Very rare Breitling EMERGENCY E56121.1 Royal Air Force Squadron ( RAF) for pilot and totally 20 made only( Breitling museum. com) and therefore super rare ! Full set w box , 121.5 freq. tester , manual and certificate ( blank coz only sell to pilot n no need full in ) Just changed battery n tested emergency function . With original bracelet n extra NATO strap.

Also bought extra almost mint cal (coz some digital from the present one faded away due to age though still works properly ) in EBay from England . If service in HK Breitling claims me 15000 HKD as they said can’t find the cal ( actually still available in England ) and need to upgrade to Emergency Ver II and If upgrade will not be original!

Very rare masterpiece and price firmed
