was to create a chronograph that was sleek and uncluttered. Heuer had patented a new steel tension ring to hold the crystal in place. In order to keep the dial as clean as possible, this ring was painted to feature the 1/5 second demarcations. This along with the basic baton markers helped to create the simple, minimal look Heuer had in mind. The case, manufactured by Piquerez, features sharply beveled lugs that add to the overall streamlined look of the design.

The ref. 7753 S seen here was originally called the Carrera 30 because the minute register measures thirty-minute increments. The ref. 7753 and is the second version of the Carrera 30 produced by Heuer, remaining aesthetically almost the same as its predecessor but featuring the updated Valjoux cal. 7730 movement.
