I would like to acquire a Breitling Navitimer Reference 81600 that was in the catalogue from from circa 1986 to 1988, an example of which is shown in the attached photos. I am only interested in an all steel variant. Price offered will be dependent on condition and originality, with a premium for an original box and papers. A further premium will be offered if the watch is mounted on a period correct optional Breitling oyster style bracelet as shown in the last photo. I am a longtime watch collector, with both selling and buying references. Please contact me if you have a piece available for sale. Photo credits: 1-3. @VinneD on PuristSPro/Watchprosite Forum 4.
