This is a lovely vintage Breitling 'Old' Navitimer.
 
This watch has a large 41.5mm diameter case, excluding the signed Breitling crown. For its age, the case is in very nice condition with some signs of use. It has a bidirectional bezel. 
 
The black dial which harks back to the original 806 design is in excellent condition. It has been fitted with a replacement plexi crystal. 
 
The automatic movement is running well and keeping great time, with all chronograph functions working correctly. 
 
The watch has been fitted with a brand new genuine Breitling strap and buckle. It comes in a Breitling box with its original and rare instruction booklet.
