A first to celebrate the brand’s 85th anniversary : the Fortis Official Cosmonauts’ Chronograph now features an alarm function, to the joy of all cosmonauts ! This new patented mechanical calibre features an alarm device which rings for 20 to 25 seconds, without affecting the power-reserve. The function is activated with the push piece at 8 o’clock, and the alarm time is set by turning the crown to position the centre hand with the red triangle. Limited edition of loo in platinum.
