This is a huge and original 48mm. 1967 BREITLING NAVITIMER reference 1806 in steel which has NOT been altered in any way-unpolished, original and great looking! Usually the case back writing is worn away-this one is quite clear. The original dial still has the original luminous on the dial (un-touched) and correct baton hands. Usually the black bezel is worn to bare metal-this one look excellent. The automatic winding BREITLING caliber 11 was just meticulously cleaned and operating perfectly. The crown and pushers are correct. This is an honest example for the collector.
