This “Official Cosmonauts’ Chronograph” is the first automatic model with a mechanical alarm. Set with the crown, it rings for 20 to 25 seconds without running down the power reserve. It can be interrupted or stopped with a pushpiece at 8 o’clock. The movement is now being tested in extreme conditions on the Starship Millennium Voyage, for which Fortis is an official supplier. This exceptional model comes in a platinum case in a limited edition of 100 pieces.
