Fortis Watch Aviatis Cockpit One 704.21.18 L.01. The cockpit of todays aeroplanes may have been predominantly digitalised, but there is one instrument for real pilots that just has to be mechanical, automatic, precise, the watch. With the new cockpit models 704.21.18 Fortis Cockpit One and 704.21.19 Cockpit Two, Fortis has once again managed to bring precisely this wish into the 21st century. The Fortis Cockpit One comes in the brand new Flieger Professional bi colour housing, at the same time allowing you a glimpse at the ETA 2836 2.
