The Heuer Carrera Reference 1153 holds a significant place in horological history as one of the pioneering automatic chronographs and was introduced in 1969, by Heuer to launch the caliber 11, together with the Autavia “Siffert” and the Monaco. Developed through a collaboration between Heuer, Breitling, Hamilton-Buren, and Dubois-Dépraz, this model was part of the groundbreaking "Chronomatic" project, which aimed to create the world's first automatic chronograph movement, caliber 11. Early models were printed with the name “Chronomatic” above the signature. Earl Boen (August 8, 1941 – January 5, 2023) was an American actor and voice actor renowned for his extensive work in film, television, and video games. He is perhaps best remembered for his role as Dr. Peter Silberman, the criminal psychologist in the first three Terminator films: The Terminator (1984), Terminator 2: Judgment Day (1991), and Terminator 3: Rise of the Machines (2003). Notably, Boen was the only actor, besides Arnold Schwarzenegger, to appear in all three of these films, consistently portraying the same character.
