Manufactured by Matthey Tissot for Breguet, the Type XX existed in both civilian and military versions; the military examples being used for test pilots (CEV - Centre d'essai en vol) and for the French navy. Manufactured from 1954, the civilian version was sold in 1970, to the company Aero-Shopping in Paris in the amount of NF 664. This example was therefore sold during the last year of this Type XX design and as been kept in very good condition with a nice and thick case. An already iconic chronograph for the discerning collector.
