The Navitimer was introduced in 1954 and aside from some very rare early Valjoux 72 models, the watch was equipped with the equally excellent 17-jewel Venus 178. 

Although this is a vintage watch, the Breitling Navitimer 806 comes as in a large 41mm case with 22mm lug width; it’s a big vintage watch with modern size! 

This loverly vintage Navitimer just came back from a full service, comes on a new (generetic) leather strap.
