The Buren 1280 movement was the base for the Heuer 11 chronograph movement, created in a secret partnership between Breitling, Heuer-Leonidas, Hamilton/Buren and DuboisDépraz in order to develop the first automatic chronograph. The Caliber11 Chronomatic was presented in March 1969 shortly after the Zenith/Movado presented the first automatic wind chronograph (ELPrimero) in January the same year. The chronograph module DuboisDépraz 8510 has also been used by Valjoux, Cal:7740.
