1960's Breitling Navitimer Cursive B 806 Red Box 10

First, there's the very rare logo: a cursive "B" and "Breitling Genève" in silver ink. This dial was only used for about a year and a half in 1967 and 1968. Then there are the "Red Box 10s" – starting in about 1967, Breitling began to put red boxes around the 10 indicators on the slide rule. They only did this up to 1969. This piece has the original matched set (replacement outer scales typically omit the boxed 10).
