Hi,
After much time spent through my books about Jim, I made an important discovery.
Between 1967 and 1968 Jim Clark wore a Breitling Navitimer 806.
My eye fell on a picture of the Nurburgring 67, and have started the search.
In 1966 Jim wore a Top Time, as stated by Breitling in the book for the 125th anniversary of the Company.
But since 1967, and until April 1968, Jim Clark wore constantly his Navitimer ref.806.
On every track,included Indianapolis 1967.
My sincere apologizes for the article in Italian, and I hope you enjoy my work.
Best.
