Fortis Watch Cosmonautis Classic Steel Limited Edition 401.21.72 L.28. Ever since their orbital baptism of fire aboard the space station MIR in 1994, FORTIS watches have been part of the standard equipment of all Cosmonautis. After 100,000 orbits around the earth and the longest stay in weightlessness of any watch, FORTIS embodies reliability in time and space. FORTIS has proved itself again and again like no other brand and is therefore a true pioneer and a specialist in the field of space travel. Alongside the Official Cosmonautis watches with solid steel bases and engraved missions, this year FORTIS is launching a new version which embodies the features of the first original.
