Historic details

The manual-wind Navitimer Cosmonaute 819 holds a Venus cal. 178 in a new, quite revolutionary case design. Developed together with EPSA Piquerez, the famous casemaker, the "Big Case" introduces a complex bezel mechanism, that allows high waterproof ratings. At a 48mm diameter, it was huge for that period. Most examples are marked with the patent application number "DDE + BR 11525/67" from August 1967. The last production batches carry the patent publication number 486728 from February 1970.

The Navitimer Cosmonaute ref. 819 has "Big Eyes" hour and minute counters and "running seconds" at 9. Red accents feature on both dial and slide rule. Logos are "Twin Jet" for Breitling-distributed Navitimer or silverwhite printed AOPA-signed wings.
