Zenith Rainbow El Primero Fly-Back Pilot's Watch

In 1997 the French Air Ministry made a request to Zenith to make a chronograph sturdy enough to withstand the toughest of conditions. The brand produced this amazing chronograph, the movement is the legendary EL PRIMERO automatic with a fly-back function (the chronograph can be stopped, zeroed and restarted just by pushing the bottom button- a true complication!) It was also made available to the public. This watch is offered in fantastic condition, a thorough service has been completed, all the bracelet links, box and papers dated 1998.
