Dates to 1950s - believe when I looked up the serial it was 1958 specifically. Landeron 47 movement, which is the first cam actuated movement ever. Pretty cool. 34mm 18k rose gold plated case. Chronogrpahe Suisse in the 1950s operated mainly out of Swiss airports, offering watches people can buy as a souvenir from Switzerland (damn times have changed lol). Love that bit. $765 shipped CONUS
