The DD 2020 is Dubois Dépraz's iconic chronograph module designed to mount on ETA 2892-A2 or ETA 2890-2 base movements. It transforms a simple three-hand automatic into a tri-compax chronograph. Extensively used by Omega for their Speedmaster Reduced line (calibers 1140, 1141, 1143, 3220). The module features a vertical clutch system and can be configured in bicompax or tricompax layouts with various subdial arrangements.
