Pilot AVIA CLASSIC – Pilot’s Watch with original Molnija 3603 Hand-Wound Movement

Classic B-Uhr / Observation Watch – featuring the rare, decorated Molnija 3603 calibre

The AVIA CLASSIC Molnija 3603 is a traditional pilot’s and observation watch, equipped with a now very rare Russian hand-wound movement. The calibre 3603 is historically based on the Swiss Cortébert calibre 616 and is considered one of the most iconic Russian mechanical movements of its time.

A highlight of this piece is the beautifully finished movement featuring Geneva stripes and blued screws — a level of decoration rarely seen on modern production watches.
