This model doesn't need much introduction... It's the oversize Breitling Navitimer Chrono-Matic from the early 70's with the famous Cal 11 Buren calibre. Because of the big size; 47mm it's also called the pizza with ref 1806. But, it doesn't wear that big on the wrist as it's quite slim due to the movement (which also powers the Heuer Monaco). This example is in lovely all original condition and just serviced. Attached is a great tropic racing style strap. You get a lot for your buck!
