The 3820 Transatlantique is the civilian-spec Type XX — sharing the same flyback movement and 39mm steel case as the military Aéronavale, but built for the discerning collector. Original retail was $10,600. Comparable examples are actively trading at $6,000–$7,000 on the secondary market. This example is priced to move at $5,555 reflecting the absence of box and papers.
