Based on a 1972 military standard produced in limited edition for pilots of the Saab 37, on of the most advanced jet fighters of its time, the SIDUNA Aviation chronograph blends aviation History with watchmaking tradition.

SIDUNA's rendition is produced in a numbered edition and has been upgraded with a sapphire crystal and a custom self-winding calibre built by Alfred Rochat & Fils on top of the ETA 7750.
