Zenith's collections are built around two prestigious movements, one of which is the El Primero chronograph. The manufactory's automatic chronograph Rainbow Fly-Back model was developed in collaboration with civil and military aviation experts. The bezel, counters, hands, crown and push-button were designed for optimal flight use. With the fly-back complication, a new period of time can be measured instantaneously by using just one push-button.
